Crystal Sprgs Res A Dam Nr San Mateo Ca
Crystal Springs Reservoir is located near San Mateo, California, and was created by the construction of the Crystal Springs Dam in 1878. The reservoir is operated by the San Francisco Public Utilities Commission and serves as a major water supply for the Bay Area, providing up to 23 million gallons of water per day. The area is known for its unique hydrology, as it is fed by both surface flow and snowpack from the nearby Santa Cruz Mountains.

About Crystal Sprgs Res A Dam Nr San Mateo Ca
Where does the data for Crystal Sprgs Res A Dam Nr San Mateo 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.
