WaterLakeLevel currently monitors 3 verified lakes and reservoirs across California. As of this week, 3 of 3 monitored basins are recording surface elevations below their historical 25th calendar percentile, indicating localized low-water storage and selective boat ramp closures.
In California, reservoir elevations are monitored by automated telemetry stations operated by the USGS in partnership with regional river authorities and the U.S. Army Corps of Engineers. Observations are recorded in the NGVD29 vertical datum.
Recreational boaters in California should note that reservoir elevations fluctuate significantly between spring thunderstorm recharge cycles and late-summer agricultural and municipal demands. Always confirm boat ramp clearances and active wind advisories before towing watercraft.
