The Housatonic River (// HOOS-ə-TON-ik) is a river, approximately 149 miles (240 km) long,  in western Massachusetts and western Connecticut in the United States. It flows south to southeast, and drains about 1,950 square miles (5,100 km2) of southwestern Connecticut into Long Island Sound. Its watershed is just to the west of the watershed of the lower Connecticut River.
Inspired by the river during his honeymoon, the American classical music composer Charles Ives wrote "The Housatonic at Stockbridge" as part of his composition Three Places in New England during the 1910s, drawing his text from a poem of the same name by Robert Underwood Johnson. The town of Stockbridge is located in southwestern Massachusetts. The river enters Stockbridge on the east side of town before turning south toward Connecticut.
From about 1932 until 1977, the river received PCB pollution discharges from the General Electric plant at Pittsfield, Massachusetts. Although the water quality has improved in recent decades, and remediation has occurred, the river continues to be contaminated by PCBs. Additional remediation is planned.
The United States Navy named a ship for the Housatonic River. The USS Housatonic has the distinction of being the first ship in history to be sunk by a submarine, the confederate vessel CSS H.L. Hunley.
Covered wooden bridges
Three wooden covered bridges cross the Housatonic River. Two are in Connecticut: one known as Bull's Bridge, which spans the river between Gaylordsville and Kent, and another at Cornwall, known as the West Cornwall Covered Bridge. Reinforced with present-day materials, both bridges carry normal vehicle traffic, albeit in only one direction at a time. The third bridge, located in Sheffield, Massachusetts, was destroyed by fire and rebuilt in 1998; it is now open only to foot traffic.
Ecology and Wildlife
Historically, the Housatonic River, and its Naugatuck River tributary, hosted the southernmost Atlantic salmon (Salmo salar) spawning runs. The Salmon Creek tributary of the Housatonic River may have been named for this salmonid, which can reach up to 30 pounds (14 kg).
Watershed and Course
The Housatonic River watershed drains 1,948 square miles (5,050 km2) in western Connecticut and Massachusetts and eastern New York. The Housatonic rises from four sources in far western Massachusetts in the Berkshire Mountains near the city of Pittsfield. It flows southward through western Massachusetts through the Berkshires and into western Connecticut, and empties into Long Island Sound between the towns of Stratford and Milford.
The river's total fall is 1,430 feet (440 m) (959 feet (292 m) from the confluence of its east and west branches) to Long Island Sound. Its major tributaries in Massachusetts are (heading downstream) the Williams River (in Great Barrington), Green River and Konkapot River (in Ashley Falls). Crossing south into Connecticut, the Housatonic's major tributaries are the Blackberry River (in Canaan), Salmon Creek (below Falls Village), Ten Mile River (above Gaylordsville but originating in New York), Still River (south of New Milford), Shepaug River (at the Bridgewater and Southbury border), Pomperaug River (at Southbury), and Naugatuck River (in Derby). The Naugatuck River is the Housatonic's largest tributary with a contributing watershed of 312 square miles (810 km2).
Five dams impound the river in Connecticut to produce hydroelectricity: the Falls Village, Bulls Bridge, Shepaug, Stevenson and Derby dams. The last three dams form a chain of lakes: Lake Lillinonah, Lake Zoar and Lake Housatonic, from New Milford south to Shelton.
The Housatonic River is a popular whitewater paddling destination beginning at Falls Village, Connecticut and continuing to Gaylordsville. Most of the river is quickwater and Class I whitewater with long sections of Class II-III whitewater. A deadly and extreme Class VI resides at Great Falls in Canaan (Falls Village) and is most likely not able to be paddled. The most dangerous and difficult section that is navigable is by Bulls Bridge, with Class V whitewater.
There are several minor and major dams along the river that form lakes. Most notable are two lakes in Connecticut, Lake Zoar, which borders Monroe, Newtown, Oxford, and Southbury, and Lake Lillinonah. Both lakes are major water-sport recreation outlets for the surrounding towns.
Two of the three lakes formed by the dams are used for rowing by clubs, schools, and to host regattas. Lake Lillinonah is used by the GMS Rowing Center and is host to the GMS Regatta. Lake Housatonic is used by the Yale University Crew Team and the New Haven Rowing Club and is host to the Derby Sweeps & Sculls and the Head of the Housatonic.
The Housatonic River is also a popular fly fishing destination. Fly fishing on the Housatonic River (which is strictly catch and release) has been compared with western rivers and is among the finest for trout in the eastern United States. The most popular area for fly fishing is in Litchfield County, Connecticut between the dam at Falls Village and the Cornwall Bridge.
The Appalachian Trail follows the river along this section from the Bulls Bridge covered wooden bridge near Kent to Falls Village.
