Notes

  • The lake has never been this high (or low) before... really? view Historical Levels
  • Mean High Water Level – 715.3'
    Official value which was defined many years ago from historical high water measurements and is referred to as the National Tidal Datum Epoch. This is a key point for all lake shore property owners which defines boundaries.
  • Low Water Level - 712.5’
    The property boundary between the State of NY and shoreline property owners.

    The New York State DEC regulates the use and development of land between the low water level (712.5’) and the mean high water level (715.3’), even when this property is privately owned.
  • New gates were completed in November of 1993
  • Top of dam: 716.04'
  • 100 Year Flood Level - 720.8'
    Flood level that has a 1% chance of occurring each year, used by most Federal and State agencies, including FEMA, for flood plain management and the National Flood Insurance Program.
  • Miniumum Outflow
    Minimum allowed water outflow is 20 cubic feet per second (CFS), to allow adequate Penn Yan wastewater treatment plant discharge dilution.
  • Normal Maximum Outflow
    Normal maximum allowed water outflow is limited to 1,000 cubic feet per second (CFS), to minimize any potential downstream damage. Exceeding this amount should only happen during high water emergency periods, requiring KLOC to declare Condition B, which is a non-failure emergency condition.
  • For more details on outflow read how total discharge is calculated.
  • All lake level values are shown in feet above sea level per NGVD29 datum.

Lake level readings are obtained from the recording device installed at the Penn Yan Water Treatment Plant, updated every two hours.  The curves on the chart reflect the last reading of every day.

When the lake level raises above the height of the dam at 716 ft., all gates are closed and water spills over the top of the dam with no ability to regulate the outflow.

The KLOC (Keuka Lake Outlet Compact), an inter-municipal corporation consisting of senior leaders from the eight municipalities around the lake shoreline, has ultimate responsibility for management of water levels and upkeep of the outlet gates.  Representatives from the KLA attend all KLOC meetings and provide input in the best interest of their members.  For more information regarding lake level management, please refer to the Keuka Lake Water Level Management page shown below under related pages.
