Hudson River Dams

List of Dams on the Hudson River

The Hudson River is home to several major dams which have been built to harness the power of its flow. The following is a list of some of the more important ones:

Croton Dam

Constructed in 1906, the Croton Dam is located on the Croton River near Peekskill and provides a reservoir for New York City’s drinking water.

Abanakee Dam

Constructed in 1922, the Abanakee Dam is located on the Beaver Kill near Woodstock and is used for hydroelectric power generation.

Gilboa Dam

Constructed in 1927, the Gilboa Dam is located near Schoharie and provides a reservoir for New York City’s drinking water.

Conklingville Dam

Constructed in 1930, the Conklingville Dam is located on the Sacandaga River and is used for hydroelectric power generation.

Hudson-Athens Lighthouse Dam

Constructed in 1938, the Hudson-Athens Lighthouse Dam is located near Hudson and controls water flow on the Hudson River.

Tomhannock Dam

Constructed in 1942, the Tomhannock Dam is located on Tomhannock Creek near Troy and provides a reservoir for New York City’s drinking water.

Ice Harbor Dam

Constructed in 1957, the Ice Harbor Dam is located near Hudson Falls and controls water flow on the upper Hudson River.

Troy Dam

Constructed in 1967, the Troy Dam is located near Troy and provides a reservoir for New York City’s drinking water.

Hudson River Dams Water Levels

The water levels in the Hudson River Dams can vary significantly based on their position and seasonal changes. Usually, the minimum depths range anywhere between 4-17 feet, depending on the total reservoir capacity and tidal movement.

During periods of heightened flow, the liquid may even exceed 17 feet. Conversely, during times of low streamflow, the pool levels could sink down to only 4 feet.

Additionally, many of the dams also regulate water flow depending on the needs of downstream communities around the Hudson River. This helps ensure that enough water is available for recreational activities, irrigation, and hydroelectric generation.

Why Are There Dams on the Hudson River

The Hudson River is home to a multitude of vital dams that provide electricity, improved navigation and transportation, and better control against flooding and irrigation, in addition to recreational activities such as fishing and boating.

These structures are essential for the flourishing of cities along their banks, providing necessary water resources that sustain their growth. The dam system is also integral to the health of the Hudson River ecosystem and continues to play an important role in our lives today.

Largest Dams on the Hudson River

At an impressive height of 221 feet, the Gilboa Dam in Schoharie County, New York is the largest dam in terms of volume capacity, with a whopping 187,000 acre-feet for water storage. It was constructed in 1927 primarily as a flood control measure and also to provide recreation and hydroelectric power.

The Naples Dam in Ontario County, New York is the second biggest; standing 130 ft. tall and storing up to 18,000 acre-feet of water. It was erected in 1926 with similar purposes: flood control, recreation, and hydroelectric power.

The Conklingville Dam in Saratoga County is the third greatest dam on the Hudson River. It stands at 114 ft and is able to store up to 8,800 acre-feet of water.

Built in 1912, it serves for flood control, recreational activities, hydroelectric power generation, and irrigation.

How Many Dams Are on the Hudson River and Its Tributaries?

The Hudson River and its tributaries are home to a plethora of dams, used for various objectives ranging from power production to flood prevention.

According to the US Army Corps of Engineers, there are over 70 active dams situated along the length of this waterway; not including those that have been abandoned or put out of service.

Of these functional structures, many are employed for hydropower, flood protection, and water provision. While some work to generate electricity, others serve as a shield against torrential rainfall that could threaten homes and businesses.

The New Croton Dam is the most prominent of these installations, supplying NYC with drinking water. Furthermore, further-upriver dams supply ample amounts of water to cities and towns in the Hudson Valley.
