Don Pedro Res Nr La Grange Ca reservoir
Don Pedro Res Nr La Grange Ca
Don Pedro Reservoir is a man-made lake situated in the Sierra Nevada foothills of California, about 10 miles from La Grange. This reservoir was created by the construction of the Don Pedro Dam on the Tuolumne River in 1923. It has a storage capacity of 2,030,000 acre-feet and is one of the largest water storage facilities in California. The reservoir serves as a critical source of water for irrigation, hydroelectric power generation, and municipal supply. It is also a popular recreational destination, offering activities such as fishing, boating, camping, and hiking. The reservoir receives its water from various sources, including snowmelt from the Sierra Nevada mountains, rainfall, and surface flow from the Tuolumne River. The snowpack providers are the Sierra Nevada Mountains, and the surface flow is provided by the Tuolumne River. The water from the reservoir is used for agricultural purposes in the Central Valley and in cities such as San Francisco and Modesto.

About Don Pedro Res Nr La Grange Ca
Where does the data for Don Pedro Res Nr La Grange Ca 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.
