It is a popular local recreation spot. Many summer camps are located along it, as well as a large private campground. Many residents from Chelsea Cove also use the lake recreationally.

It is an irregular rounded shape, with a 116-acre (47 ha) surface area, located near the town's southwestern border with East Fishkill. High unnamed hills rise to 820 feet (250 m) to its northeast, 500 feet (150 m) above the lake. The unincorporated hamlet of Sylvan Lake is located to its southeast and east. Dutchess County Route 10 runs northwest from the hamlet along the lakeshore, providing access to the nearby Taconic State Parkway via the NY 82 state highway at Arthursburg.
To the southwest are lower hills. The lake's unnamed outlet brook flows at first northward through a 91-acre (37 ha) wetland between two smaller hills at that end but soon turns southward, carrying the drainage from the lake and its 0.81-square-mile (2.1 km2) basin south a few miles to Fishkill Creek. From there it reaches the Hudson River at Beacon.
The lake is located adjacent to the Chelsea Cove housing complex and all its residents are permitted access to the lake. There is a small beach with a small area to wade in before it drops off into much deeper waters. Sylvan Lake Beach Park, a privately operated campground, is located along another shore. The remainder of the 1.8-mile (2.9 km) shoreline is owned by private residences and summer camps.
The lake is 140 feet (43 m) deep, the deepest in Dutchess County. Formerly a quarry used for mining, the slope is very steep and reaches maximum depth quickly near the center of the lake. The thermocline in the lake reaches about 40 degrees F. To scuba dive in the lake, advanced open water certification is needed. Equipment such as 7mml full body wetsuits including gloves and hood are necessary as are lights due to the murkiness of the water.
The campground and camps have facilities for swimming in the lake near its shore. Boating is permitted on the lake as long as gasoline-powered engines are not used. Diving is also permitted with advanced open-water certification due to the lake's depth.
Angling, from either boats or the shoreline, is also permitted. Fishermen must have a valid New York state license. The lake has a bass population in its warmer areas, and the state Department of Environmental Conservation stocks it with 1,700 brown trout fry every spring. Special fishing regulations apply since the lake is also a popular ice fishing spot in winter. Trout may be taken all year round; there is no minimum size and up to five fish a day may be taken. Some anglers have taken trout as large as 10 pounds (4.5 kg).
Dennis Joseph "Dan" Brouthers (; May 8, 1858 – August 2, 1932) was an American first baseman in Major League Baseball whose career spanned the period from 1879 to 1896, with a brief return in 1904. Nicknamed "Big Dan" for his size, he was 6 feet 2 inches (1.88 m) and weighed 207 pounds (94 kg), which was large by 19th-century standards.Recognized as the first great slugger in baseball history, and among the greatest sluggers of his era, he held the record for career home runs from 1887 to 1889, with his final total of 106 tying for the fourth most of the 19th century. His career slugging percentage of .519 remained the Major League record for a player with at least 4,000 at bats until Ty Cobb edged ahead of him in 1922. At the time of his initial retirement, he also ranked second in career triples (205), and third in runs batted in (1,296) and hits.A dominant hitter during the prime of his career, he led (or was in the top of) the league in most offensive categories, including batting average, runs scored, runs batted in (RBI), on-base percentage and hits. He led the league in batting average five times, the most by a 19th-century player, and his career .342 batting average still ranks ninth all-time. Brouthers is one of only 29 players in baseball history to date who have appeared in Major League games in four decades.
He was also an active players' union member, and was elected vice president of the Brotherhood of Professional Base Ball Players. Brouthers was elected to the Baseball Hall of Fame in 1945 by the Veterans Committee.Sylvan Lake, New York
Sylvan Lake is a hamlet in the Town of Beekman, Dutchess County, New York. It is named after the lake it sits on, which was formed during the Ice Age.The early Indians originally named it "poughquag" which means "round body of water". A smaller lake known as Hidden Lake is where Daniel Delany, in the late 19th century, discovered iron ore and made his fortune. He eventually bought the adjacent property which was the entire shoreline of Sylvan Lake and rebuilt St. Denis Church for the town. Some iron ore mining also took place along the shores of Sylvan Lake in the early 1930s and some of these retainer wall pilings are still standing and can be clearly seen from a boat. When the mine was filled with water, construction equipment and mining tools were left on the bottom, and are present today.
