Don Pedro Reservoir reservoir
Don Pedro Reservoir
Don Pedro Reservoir is located in Tuolumne County, California, and was constructed in 1971. It is a major water storage facility in the state and provides water to agricultural, industrial, and urban areas. The reservoir is fed by surface water flow from the Tuolumne River and snowpack melt from the nearby Sierra Nevada mountains. The hydrology of the reservoir is managed by the Turlock Irrigation District, which operates the Don Pedro and La Grange dams. The reservoir has a capacity of 2.03 million acre-feet and covers an area of about 13,000 acres. It is used for multiple recreational activities, including fishing, boating, camping, and hiking. The reservoir also provides habitat for various wildlife species, such as bald eagles and black bears.

About Don Pedro Reservoir
Where does the data for Don Pedro Reservoir 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.
