Choke Canyon Reservoir level history
This site counts a reservoir as full on a day its storage is at or above 95% of the dam's normal storage (National Inventory of Dams). Many reservoirs rarely reach 100%, even in wet years, because operators release water for irrigation, power or flood control before they fill, so this site treats 95% as full. Highs and lows are daily readings in the published data, not official records. Source: USGS daily data.
