Lake George Water Level: Current and historical data
Jumping into a cool Lake George on a hot summer day is one of the joys of the season.
  • Can you drink the water in Lake George?
    Absolutely. Many people have historically drawn drinking water from Lake George and many continue to do so, according to the LGA’s Watershed Data Atlas. Lake George is designated a Class AA-Special water body in New York State. This designation prohibits the disposal of floating solids, oil, sludge, toxic wastes, other “deleterious” substances or wastes, heated liquids, sewage, or other waste effluents in the water. Learn more about Lake George being drinking water here.
  • Can I take a bath in the Lake, or wash my dishes or clothing in the Lake?
    No one is allowed to use any soaps or detergents in Lake George, as that will damage the water quality. The Lake George Park Commission, in its role as state regulatory agency of the Lake, prohibits such acts. See the Park Commission’s Water Quality Protection rules here.
  • How long does it take the water to reach the outflow?
    Lake George flows south to north but has a significant retention time. It takes about 8 years for the water to reach the outflow at the northern end of the lake.
  • How many mountains surround Lake George?
    A variety of mountains surround Lake George: Prospect, Tongue, Shelving Rock, Buck, Little Buck, Sleeping Beauty, Pilot Knob, French, Black, Cat, Thomas and Cook.
  • 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.


  • How do I register my boat and/or dock?
    Boating on Lake George: Please ensure your boat is Clean, Drained and Dry before launching on Lake George.

    State Law requires that, in addition to registration required by the NYS Department of Motor Vehicles, any vessel 18 feet or longer and any vessel mechanically propelled by 10 h.p. or greater, must register with the Lake George Park Commission and display a registration decal. The Lake George Park Commission also has a dock registration program. Call the Lake George Park Commission at 518-668-9347 or visit their website here.

  • Do I need to get my boat inspected before I can launch into Lake George?
    Yes. You need to ensure that your trailered boat is “Cleaned, Drained and Dry” before being launched into Lake George, or it will need to be cleaned. All trailered boats are required to be inspected and possibly decontaminated before being allowed to launch. The inspections are done by the Lake George Park Commission to ensure that invasive species are not being carried into Lake George. Inspections and any decontamination are performed at no cost to the boater. The Lake George Association has been contributing $30,000 a year since the program’s inception. It was developed from the LGA’s Lake Steward program which was a voluntary inspection program . For more information, please see the Lake George Park Commission’s Boat Inspection website.
  • Are there public boat launches on Lake George?

Camping Best Practices

  • How do I reserve a state campsite on the islands or state campground?
    Please visit the NYS Department of Environmental Conservation or Reserve America web pages or by calling 1-800-456-CAMP to find information about the islands on Lake George. You may also contact the NYS DEC Camping facilities directly at Long Island: 518-656-9426; Glen Island: 518-644-9696; Narrows: 518-499-1288.
  • When I rent or camp, what can I do to help protect the Lake?
    • Ensure that your boat, kayak, canoe and other water craft are “Cleaned, Drained and Dry” before before you put them in the lake. Trailered boats are now required to be inspected before being allowed to launch. The inspections are done by the Lake George Park Commission to ensure that invasive species are not being carried into Lake George. Inspection and decontamination are performed at no cost to the boater. The Lake George Association is contributing $30,000 to pay for part of the program in 2015. For more information, please see the Lake George Park Commission’s Boat Inspection website.
    • Keep oil and gas out of the lake – Use oil absorbent pads in the bilges; clean the boat away from the water. Keep motors properly tuned. Learn about Lake-Friendly Boating here.
    • Do not bathe in the lake – Soap contains phosphorus, and threatens water quality.
    • Don’t feed the ducks – They are a major source of parasites (swimmers’ itch) and phosphorus.
    • Keep chemicals out of the lake – don’t use chemical toilet cleaners, or put toxics down the drain. All can end up in the lake. Buy only environmentally friendly cleaning products.
    • Obey all boating safety regulation.
    • For further information, contact the Lake George Island Campers Association.

    Feeding Ducks & Geese

    • Why can’t I feed the ducks and Canada Geese?
      Ducks, Geese, and gulls have a natural survival rhythm. Our interruptions of their routine creates a destructive cycle which breaks the animals of their instinctual habits. By feeding waterfowl things like popcorn, bread, crackers and potato chips, we make them dependent on our handouts and provide them with less nutritious foods than they naturally would find for themselves. Learn more about nuisance wildlife here.


    • What fish are in Lake George?
      Lake George has a “two-story” fishery; both warm water fish, such as perch, bass, and sunfish and cold water fish, such as lake trout and salmon, are found in the Lake. There are 36 fish species in the Lake George watershed. Learn more about the fish of Lake George here.
    • Do I need a license to fish in Lake George?
      Yes, persons 16 or over must have a license. They can be purchased at local bait shops and town and village offices.
    • When do ice shanties have to be removed from the ice surface?
      NYS/DEC requires all shanties must be removed from the ice surface no later than March 15th.

    • Can I fertilize my lawn? 
      The Dishwasher Detergent and Nutrient Runoff Law prohibit the use of phosphorus lawn fertilizer unless establishing a new lawn or a soil test shows that the lawn does not have enough phosphorus, prohibit the application of lawn fertilizer on impervious surfaces and require pick up of fertilizer applied or spilled onto impervious surfaces, prohibit the application of lawn fertilizer within 20 feet of any surface water except: where there is a vegetative buffer of at least 10 feet; or where the fertilizer is applied by a device with a spreader guard, deflector shield or drop spreader at least three feet from surface water, prohibit the application of lawn fertilizer containing nitrogen, phosphorus, or potassium between December 1st and April 1st, and requires retailers to display phosphorus containing fertilizers separately from non-phosphorus fertilizers and to post an educational sign where the phosphorus fertilizers are displayed. Learn more on the DEC website here.
    • Can I cut trees on my property or shoreline?
      Contact The Adirondack Park Agency at 518-891-4050. Generally, there are no requirements for the harvesting of trees on nonshoreline parcels unless you plan to clear-cut more than 25 upland acres or 3 wetland acres, or the property is located in a Designated River Area. However, cutting of trees in preparation for a project requiring a permit may not begin until the permit is obtained; tree removal is part of the project review process. In addition, there are permit requirements for the construction of woods roads or skid trails through wetlands. Along shorelines, cutting is limited to the following: Within 6 feet of shore, not more than 30 percent of the shoreline may be cleared of vegetation (bushes and trees) on any one lot. Within 35 feet of shore, not more than 30 percent of trees in excess of 6 inches in diameter at 4.5 feet above the ground may be cut over a 10-year period.
