About this reservoir

Spaulding Lake

Spaulding Lake, located in California, is a man-made reservoir with a rich history. It was created in the 1960s to provide water for the surrounding areas, including Sacramento, Yuba, and Placer counties. The lake is fed by the Yuba River and a series of canals and ditches. The hydrology of the lake is closely monitored to ensure a sustainable water supply. The lake relies on snowpack from the Sierra Nevada Mountains and surface water flows from the Yuba River for its water supply. The lake is used for agricultural purposes, including irrigation for crops such as rice, and also provides recreational opportunities such as boating and fishing. The lake and its surrounding areas are home to a variety of wildlife, including bald eagles, ospreys, and black bears.

FAQ

About Spaulding Lake

Where does the data for Spaulding 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.
