Lake elevation history
Lake or reservoir elevation · USGS gauge 01470870
Reading the chart. This gauge reports absolute lake surface elevation in feet above its datum (typically NGVD29 or NAVD88). Sustained drops of more than a foot can expose shallow launch ramps and shoal areas.
Water levels respond to dam operations, irrigation drawdown, snowmelt, and recent rainfall. For launch decisions, combine the trend here with the wind forecast — low water plus strong wind makes steep, tired ramps.

Water level data comes from the USGS gauge above; wind is modeled for the lake’s coordinates by Open-Meteo. Always confirm conditions locally before launching — shorelines, ramps, and trees can all change what you feel on the water. In the Northeast, the strongest lake wind usually arrives with cold fronts and the northwest flow behind them. Long, narrow lakes channel wind along their axis, and a sunny afternoon can double a light morning breeze on big water.
