The Chesapeake Bay (/ˈtʃɛsəpiːk/ CHESS-ə-peek) is an estuary in the U.S. states of Maryland and Virginia. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile (166,534 km2) drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C.
The Bay is approximately 200 miles (320 km) long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is 2.8 miles (4.5 km) wide at its narrowest (between Kent County's Plum Point near Newtown and the Harford County shore near Romney Creek) and 30 miles (48 km) at its widest (just south of the mouth of the Potomac River). Total shoreline including tributaries is 11,684 miles (18,804 km), circumnavigating a surface area of 4,479 square miles (11,601 km2). Average depth is 21 feet (6.4 m), reaching a maximum of 174 feet (53 m). The Bay is spanned twice, in Maryland by the Chesapeake Bay Bridge from Sandy Point (near Annapolis) to Kent Island and in Virginia by the Chesapeake Bay Bridge-Tunnel connecting Virginia Beach to Cape Charles. Known for both its beauty and bounty, the Bay has become "emptier", with fewer crabs, oysters and watermen in past years. Recent restoration efforts begun in the 1990s have been ongoing and show potential for growth of the native oyster population. The health of the Chesapeake Bay improved in 2015, marking three years of gains over the past four years, according to a new report by the University of Maryland.

The word Chesepiooc is an Algonquian word referring to a village "at a big river". It is the seventh oldest surviving English place-name in the United States, first applied as "Chesepiook" by explorers heading north from the Roanoke Colony into a Chesapeake tributary in 1585 or 1586. The name may also refer to the Chesapeake people or the Chesepian, a Native American tribe who inhabited the area now known as South Hampton Roads in the U.S. state of Virginia. They occupied an area that is now the Norfolk, Portsmouth, Chesapeake, and Virginia Beach areas. In 2005, Algonquian linguist Blair Rudes "helped to dispel one of the area's most widely held beliefs: that 'Chesapeake' means something like 'great shellfish bay.' It does not, Rudes said. The name might actually have meant something like 'great water,' or it might have just referred to a village location at the Bay's mouth." In addition, the name is almost always prefixed by "the" in usage by local residents: "The Chesapeake", "The Chesapeake Bay" and "The Bay".
The Chesapeake Bay is an estuary to the North Atlantic, lying between the Delmarva Peninsula to the east and the North American mainland to the west. It is the ria, or drowned valley, of the Susquehanna River, meaning that it was the alluvial plain where the river flowed when the sea level was lower. It is not a fjord, because the Laurentide Ice Sheet never reached as far south as the northernmost point on the Bay. North of Baltimore, the western shore borders the hilly Piedmont region of Maryland; south of the city the Bay lies within the state's low-lying coastal plain, with sedimentary cliffs to the west, and flat islands, winding creeks and marshes to the east. The large rivers entering the Bay from the west have broad mouths and are extensions of the main ria for miles up the course of each river.
The Bay's geology, its present form, and its very location were created by a bolide impact event at the end of the Eocene (about 35.5 million years ago), forming the Chesapeake Bay impact crater and the Susquehanna River valley much later. The Bay was formed starting about 10,000 years ago when rising sea levels at the end of the last ice age flooded the Susquehanna River valley. Parts of the Bay, especially the Calvert County, Maryland, coastline, are lined by cliffs composed of deposits from receding waters millions of years ago. These cliffs, generally known as Calvert Cliffs, are famous for their fossils, especially fossilized shark teeth, which are commonly found washed up on the beaches next to the cliffs. Scientists' Cliffs is a beach community in Calvert County named for the desire to create a retreat for scientists when the community was founded in 1935.
Much of the Bay is shallow. At the point where the Susquehanna River flows into the Bay, the average depth is 30 feet (9 m), although this soon diminishes to an average of 10 feet (3 m) southeast of the city of Havre de Grace, Maryland, to about 35 feet (11 m) just north of Annapolis. On average, the depth of the Bay is 21 feet (6.4 m), including tributaries; over 24 percent of the Bay is less than 6 ft (2 m) deep.
Because the Bay is an estuary, it has fresh water, salt water and brackish water. Brackish water has three salinity zones: oligohaline, mesohaline, and polyhaline. The freshwater zone runs from the mouth of the Susquehanna River to north Baltimore. The oligohaline zone has very little salt. Salinity varies from 0.5 ppt (parts per thousand) to 10 ppt, and freshwater species can survive there. The north end of the oligohaline zone is north Baltimore and the south end is the Chesapeake Bay Bridge. The mesohaline zone has a medium amount of salt and runs from the Bay Bridge to the mouth of the Rappahannock River. Salinity there ranges from 10.7 ppt to 18 ppt. The polyhaline zone is the saltiest zone, and some of the water can be as salty as sea water. It runs from the mouth of the Rappahannock River to the mouth of the Bay. The salinity ranges from 18.7 ppt to 36 ppt. (36 ppt is as salty as the ocean.)
The climate of the area surrounding the Bay is primarily humid subtropical, with hot, very humid summers and cold to mild winters. Only the area around the mouth of the Susquehanna River is continental in nature, and the mouth of the Susquehanna River and the Susquehanna flats often freeze in winter. It is rare for the surface of the Bay to freeze in winter, something that happened most recently in the winter of 1976–77.
The largest rivers flowing directly into the Bay, from north to south, are:
The Chesapeake Bay is home to numerous fauna that either migrate to the Bay at some point during the year or live there year-round. There are over 300 species of fish and numerous shellfish and crab species. Some of these include the Atlantic menhaden, striped bass, American eel, eastern oyster, and the blue crab.
Birds include ospreys, great blue herons, bald eagles, and peregrine falcons, the last two of which were threatened by DDT; their numbers plummeted but have risen in recent years. The piping plover is a near threatened species that inhabits the wetlands.
Larger fish such as Atlantic sturgeon, varieties of sharks, and stingrays visit the Chesapeake Bay. The waters of the Chesapeake Bay have been regarded one of the most important nursery areas for sharks along east coasts. Megafaunas such as bull sharks, tiger sharks, scalloped hammerhead sharks, and basking sharks and manta rays are also known to visit.
Bottlenose dolphins are known to live seasonally/yearly in the Bay. There have been unconfirmed sightings of humpback whales in recent years. Endangered North Atlantic right whale and fin, and minke and sei whales have also been sighted within and in the vicinity of the Bay.
Although the Bay is farther north than its typical habitat range, a male manatee visited the Bay several times between 1994 and 2011. The manatee, recognizable due to distinct markings on its body, was nicknamed "Chessie" after a legendary sea monster that was allegedly sighted in the Bay during the 20th century. The same manatee has been spotted as far north as Rhode Island, and was the first manatee known to travel so far north. Other manatees are occasionally seen in the Bay and its tributaries, which contain sea grasses that are part of the manatee's diet.
The Chesapeake Bay is also home to a diverse flora, both land and aquatic. Common submerged aquatic vegetation includes eelgrass and widgeon grass. A report in 2011 suggested that information on underwater grasses would be released, because "submerged grasses provide food and habitat for a number of species, adding oxygen to the water and improving water clarity." Other vegetation that makes its home in other parts of the Bay are wild rice, various trees like the red maple, loblolly pine and bald cypress, and spartina grass and phragmites. Invasive plants have taken a significant foothold in the Bay; plants such as Brazilian waterweed, native to South America, have spread to most continents with the help of aquarium owners, who often dump the contents of their aquariums into nearby lakes and streams. It's highly invasive, and has the potential to flourish in the low-salinity tidal waters of the Chesapeake Bay. Dense stands of Brazilian waterweed can restrict water movement, trap sediment and affect water quality. Various local K-12 schools in the Maryland and Virginia region often have programs that cultivate native bay grasses and plant them in the Bay.
In 1524, Italian explorer Giovanni da Verrazzano, (1485–1528), in service of the French crown, (famous for sailing through and thereafter naming the entrance to New York Bay as the "Verrazzano Narrows", including now in the 20th century, a suspension bridge also named for him) sailed past the Chesapeake, but did not enter the Bay. Spanish explorer Lucas Vásquez de Ayllón sent an expedition out from Hispaniola in 1525 that reached the mouths of the Chesapeake and Delaware Bays. It may have been the first European expedition to explore parts of the Chesapeake Bay, which the Spaniards called "Bahía de Santa María" ("Bay of St. Mary") or "Bahía de Madre de Dios."("Bay of the Mother of God") De Ayllón established a short-lived Spanish mission settlement, San Miguel de Gualdape, in 1526 along the Atlantic coast. Many scholars doubt the assertion that it was as far north as the Chesapeake; most place it in present-day Georgia's Sapelo Island. In 1573, Pedro Menéndez de Márquez, the governor of Spanish Florida, conducted further exploration of the Chesapeake. In 1570, Spanish Jesuits established the short-lived Ajacan Mission on one of the Chesapeake tributaries in present-day Virginia.
The arrival of English colonists under Sir Walter Raleigh and Humphrey Gilbert in the late 16th century to found a colony, later settled at Roanoke Island (off the present-day coast of North Carolina) for the Virginia Company, marked the first time that the English approached the gates to the Chesapeake Bay between the capes of Cape Charles and Cape Henry. Three decades later, in 1607, Europeans again entered the Bay. Captain John Smith of England explored and mapped the Bay between 1607 and 1609, resulting in the publication in 1612 back in the British Isles of "A Map of Virginia". Smith wrote in his journal: "Heaven and earth have never agreed better to frame a place for man's habitation." The new laying out of the "Captain John Smith Chesapeake National Historic Trail", the United States' first designated "all-water" National Historic Trail, was created in July 2006, by the National Park Service of the U.S. Department of the Interior following the route of Smith's historic 17th-century voyage. Because of economic hardships and civil strife in the "Mother Land", there was a mass migration of southern English Cavaliers and their servants to the Chesapeake Bay region between 1640 and 1675, to both of the new colonies of the Province of Virginia and the Province of Maryland.
The Chesapeake Bay was the site of the Battle of the Chesapeake (also known as the "Battle of the Capes", Cape Charles and Cape Henry) in 1781, during which the French fleet defeated the Royal Navy in the decisive naval battle of the American Revolutionary War. The British defeat enabled General George Washington and his French allied armies under Comte de Rochambeau to march down from New York and bottle up the rampaging southern British Army of Lord Cornwallis from the North and South Carolinas at the siege of Battle of Yorktown in Yorktown, Virginia. Their marching route from Newport, Rhode Island through Connecticut, New York State, Pennsylvania, New Jersey and Delaware to the "Head of Elk" by the Susquehanna River along the shores and also partially sailing down the Bay to Virginia. It is also the subject of a designated National Historic Trail under the National Park Service as the Washington-Rochambeau Revolutionary Route.
The Bay would again see conflict during War of 1812. During the year of 1813, from their base on Tangier Island, British naval forces under the command of Admiral George Cockburn raided and plundered several towns on the shores of the Chesapeake, treating the Bay as if it were a "British Lake". The Chesapeake Bay Flotilla, a fleet of shallow-draft armed barges under the command of U.S. Navy Commodore Joshua Barney, was assembled to stall British shore raids and attacks. After months of harassment by Barney, the British landed on the west side of the Patuxent at Benedict, Maryland, the Chesapeake Flotilla was scuttled, and the British trekked overland to burn the U.S. Capitol in August 1814. A few days later in a "pincer attack", they also sailed up the Potomac River to attack Fort Washington below the National Capital and demanded a ransom from the nearby port town of Alexandria, Virginia.
There were so-called "Oyster Wars" in the late 19th and early 20th centuries. Until the mid-20th century, oyster harvesting rivaled the crab industry among Chesapeake watermen, a dwindling breed whose skipjacks and other workboats were supplanted by recreational craft in the latter part of the century.
The Chesapeake Bay forms a link in the Intracoastal Waterway, of the bays, sounds and inlets between the off-shore barrier islands and the coastal mainland along the Atlantic coast connecting the Chesapeake and Delaware Canal (linking the Bay to the north and the Delaware River) with the Albemarle and Chesapeake Canal (linking the Bay, to the south, via the Elizabeth River, by the cities of Norfolk and Portsmouth to the Albemarle Sound and Pamlico Sound in North Carolina and further to the Sea Islands of Georgia). A busy shipping channel (dredged by the U.S. Army Corps of Engineers since the 1850s) runs the length of the Bay, is an important transit route for large vessels entering or leaving the Port of Baltimore, and further north through the Chesapeake and Delaware Canal to the ports of Wilmington and Philadelphia on the Delaware River.
During the later half of the 19th century and first half of the 20th century, the Bay was plied by passenger steamships and packet boat lines connecting the various cities on it, notably the Baltimore Steam Packet Company ("Old Bay Line").
In the later 20th century, a series of road crossings were built. One, the Chesapeake Bay Bridge (also known as the Governor William Preston Lane, Jr. Memorial Bridge) between the state capital of Annapolis, Maryland and Matapeake on the Eastern Shore, crossing Kent Island, was constructed 1949-1952. A second, parallel, span was added in 1973. The Chesapeake Bay Bridge-Tunnel, connecting Virginia's Eastern Shore with its mainland (at the metropolitan areas of Virginia Beach, Norfolk, Portsmouth, and Chesapeake), is approximately 20 miles (32 km) long; it has trestle bridges as well as two stretches of two-mile-long (3.2 km) tunnels that allow unimpeded shipping; the bridge is supported by four 5.25-acre (21,200 m2) man-made islands. The Chesapeake Bay Bridge-Tunnel was opened for two lanes in 1964 and four lanes in 1999.
Tides in the Chesapeake Bay exhibit an interesting and unique behavior due to the nature of the topography (both horizontal and vertical shape), wind driven circulation, and how the Bay interacts with oceanic tides. Research into the peculiar behavior of tides both at the northern and southern extents of the Bay began in the late 1970s. One study noted sea level fluctuations at periods of 5 days, driven by sea level changes at the Bay's mouth on the Atlantic coast and local lateral winds, and 2.5 days, caused by resonant oscillations driven by local longitudinal winds, while another study later found that the geometry of the Bay permits for a resonant period of 1.46 days.
A good example of how the different Chesapeake Bay sites experience different tides can be seen in the tidal predictions published by the National Oceanographic and Atmospheric Administration (NOAA) (see figure at right).
At the Chesapeake Bay Bridge Tunnel (CBBT) site, which lies at the southernmost point of the Bay where it meets the Atlantic Ocean near Norfolk, Virginia, and the capes of Charles and Henry, there is a distinct semi-diurnal tide throughout the lunar month, with small amplitude modulations during spring (new/full moon) vs. neap (one/three quarter moon) tidal periods. The main forcing of the CBBT tides are typical, semi-diurnal ocean tides that the East Coast of the United States experiences.
Baltimore, in the northern portion of the Bay, experiences a noticeable modulation to form its mixed tidal nature during spring vs. neap tides. Spring tides, when the sun-earth-moon system forms a line, cause the largest tidal amplitudes during lunar monthly tidal variations. In contrast, neap tides, when the sun-earth-moon system forms a right angle, are muted, and in a semi-diurnal tidal system (such as that seen at the CBBT site) this can be seen as a lowest intertidal range.
Two interesting points that arise from comparing these two sites at opposite ends of the Bay are their tidal characteristics - semi-diurnal tide for CBBT and mixed tide for Baltimore (due to resonance in the Bay) - and the differences in amplitude (due to dissipation in the Bay).
The Bay is mostly known for its seafood production, especially blue crabs, clams and oysters. In the middle of the 20th century, the Bay supported 9,000 full-time watermen, according to one account. Today, the body of water is less productive than it used to be because of runoff from urban areas (mostly on the Western Shore) and farms (especially on the Eastern Shore and in the Susquehanna River watershed), over-harvesting, and invasion of foreign species.
The plentiful oyster harvests led to the development of the skipjack, the state boat of Maryland, which is the only remaining working boat type in the United States still under sail power. Other characteristic bay-area workboats include sail-powered boats such as the log canoe, the pungy, the bugeye, and the motorized Chesapeake Bay deadrise, the state boat of Virginia.
In contrast to harvesting wild oysters, oyster farming is a growing industry for the Bay to help maintain the estuary's productivity as well as a natural effort for filtering impurities such as excess nutrients from the water in an effort to reduce the effects of man-made pollution. The Chesapeake Bay Program is using oysters to reduce the amount of nitrogen compounds entering the Chesapeake Bay.
Oysters are hermaphroditic and will change gender at least once during their lifetime, often starting as male and ending as female; there are numerous ways to cook and eat them, as well as recipes and sauces to accompany oyster dishes. One account:
The Chesapeake oyster – sometimes called Chesapeake white gold – has a flavor and texture that begs connoisseurs to come back and shuck just a few more.
The Bay is famous for its rockfish, a regional name for striped bass. Once on the verge of extinction, rockfish have made a significant comeback because of legislative action that put a moratorium on rockfishing, which allowed the species to re-populate. Rockfish can now be fished in strictly controlled and limited quantities.
The Chesapeake Bay is a main feature for tourists who visit Maryland and Virginia each year. Fishing, crabbing, swimming, boating, kayaking, and sailing are extremely popular activities enjoyed on the waters of the Chesapeake Bay. As a result, tourism has a notable impact on Maryland's economy. One report suggested that Annapolis was an appealing spot for families, water sports and boating. Commentator Terry Smith spoke about the Bay's beauty:
The water is glassy, smooth and gorgeous, his wake white against the deep blue. That's the problem with the Chesapeake. It's so damned beautiful.
One account suggested how the Chesapeake attracts people:
You see them everywhere on Maryland's Eastern Shore, the weekend sailors. They are unmistakable with their deep tans, their baggy shorts, their frayed polo shirts, their Top-Siders worn without socks. Some may not even own their own boats, much less win regattas, but they are inexorably drawn to the Chesapeake Bay ... I planned to spend my days boating, eating as many Chesapeake Bay blue crabs as possible and making a little study of Eastern Shore locals. For city folk like me, they're interesting, even exotic –the weather-beaten crabbers and oystermen called "watermen," gentlemen-farmers and sharecroppers, boat builders, antiques dealers – all of whom sound like Southerners with mouthfuls of marbles when they talk. — Susan Spano, Los Angeles Times, 2008
In the 1970s, the Chesapeake Bay was found to contain one of the planet's first identified marine dead zones, where waters were so depleted of oxygen that they were unable to support life, resulting in massive fish kills. Today the Bay's dead zones are estimated to kill 75,000 tons of bottom-dwelling clams and worms each year, weakening the base of the estuary's food chain and robbing the blue crab in particular of a primary food source. Crabs are sometimes observed to amass on shore to escape pockets of oxygen-poor water, a behavior known as a "crab jubilee". Hypoxia results in part from large algal blooms, which are nourished by the runoff of residential, farm and industrial waste throughout the watershed. One report in 2010 criticized Amish farmers for having cows that "generate heaps of manure that easily washes into streams and flows onward into the Chesapeake Bay".
The runoff and pollution have many components that help contribute to the algal bloom, which is mainly fed by phosphorus and nitrogen. This algae prevents sunlight from reaching the bottom of the Bay while alive and deoxygenates the Bay's water when it dies and rots. The erosion and runoff of sediment into the Bay, exacerbated by devegetation, construction and the prevalence of pavement in urban and suburban areas, also blocks vital sunlight. The resulting loss of aquatic vegetation has depleted the habitat for much of the Bay's animal life. Beds of eelgrass, the dominant variety in the southern Chesapeake Bay, have shrunk by more than half there since the early 1970s. Overharvesting, pollution, sedimentation and disease have turned much of the Bay's bottom into a muddy wasteland.
One particularly harmful source of toxicity is Pfiesteria piscicida, which can affect both fish and humans. Pfiesteria caused a small regional panic in the late 1990s when a series of large blooms started killing large numbers of fish while giving swimmers mysterious rashes; nutrient runoff from chicken farms was blamed for the growth.
The Bay improved slightly in terms of the overall health of its ecosystem, earning a rating of 31 out of 100 in 2010, up from 28 in 2008. An estimate in 2006 from a "blue ribbon panel" said cleanup costs would be $15 billion. Compounding the problem is that 100,000 new residents move to the area each year. A report in 2008 in the Washington Post suggested that government administrators had overstated progress on cleanup efforts as a way to "preserve the flow of federal and state money to the project." In January 2011, there were reports that millions of fish had died, but officials suggested it was probably the result of extremely cold weather.
While the Bay's salinity is ideal for oysters and the oyster fishery was at one time the Bay's most commercially viable, the population has in the last fifty years been devastated. Maryland once had roughly 200,000 acres (810 km2) of oyster reefs. Today it has about 36,000. It has been estimated that in pre-colonial times, oysters could filter the entirety of the Bay in about 3.3 days; by 1988 this time had increased to 325 days. The harvest's gross value decreased 88% from 1982 to 2007. One report suggested the Bay had fewer oysters in 2008 than 25 years earlier.
The primary problem is overharvesting. Lax government regulations allow anyone with a license to remove oysters from state-owned beds, and although limits are set, they are not strongly enforced. The overharvesting of oysters has made it difficult for them to reproduce, which requires close proximity to one another. A second cause for the oyster depletion is that the drastic increase in human population caused a sharp increase in pollution flowing into the Bay. The Bay's oyster industry has also suffered from two diseases: MSX and Dermo.
The depletion of oysters has had a particularly harmful effect on the quality of the Bay. Oysters serve as natural water filters, and their decline has further reduced the water quality of the Bay. Water that was once clear for meters is now so turbid that a wader may lose sight of his feet while his knees are still dry.
Efforts of federal, state and local governments, working in partnership through the Chesapeake Bay Program, and the Chesapeake Bay Foundation and other nonprofit environmental groups, to restore or at least maintain the current water quality have had mixed results. One particular obstacle to cleaning up the Bay is that much of the polluting substances arise far upstream in tributaries lying within states far removed from the Bay. Despite the state of Maryland spending over $100 million to restore the Bay, conditions have continued to grow worse. Twenty years ago, the Bay supported over six thousand oystermen. There are now fewer than 500.
Efforts to repopulate the Bay via hatcheries have been carried out by a group called the Oyster Recovery Partnership, with some success. They recently placed 6 million oysters on eight acres (32,000 m2) of the Trent Hall sanctuary. Scientists from the Virginia Institute of Marine Science at the College of William & Mary claim that experimental reefs created in 2004 now house 180 million native oysters, Crassostrea virginica, which is far fewer than the billions that once existed.
There are several magazines and publications that cover topics directly related to the Chesapeake Bay and life and tourism within the Bay region.
The Capital, a newspaper based in Annapolis, reports about news pertaining to the Western Shore of Maryland and the Annapolis area. Chesapeake Bay Magazine and PropTalk focus on powerboating, while SpinSheet focuses on sailing.
Singer and songwriter Tom Wisner recorded several albums, often about the Chesapeake Bay. The Boston Globe wrote that Wisner "always tried to capture the voice of the water and the sky, of the rocks and the trees, of the fish and the birds, of the gods of nature he believed still watched over it all." He was known as the Bard of the Chesapeake Bay.
The Chesapeake Bay Bridge (known locally as the "Bay Bridge") is a major dual-span bridge in the U.S. state of Maryland. Spanning the Chesapeake Bay, it connects the state's rural Eastern Shore region with the urban Western Shore. The original span, opened in 1952 and with a length of 4.3 miles (6.9 km), was the world's longest continuous over-water steel structure. The parallel span was added in 1973. The bridge is officially named the "Gov. William Preston Lane Jr. Memorial Bridge" after William Preston Lane Jr. who, as the 52nd Governor of Maryland, initiated its construction in the late 1940s finally after decades of political indecision and public controversy.
The bridge is part of U.S. Route 50 (US 50) and US 301, and serves as a vital link in both routes. As part of cross-country US 50, it connects the Baltimore-Washington Metropolitan Area with Ocean City, Maryland, Rehoboth Beach, Delaware, and other coastal tourist resort destinations. As part of US 301, it serves as part of an alternative route for Interstate 95 travelers, between northern Delaware and the Washington, D.C., area. Because of this linkage, the bridge is busy and has become known as a point of traffic congestion, particularly during peak hours and summer months.Chesapeake Bay Bridge–Tunnel
The Chesapeake Bay Bridge–Tunnel (CBBT) is a 23-mile (37 km) bridge–tunnel crossing at the mouth of the Chesapeake Bay, the Hampton Roads harbor, and nearby mouths of the James and Elizabeth Rivers in the American state of Virginia. It connects Northampton County on the Delmarva Peninsula and Eastern Shore with Virginia Beach, Norfolk, Chesapeake, and Portsmouth on the Western Shore and South side / Tidewater which are part of the Hampton Roads metropolitan area of eight close cities around the harbor's shores and peninsula. The Bridge-Tunnel originally combined 12 miles (19 km) of trestle, two 1-mile-long (1.6 km) tunnels, four artificial islands, four high-level bridges, approximately 2 miles (3.2 km) of causeway, and 5.5 miles (8.9 km) of northeast and southwest approach roads—crossing the Chesapeake Bay and preserving traffic on the Thimble Shoals and Chesapeake dredged shipping channels leading to the Atlantic. It replaced vehicle ferry services that operated from South Hampton Roads and from the Virginia Peninsula since the 1930s. Financed by toll revenue bonds, the Bridge–Tunnel was opened on April 15, 1964, and remains one of only ten bridge–tunnel systems in the world, three of which are located in the water dominated Hampton Roads area of Tidewater Virginia.
As of May 2018 the Chesapeake Bay Bridge–Tunnel has been crossed by more than 130 million vehicles. The CBBT complex carries U.S. Route 13, the main north–south highway on Virginia's Eastern Shore on the Delmarva peninsula, and, as part of the East Coast's longstanding Ocean Highway, provides the only straight direct link along the East Coast and Atlantic Ocean, between the Eastern Shore and South Hampton Roads regions, as well as an alternate route to link the Northeast U.S.A. and points in between with Norfolk and further south to the Carolinas and Florida. The Bridge–Tunnel saves motorists 95 miles (153 km) and 1 1⁄2 hours on a trip between Virginia Beach/Norfolk and points north and east of the Chesapeake and Delaware Valley, River and Bay without going through the traffic congestion in the Baltimore–Washington Metropolitan Area further west in Maryland and Northern Virginia. The $15 toll is partially offset by some savings of highway tolls in Maryland and Delaware and avoiding often heavy traffic on north-south Interstate 95 (I-95) built in the 1960s and completed in the late 1970s and parallel older United States Route 1 (US-1) from the 1920s. From 1995 to 1999, at an additional cost of almost $200 million, the capacity of the above-water portion of bridges on the facility was increased and widened to four lanes. An upgrade of the two-lane tunnels is currently underway.
The crossing was officially named the Lucius J. Kellam Jr. Bridge–Tunnel in August 1987, 23 years after opening, honoring one of the civic leaders who had long worked for its development, construction and operation; it continues however to be best known as the Chesapeake Bay Bridge–Tunnel. The complex was built by and is operated by the Chesapeake Bay Bridge and Tunnel District, a political subdivision of the Commonwealth of Virginia governed by the Chesapeake Bay Bridge and Tunnel Commission and in cooperation with the state Department of Transportation. Costs are recovered through toll collections. In 2002, a Joint Legislative Audit and Review Commission (JLARC) study commissioned by the Virginia General Assembly concluded that "given the inability of the state to fund future capital requirements of the CBBT, the District and Commission should be retained to operate and maintain the Bridge–Tunnel as a toll facility in perpetuity."
Occasionally because of similar names, the Bridge-Tunnel is often confused with the Chesapeake Bay Bridge (also known as the Governor William Preston Lane, Jr. Memorial Bridge) further north in Maryland crossing the middle portion of the Bay from Annapolis to Kent Island on the Maryland Eastern Shore of Delmarva. It was built with two lanes and a higher suspension segment in the middle from 1949 - 1952, with a second parallel wider span of three lanes in 1973. It is one of the longest and highest bridges in the world.Chesapeake Bay Flotilla
The Chesapeake Bay Flotilla was a motley collection of barges and gunboats that the United States assembled under the command of Joshua Barney, an 1812 privateer captain, to stall British attacks in the Chesapeake Bay which came to be known as the "Chesapeake Campaign" during the War of 1812. The Flotilla engaged the Royal Navy in several inconclusive battles before Barney was forced to scuttle the vessels themselves on August 22, 1814. The men of the Flotilla then served onshore in the defense of Washington, DC and Baltimore. It was disbanded on February 15, 1815, after the end of the war.Chesapeake Bay Gateways Network
The Chesapeake Bay Gateways Network is a partnership program of the National Park Service and a system of over 150 parks, refuges, museums, historic communities and water trails in the Chesapeake Bay watershed. As a partnership program, it is not considered a Unit of the National Park System. Sites in the greater Chesapeake Bay Watershed are eligible to participate in the Network, including sites in the Potomac River basin out to West Virginia and sites in the Susquehanna River basin out to New York State. The Network is managed by the National Park Service's Chesapeake Bay Office in Annapolis, Maryland, which also manages the Captain John Smith Chesapeake National Historic Trail and the Star-Spangled Banner National Historic TrailChesapeake Bay National Estuarine Research Reserve (Maryland)
The Chesapeake Bay National Estuarine Research Reserve is an estuary reserve in Maryland.
The Chesapeake Bay is the largest estuary in the United States and is one of the most productive bodies of water in the world. The Chesapeake Bay National Estuarine Research Reserve reflects the diversity of estuarine habitats found within the Bay and consists of three components:
A 2,087 acres (8.45 km2) freshwater tidal marsh at Jug Bay Wetlands Sanctuary located 20 miles (32 km) from Washington, D.C.
A 726 acres (2.94 km2) freshwater tidal marsh at the Otter Point Creek component 19 miles (30 km) northeast of Baltimore
A 3,426 acres (13.86 km2) salt marsh at the Monie Bay component located 20 miles (32 km)from Salisbury, Maryland.Monie Bay was designation as a reserve in 1985. Jug Bay and Otter Point Creek were designated in 1990
The purpose of the 6,249 acres (25.29 km2) Maryland Reserve, managed by the Maryland Department of Natural Resources, is to manage protected estuarine areas as natural field laboratories and to develop and implement a coordinated program of research, monitoring, education and volunteer activities.Chesapeake Bay National Estuarine Research Reserve (Virginia)
The Chesapeake Bay National Estuarine Research Reserve contains a diverse collection of habitats including oyster reefs, seagrass beds, tidal wetlands, sandy shoals and mudflats. In order to address the diversity of habitats, the Chesapeake Bay-Virginia Reserve established a multi-site system from tidal freshwater to high salinity conditions along the York River estuary. Reserve components include Sweet Hall Marsh, Taskinas Creek, Catlett Island and Goodwin Islands.Chesapeake Bay Retriever
The Chesapeake Bay Retriever is a large-sized breed of dog belonging to the Retriever, Gundog, and Sporting breed groups. Members of the breed may also be referred to as a Chessie, CBR, or Chesapeake. The breed was developed in the United States Chesapeake Bay area during the 19th century. Historically used by area market hunters to retrieve waterfowl, pull fishing nets, and rescue fishermen, it is primarily a family pet and hunting companion. They are often known for their love of water and their ability to hunt. It is a medium to large sized dog similar in appearance to the Labrador Retriever. The Chesapeake has a wavy coat, rather than the Labrador's smooth coat. They are described as having a bright and happy disposition, courage, willingness to work, alertness, intelligence, and love of water as some of their characteristics.Chesapeake Bay deadrise
The Chesapeake Bay deadrise or deadrise workboat is a type of traditional fishing boat used in the Chesapeake Bay. Watermen use these boats year round for everything from crabbing and oystering to catching fish or eels.
Traditionally wooden hulled, the deadrise is characterised by a sharp bow that quickly becomes a flat V shape moving aft along the bottom of the hull. A small cabin structure lies forward and a large open cockpit and work area aft.
The deadrise workboat is the official boat of the Commonwealth of Virginia.Chesapeake Bay impact crater
The Chesapeake Bay impact crater was formed by a bolide that impacted the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch. It is one of the best-preserved "wet-target" impact crater in the world.Continued slumping of sediments over the rubble of the crater has helped shape the Chesapeake Bay.Eastern Shore of Virginia
The Eastern Shore of Virginia consists of two counties (Accomack and Northampton) on the Atlantic coast detached from the mainland of the Commonwealth of Virginia in the United States. The 70-mile-long (110 km) region is part of the Delmarva Peninsula and is separated from the rest of Virginia by the Chesapeake Bay. Its population was 45,553 as of 2010.The terrain is overall very flat, ranging from sea level to just 50 feet (15 m) above sea level. It is characterized by sandy and deep soil. The weather in the area has temperate summers and winters, significantly affected by the Chesapeake Bay and the Atlantic Ocean. The rural area has long been devoted to cotton, soybean, vegetable and truck farming, and large-scale chicken farms. Since the late 20th century, vineyards have been developed in both counties, and the Eastern Shore has received recognition as an American Viticultural Area (AVA).
The region has more than 78,000 acres of preserved parks, refuges, preserves and a national seashore and is a popular outdoor recreation destination for fishing, boating, hiking and kayaking. It is also an important birding hotspot along the Atlantic Flyway at the southernmost tip of the Delmarva Peninsula. There are public beaches at Cape Charles, Kiptopeke State Park, Savage Neck Preserve, Tangier Island and the Chincoteague National Wildlife Refuge abutting the Assateague Island National Seashore.
The area includes 70 miles of barrier islands, the longest chain of undeveloped barrier islands in the global temperate zone and a [[United Nations International Biosphere Reserve]. At the northern end of the Atlantic side is the beach community of Chincoteague, famous for its annual wild pony roundup, gathered from Assateague Island. Wallops Flight Facility, a NASA space launch base, is located near Chincoteague. At the southern end of the Chesapeake Bay coast, the beach community of Cape Charles, a historic railroad town, is home to the Cape Charles Yacht Center, a super yacht service center. The town of Wachapreague on the Atlantic coast is a popular destination for fishing and guided trips out to the wild barrier islands. Onancock, a harbor town on the Chesapeake Bay, has a ferry service to Tangier Island, off the western shore in the Chesapeake Bay, during spring, summer and fall.
The Eastern Shore, geographically removed from the rest of Virginia, has had a unique history of settlement and development influenced by agriculture, fishing, tourism, and the Pennsylvania Railroad. William G. Thomas describes the Eastern Shore during the late 19th and early 20th century as "a highly complex and interdependent landscape". He continues:
It was a liminal place, a zone of interpenetration, where the settlement patterns, speech, demography, and political outcomes defined its place in the South but its engagement with technology and rapid transformation of the landscape betrayed other allegiances, motives, forces, and effects.
The 23-mile-long (37 km) Chesapeake Bay Bridge–Tunnel, which is part of U.S. Route 13, spans the mouth of the Bay and connects the Eastern Shore to South Hampton Roads and the rest of Virginia. Before the Chesapeake Bay Bridge–Tunnel was built in 1964, the Little Creek-Cape Charles Ferry provided the continuation of U.S. 13 across this stretch of water.Elk River (Maryland)
The Elk River is a tidal tributary of the Chesapeake Bay on the Eastern Shore of Maryland and on the northern edge of the Delmarva Peninsula. It is about 15 miles (24 km) long. As the most northeastern extension of the Chesapeake Bay estuary, it has served as one entrance to the Chesapeake & Delaware Canal since the 19th century. The canal and river now serve as one boundary of the Elk Neck Peninsula. The river flows through Cecil County, Maryland, with its watershed extending into New Castle County, Delaware and Chester County, Pennsylvania. Elkton, the county seat of Cecil County, is located at its head. Its total watershed area is 143 square miles (370 km2) (including the Bohemia River), with 21 square miles (54 km2) of open water, so its watershed is 15% open water. It is south and east of the North East River, and north of the Sassafras River.Gunpowder River
The Gunpowder River is a 6.8-mile-long (10.9 km) tidal inlet on the western side of Chesapeake Bay in Maryland, United States. It is formed by the joining of two freshwater rivers, Gunpowder Falls (often referred to locally as "Big Gunpowder Falls") and Little Gunpowder Falls.Middle Peninsula
The Middle Peninsula is the second of three large peninsulas on the western shore of Chesapeake Bay in Virginia, in the United States. It lies between the Northern Neck and the Virginia Peninsula. This peninsula is bounded by the Rappahannock River on the north and the York River on the south, with the Chesapeake Bay to the east. It encompasses six Virginia counties: Essex, Gloucester, King and Queen, King William, Mathews, and Middlesex. Developed for tobacco plantations in the colonial era, in the 21st century the Middle Peninsula is known for its quiet rural life, vegetable truck-farming, and fishing industry.
There are no cities on the Middle Peninsula and little industry. Among the towns found there, West Point has a pulp-and-paper mill. The unincorporated community of Deltaville is a popular spot for city-dwellers seeking a weekend boating on the bay. Tappahannock is a thriving community on the Rappahannock River, and Urbanna has a small but prosperous tourism industry.
Two small land reservations are home to the state-recognized Pamunkey and Mattaponi Indian tribes.
The primary highways on the peninsula are U.S. Route 17 (Tidewater Trail), which connects Fredericksburg with the Hampton Roads area, and U.S. Route 360 (Northumberland Highway), which connects the Northern Neck with Richmond and Danville. Before modern highways existed, passenger ferries and steam freighters linked the entire Chesapeake Bay region.
The two southernmost counties on the Middle Peninsula, Gloucester and Mathews, are now considered to be part of the Hampton Roads metropolitan area. Gloucester County is connected to the Virginia Peninsula by the George P. Coleman Memorial Bridge, which spans the York River. King William County and King and Queen County to the west are part of the Richmond Metropolitan Statistical Area (MSA).Miles River
The Miles River is a 12.9-mile-long (20.8 km) tidal river in Talbot County, Maryland. It is a tributary of the Eastern Bay and is thus part of the Chesapeake Bay watershed.Nanticoke River
The Nanticoke River is a tributary of the Chesapeake Bay on the Delmarva Peninsula. It rises in southern Kent County, Delaware, flows through Sussex County, Delaware, and forms the boundary between Dorchester County, Maryland and Wicomico County, Maryland. The tidal river course proceeds southwest into the Tangier Sound, Chesapeake Bay. The river is 64.3 miles (103.5 km) long. A 26-mile ecotourism water trail running along the River was set aside in July 2011 by Delaware state and federal officials, contiguous with a 37-mile water-trail extending through Maryland to the Chesapeake Bay.Some of the main tributaries that feed the Nanticoke on the west-side include: Cow Creek; Jack Creek; Wapremander Creek; Marshyhope Creek; and the east side: Gravelly Fork and Broad Creek. Notable towns and communities situated along the river include Nanticoke, Bivalve, Vienna, and Sharptown in Maryland; and further north the city of Seaford, Delaware.
According to a study paid for by the town of Vienna, the English explorer John Smith travelled up the Nanticoke River and mapped it, and visited with Native Americans in their settlement, now believed to be Vienna.The river was dredged in 1990 to facilitate shipping travel along the course. As of 2012, a project to once again dredge the channel is on hold for financial reasons.National Capital / Chesapeake Bay Emmy Awards
The National Capitol Chesapeake Bay Emmy Awards are a division of the National Academy of Television Arts and Sciences. The division was founded in 1977 and in addition to granting the National Capitol Chesapeake Bay Emmy Awards, it recognizes awards scholarships, honors industry veterans at the Silver Circle Celebration, conducts National Student Television Awards of Excellence, has a free research and a nationwide job bank. The chapter also participates in judging Emmy entries at the regional and national levels.Oyster buy-boat
Buy-boats, also known as deck boats, were approximately 40–90 foot long wooden boats, with large open decks, found most often on the Chesapeake Bay but also present in the waters off the Washington coastline, which made the rounds to purchase oysters from tongers (fishermen who used long tongs to pull oysters from the water) and dredgers. Once the oysters were transferred to the buy-boat, they were taken to a wholesaler or oyster processing house where they could be prepared for sale. This service allowed fishermen to be more efficient by sparing them the need to return to shore as often. The buy-boats might also buy seed oysters, or spat, to be planted in oyster beds.Buy-boats saw their heyday in the first half of the 20th century when most oysters from the Chesapeake Bay were harvested by tongers in small flat bottomed row boats, or dredged by sail powered skipjacks. Interstate highways, bridges and tunnels such as the Chesapeake Bay Bridge, Chesapeake Bay Bridge Tunnel, the Hampton Roads Bridge-Tunnel, and smaller bridges that span the many tributaries of the Chesapeake Bay were non-existent prior to the 1950s, therefore it was much faster to haul seafood to market by boat than by truck. Many buyboat captains also used their vessels to transport freight such as fresh produce, grain, livestock, and lumber to market during the off-season from May to August when they were not buying oysters.
Some Chesapeake Bay buyboats such as the William B. Tennison began their lives as sailing vessels that were converted for power when internal combustion engines became available, however most buyboats, including those built for power, retained a single sail into the 1930s when engines became more powerful and reliable. Most Chesapeake Bay buyboats had plank-on-frame hulls like the Nellie Crockett, but a few were built as log canoes. The F.D. Crockett is a rare surviving example of this type. They had a rear-mounted deck house over the engine that contained the wheel house that typically had a rounded front with three to five windows, a galley, a head, and bunks for the crew. Some boats also had additional bunks up in the fore-peak for crew members.St. Marys River (Maryland)
The St. Marys River (sometimes spelled St. Mary's River) is a 22.3-mile-long (35.9 km) river in southern Maryland in the United States. It rises in southern St. Mary's County, and flows to the southeast through Great Mills, widening into a tidal estuary near St. Mary's City, approximately 2 miles (3 km) wide at its mouth on the north bank of the Potomac River, near the Chesapeake Bay to the east.Tangier, Virginia
Tangier is a town in Accomack County, Virginia, United States, on Tangier Island in Chesapeake Bay. The population was 727 at the 2010 census. Since 1850, the island's landmass has been reduced by 67%. Under the mid-range sea level rise scenario, much of the remaining landmass is expected to be lost in the next 50 years and the town will likely need to be abandoned.The people who came to settle the island permanently arrived in the 1770s and were farmers. In the late 19th century, the islanders began to become more dependent on harvesting crabs and oysters from the Chesapeake Bay. As the waterman livelihood became more important and more lucrative, there were often conflicts among the oyster dredgers and oyster tongers in the bay, and between those living in Maryland and those living in Virginia.Many who live on Tangier speak a distinctive dialect of American English, which scholars have disputed as derived from a 17th-century English lexicon and phonetics. Linguist David Shores has noted that, while it may sound like a British variety of English, the dialect is a creation of its own time and place off the eastern shore of Virginia. The persistence of this dialectal variety is often attributed to the geographic isolation of the population from the mainland. Tangier Island is listed on the National Register of Historic Places.
