Gage height history

Gage height · USGS gauge 302144090052401

Reading the chart. This gauge reports gage height — the depth of water above the sensor reference point, not absolute elevation. Trends matter more than the absolute number: a falling trend means shrinking launch depth.

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. Southeast lake wind is often a thermal: light mornings building to a steady breeze by mid-afternoon, with squall lines ahead of cold fronts in the cooler months. Pop-up thunderstorms are the main hazard from June through September.
