About Trinity Lake
Trinity Lake is a reservoir on the Trinity River in California, operated by U.S. Bureau of Reclamation. Its full summer pool sits at 2370 ft above sea level. Live water levels come from California's Department of Water Resources (CDEC) and update daily.
Understanding Trinity Lake's water level
"Full pool" is the elevation U.S. Bureau of Reclamation targets when Trinity Lake is completely filled — 2370 feet above sea level. Reservoirs like Trinity Lake fill from winter storms and spring snowmelt toward 2370 ft, then get drawn down through the dry season to supply cities and farms — so sitting below full pool by late summer is expected, not a warning sign.
Expect Trinity Lake to climb through winter and spring, peak around early summer, and fall through the dry summer and autumn as water is released downstream. A wet, snowy winter can raise it dramatically; a drought year can leave it low well into the next season.
The recent high and low above are drawn from the published history available for Trinity Lake, 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.
