About Prosser Creek Reservoir
Prosser Creek Reservoir is a reservoir on the Prosser Creek in California, operated by U.S. Bureau of Reclamation. Its full summer pool sits at 5741.2 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Prosser Creek Reservoir's water level
"Full pool" is the elevation U.S. Bureau of Reclamation targets when Prosser Creek Reservoir is completely filled — 5741.2 feet above sea level. That is the elevation Prosser Creek Reservoir reaches at the top of a good runoff year, not a level it is held at. Reservoirs like this one fill from winter storms and snowmelt and are then drawn down deliberately through the dry season, so the gap between today's reading and 5741.2 ft is normally the season rather than a shortage. Judge it against the same week last year, not against full.
Prosser Creek Reservoir climbs through winter and spring as storms and snowmelt come off the mountains, peaks around late spring, and falls steadily through summer and autumn as water goes downstream and flood space is reopened for the next winter. A wet winter can raise it dramatically; the low point almost always lands in autumn regardless.
The recent high and low above are drawn from the published history available for Prosser Creek Reservoir, so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
