Folsom Lake Water Level: 2022 Watch
Updated: Apr 25
Because of the ongoing drought, many Sacramento area recreational boaters are concerned about the Folsom Lake water level falling low enough at some point in 2022 to trigger a vessel speed limit reduction to 5 MPH.
Temporary speed reductions are ordered by the State of California Department of Parks and Recreation.
This year's relative water levels for Folsom Lake
Below is a three-year comparison of the reservoir's water levels. The information is sourced from the California Department of Water Resources.
Fortunately, the heavy foothills rain and Sierra snow in November and December of 2021 raised Folsom Lake's water level to 427 feet — up from an October 21st low for the year of 370.28 feet.
Folsom Lake's full pool level is 466 feet of elevation. The full pool level is represented by the bold green line in the following chart.
As you can see by the bold blue line in the chart, 2022 has started out above 2020 water levels. (In case the above-embedded chart doesn't render in your browser, you can view the chart here.)
The bold red line represents the cutoff point for boat speeds above 5 MPH. The blue line is updated daily, so please check back to see the lake's current water level.
Unless the cutoff level changes, as long as the blue line remains above the red line, you can enjoy sports such as wakeboarding and waterskiing on Folsom Lake.
How deep is Folsom Lake?
The above numbers may make you wonder how deep Folsom Lake is. A 2005 survey measured the minimum bottom of Folsom Lake to be about 190 feet of elevation.
This means that at full pool level, the deepest part of the reservoir is 466 - 190 = 276 feet.
When the Folsom Lake Water level is at the 5 MPH cutoff speed for vessels, the deepest part of the reservoir is 400 - 190 = 210 feet.
Additional Folsom Lake facts
Folsom Lake is a reservoir located in the Sierra Nevada foothills east of Sacramento, California. The lake is fed by the American River. It has a maximum pool capacity of 977,000 acre-feet.
Folsom is the largest reservoir in the Sacramento-San Joaquin River Delta and provides water for the city of Sacramento and surrounding areas.
The lake was created in 1955 with the construction of the Folsom Dam on the American River. The dam was built to provide flood control — and water for irrigation and municipal water supplies.
The City of Folsom was named in honor of Joseph Libby Folsom, its founder. Both the lake and the dam adopted the city's name.
