About this reservoir

Oroville Dam

Oroville Dam, located in California, is the tallest dam in the United States and plays a significant role in the state's water supply. The dam was completed in 1968 and provides hydroelectric power, flood control, and irrigation water to the surrounding agricultural areas. The dam's reservoir is fed by the Feather River, which in turn is supplied by both surface flow and snowpack from the Sierra Nevada mountains. The reservoir also serves as a recreational area for boating, fishing, and camping. However, in 2017, the dam experienced significant damage during heavy rains, leading to concerns about its safety and necessitating emergency repairs. Despite these concerns, Oroville Dam continues to be an essential component of California's water infrastructure.

FAQ

About Oroville Dam

Where does the data for Oroville Dam 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.
