About Lake Isabella

Lake Isabella is a reservoir on the Kern River in California, operated by U.S. Army Corps of Engineers. Its full summer pool sits at 2605.5 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.

Understanding Lake Isabella's water level

"Full pool" is the elevation U.S. Army Corps of Engineers targets when Lake Isabella is completely filled — 2605.5 feet above sea level. That is the elevation Lake Isabella 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 2605.5 ft is normally the season rather than a shortage. Judge it against the same week last year, not against full.

Lake Isabella 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 Lake Isabella, 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.
