Gage height history
Gage height · USGS gauge 09429495
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. In the Southwest, wind is a terrain story: desert basins run strongest in spring afternoons, canyon mouths funnel gusts far out onto the water, and monsoon storms can build fast after midday in summer. Mornings are the calm, predictable window.
