Lake Levels

What is the purpose of the Dam and lake-levels within Saratoga Lake?

Saratoga Lake is a natural lake whose outlet is Fish Creek. Water levels are controlled by a privately owned dam on Fish Creek that historically served milling and later hydroelectric purposes.  In current practice, the dam’s operational role is limited: it is used to manage seasonal lake levels primarily to protect wildlife habitat and help control aquatic vegetation along the shoreline, with levels intentionally lowered in late October and more weather-dependent in winter.  SLPID works under an agreement with the dam owners to help regulate these levels, but the structure is not operated as a large, multipurpose flood-control reservoir.

By contrast, Great Sacandaga Lake is not a natural lake; it is a reservoir created in 1930 by the Conklingville Dam on the Sacandaga River.  The primary purpose of that dam and reservoir was regional flood control on the Hudson and Sacandaga rivers, in response to severe historic floods such as the 1913 flood that inundated Troy and other downstream communities.  The state created the Hudson River Regulating District specifically to impound water in the upper Hudson watershed to prevent downstream flooding and to allow managed releases during droughts.  Great Sacandaga Lake therefore has a statutory flood-control mandate and very large storage capacity that Saratoga Lake does not have.

Saratoga Lake does not have a similar dam or mandate because it was never converted into a regulated reservoir by the Hudson River Regulating District or a similar entity. The Fish Creek dam is a relatively small, privately owned outlet structure, not a state-created flood-control dam.  Creating a Sacandaga-style flood-control reservoir at Saratoga Lake would require dramatically higher dams and much greater drawdowns, with major impacts on shoreline properties, infrastructure, and ecosystems— for which there is no legal or institutional mandate comparable to the Regulating District’s authority over the Sacandaga.

For comparison, several natural lakes near Saratoga Springs face similar high-water challenges without a large, actively managed dam. Moreau Lake (Moreau Lake State Park) and Round Lake are natural lakes with no major flood-control dam or formal water-level operating regime like Great Sacandaga, yet they still experience significant seasonal and storm-driven fluctuations.  Ballston Lake is a natural lake with no controllable dam (DEC lists its dam classification as “0,” meaning no dam), and local monitoring shows it was above flood stage for 151 days (42% of the year) in one recent 12-month period, with residents reporting erosion, property impacts, and recreational issues from high water.  These examples show that high lake levels and dock/boat challenges are common on natural lakes in our area, driven by precipitation and limited outlet capacity, regardless of whether a large, regulated dam exists.

Flood risk around Saratoga Lake is also managed through federal and state floodplain regulations. Much of the lakeshore lies within FEMA’s Special Flood Hazard Area (the mapped 100-year floodplain).  Under the National Flood Insurance Program, any new construction, substantial improvement, or substantially damaged structure in that area must meet strict standards: the lowest floor must be elevated to at or above the Base Flood Elevation, plus an additional 2 feet for residential structures in New York.  These requirements are enforced through local floodplain development permits, and development in a regulatory floodway must demonstrate that it will not increase flood levels.

With respect to climate change and more intense rain events, SLPID, the dam owners, Homeland Security and Emergency Services, Saratoga County Emergency Services, and hired engineers have previously examined options such as dredging near the dam to increase flow capacity. That work concluded that such measures would not meaningfully improve dam operation and are not financially prudent, so they have not been pursued.
