Route description

Pennichuck Brook begins at Silver Lake in Hollis. It flows northeast under NH 122 and into Dunklee Pond, then continues northeast into Pennichuck Pond, on the boundary between Hollis and Nashua. Leaving Pennichuck Pond, it becomes the boundary between Nashua and the town of Merrimack, flowing northeast under Amherst Street (NH 101A), then turning east and flowing into Holts Pond and Bowers Pond. While part of Bowers Pond, it is crossed by the Everett Turnpike. Past the outlet of Bowers Pond, the brook drops into Harris Pond and Supply Pond, then goes under the Daniel Webster Highway (U.S. Route 3) before it flows into the Merrimack River. All of these water bodies are dammed. The brook runs roughly parallel to the Nashua River from Pennichuck Pond to the brook's mouth in Nashua.

Circumferential Highway (Nashua)

The Circumferential Highway is the common name for a bypass route around the city of Nashua in southern New Hampshire, most of which has not yet been built. The purpose of the highway is to provide easier access to the F.E. Everett Turnpike and U.S. Route 3 in Nashua. Most of the highway will be built in Hudson, with small sections also built through the towns of Litchfield and Merrimack as well as the city of Nashua.

The road does not have a state route designation, and is signed as "TO US 3 / Everett Turnpike" in the westbound direction and "TO NH 3A" in the eastbound direction.

Dunstable, New Hampshire

Dunstable, New Hampshire was a town located in Hillsborough County, New Hampshire. It has been divided into several current cities and towns, including Nashua, Hollis, Hudson, Litchfield, and Merrimack.

The town was originally part of a larger town of Dunstable, Massachusetts, when Massachusetts stretched from Rhode Island up to Maine. The original tract of land was bisected by the Merrimack River, an important route for the lucrative fur and log trade. Dunstable was incorporated as a township in 1673. On July 3, 1706, during Queen Anne's War, tribes of the Wabanaki Confederacy raided the town, killing nine while seven of the natives were killed.When the New Hampshire-Massachusetts border was surveyed and adjusted in 1741, the northern part of the town was determined to be in New Hampshire, and was incorporated as a New Hampshire town in 1746. Both the northern New Hampshire half and the southern Massachusetts half prospered, and various villages were formed along the Merrimack, but also along Salmon Brook, the Nashua River, Pennichuck Brook, and the Souhegan River, which also ran through the tract.

Over the years, other towns were formed from parts of the original area on both sides of the state line, and in 1836 the remaining part that still bore the name of "Dunstable, New Hampshire" was renamed "Nashua", after the name of the river that flowed into the Merrimack at the location then referred to as "Indian Head". Six years later Nashua split into "Nashville" and "Nashua", but in 1853 they rejoined and became the "City of Nashua". The name Nashville is preserved in the city's Nashville Historic District, and the name Dunstable can still be found in the streets "New Dunstable Road", "Main Dunstable Road", and "East Dunstable Road" .

Merrimack, New Hampshire

Merrimack is a town in Hillsborough County, New Hampshire, United States. The population was 25,494 at the 2010 census, and an estimated 25,660 in 2017, making it the ninth-largest municipality in New Hampshire.There are four villages in the town: Merrimack Village (formerly known as Souhegan Village), Thorntons Ferry, Reeds Ferry, and South Merrimack.

Merrimack River

The Merrimack River (or Merrimac River, an occasional earlier spelling) is a 117-mile-long (188 km) river in the northeastern United States. It rises at the confluence of the Pemigewasset and Winnipesaukee rivers in Franklin, New Hampshire, flows southward into Massachusetts, and then flows northeast until it empties into the Gulf of Maine at Newburyport. From Pawtucket Falls in Lowell, Massachusetts, onward, the Massachusetts–New Hampshire border is roughly calculated as the line three miles north of the river.

The Merrimack is an important regional focus in both New Hampshire and Massachusetts. The central-southern part of New Hampshire and most of northeast Massachusetts is known as the Merrimack Valley.

Several U.S. naval ships have been named USS Merrimack and USS Merrimac in honor of this river. The river is perhaps best known for the early American literary classic A Week on the Concord and Merrimack Rivers by Henry David Thoreau.

Nashua, New Hampshire

Nashua is a city in Hillsborough County, New Hampshire, United States. As of the 2010 census, Nashua had a population of 86,494, making it the second-largest city in the state after Manchester. As of 2018 the population had risen to an estimated 89,246. Nashua is, along with Manchester, one of two seats of Hillsborough County.

Built around the now-departed textile industry, in recent decades it has been swept up in southern New Hampshire's economic expansion as part of the Boston region. Nashua was twice named "Best Place to Live in America" in annual surveys by Money magazine. It is the only city to get the No. 1 ranking on two occasions—in 1987 and 1998.

Silver Lake (Hollis, New Hampshire)

Silver Lake, formerly known as Long Pond, is a small lake in the town of Hollis, New Hampshire, United States. The lake was formerly surrounded by summer vacation cottages and camps, but most of these buildings have now been converted for use as year-round homes. Silver Lake State Park occupies the northern end of the lakeshore.

The lake is located on NH Route 122, north of the Hollis traffic light. The lake at its deepest is 24 feet (7.3 m) deep, and there is a deep channel running down the middle of the lake that ranges from 16 to 28 feet (4.9 to 8.5 m) at the deepest. Fish species include largemouth bass, yellow perch, sunfish, pickerel, hornpout/catfish, and a few very large common carp. The lake's depth and continual supply of cold, clean water from below can support both rainbow and brown trout.

The lake has many natural springs that provide fresh, clean water, and the small dam at the north end of the lake near the state park controls the level and output. The output flows under NH 122 and goes into Dunklee Pond which then outflows to Pennichuck Brook, a tributary of the Merrimack River.

The lake has no public boat launch, although parking at the state park can allow carry-in boats, sailboats, kayaks and other small boats. The lake has restricted hours that allow for boats to go above 10 miles per hour (16 km/h), but has no horsepower limit.

The lake has been tested for acceptable bacteria levels, and as of 2006 the State of New Hampshire had deemed the lake acceptable for swimming.

In the early 1900s when the lake was called Long Pond, it housed two dance halls, Wallace Grove and Morrills Grove. These dance halls were a very popular retreat on summer nights for many locals, some coming from as far away as Boston. Soldiers would take the train up from Fort Devens with the hope of meeting a special lady. Although both halls are long-closed, the lake remains a summer and winter retreat.
