  • What is a watershed? 
    A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. In the continental US, there are 2,110 watersheds; including Hawaii Alaska, and Puerto Rico, there are 2,262 watersheds (USGS).
  • How large is the Lake George Watershed?
    The Lake George watershed area — including every place where water can drain into Lake George — is 233 square miles, or more than two-thirds the size of New York City.
  • How is Lake level managed?
    The lake level is managed at an outlet dam (the “A Mill” dam) and a penstock (a pipe ten feet in diameter) located at the hydroelectric power plant at the entrance of the La Chute River in Ticonderoga. The dam, built in 1903 and currently owned by the NYS Department of Environmental Conservation, is located about three-quarters of a mile beyond the natural rock dam at Ticonderoga. When the water level is high, the dam and penstock offer a means of discharging the excess water into the river and out of the Lake. At present, the Lake George Park Commission is responsible for managing the lake level under an agreement with the NYS Department of Environmental Conservation in cooperation with La Chute Hydro, Inc. The lake level typically varies between 319 and 320 feet above sea level with flood stage at 320.5 ft. Lake level is monitored in real time by the US Geological Survey through a gauge station north or Rogers Rock. Official records of lake levels on Lake George date back to July of 1913.

The inspections are done by the Lake George Park Commission to ensure that invasive species are not being carried into Lake George.
