Live Lake Conditions
Keuka Lake is a Y-shaped lake in the Finger Lakes region of New York State, approximately 20 miles long with a surface area of 11,584 acres. Keuka.org provides real-time monitoring of lake conditions from a network of private water quality sensors deployed around the lake.
Our sensor network continuously measures water temperature, lake surface elevation, turbidity, and total dissolved solids at multiple locations. Weather stations around the lake report air temperature, wind speed and direction, humidity, solar radiation, and precipitation.
Live Video Streams
Watch Keuka Lake in real-time through our live video cameras. Streams are available from Branchport at the west branch, Hammondsport at the south end, and Penn Yan at the north end of the lake. Each camera provides a unique perspective of lake conditions, weather, and seasonal changes throughout the year.
Water Level Tracking
Keuka Lake's water surface level is measured daily using an ultrasonic sensor and reported as elevation above sea level in feet. The lake level is managed by the Keuka Lake Outlet dam in Penn Yan, with target levels that vary by season to balance recreational use, flood control, and ecological health. Historical water level data is available from 2021 to present, allowing year-over-year comparison of lake levels.
Weather and Forecasts
Current weather conditions at Keuka Lake are collected from multiple weather stations around the shoreline, providing hyperlocal data including air temperature, wind speed and direction, barometric pressure, humidity, precipitation, and solar radiation. Multi-day forecasts are available for communities around the lake including Hammondsport, Penn Yan, and Branchport.
Water Quality Observation Network
The Keuka Lake water quality observation network is a community-driven effort to monitor the health of the lake. Sensors measure water temperature at the surface and at depth, turbidity (water clarity), and total dissolved solids. This data supports scientific understanding of the lake's thermal patterns, mixing cycles, and overall water quality trends.
Lake Water Balance and Evaporation
Keuka.org tracks the daily water budget of Keuka Lake, calculating inputs from precipitation and watershed runoff against outputs from evaporation and outlet discharge at Penn Yan. Evaporation is calculated using the Penman open-water equation, incorporating solar radiation, air and water temperature, humidity, and wind speed from our sensor network. The lake's 176 square mile watershed contributes runoff from streams including Keuka Inlet and Cold Brook.
Community Events
Discover events happening around Keuka Lake throughout the year. From summer concerts and wine trail festivals to winter activities, the Keuka Lake community calendar keeps you connected to everything happening in Hammondsport, Penn Yan, Branchport, and the surrounding Finger Lakes region.
About Keuka Lake
Keuka Lake, also known as "Crooked Lake" for its distinctive Y-shape, is one of eleven Finger Lakes in central New York. The lake reaches a maximum depth of 186 feet with an average depth of 101 feet. It is one of only two lakes in North America that is Y-shaped, with a bluff at the fork separating the northwest branch (Branchport) from the southwest branch (Hammondsport). The lake is renowned for its clean water, excellent fishing, and the surrounding Keuka Lake Wine Trail, one of the oldest wine trails in the United States.
