Jenkinson Lake reservoir
Jenkinson Lake
Jenkinson Lake is a man-made reservoir located in El Dorado County, California. It was created in 1955 by the construction of the Sly Park Dam on the Sly Park Creek. The lake covers an area of 650 acres and has a maximum depth of 97 feet. The hydrology of the lake is influenced by its location in the Sierra Nevada foothills and its proximity to the American River watershed. The lake is primarily fed by the snowmelt from the surrounding mountains and the Sly Park Creek. The lake water is used for agricultural irrigation in the surrounding area. Recreational activities on the lake include fishing, boating, camping, and hiking. The lake is a popular destination for tourists and locals alike, offering opportunities for relaxation and outdoor recreation.

About Jenkinson Lake
Where does the data for Jenkinson Lake come from?
Daily storage, pool elevation, and release rates are sourced from USGS, USBR, and USACE monitoring stations. Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.
What does the Hazard hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this reservoir, set a threshold, and you'll get a push the moment conditions cross.
