Lake Piru reservoir
Lake Piru
Lake Piru is situated in Ventura County, California, and it was formed in 1955 with the construction of the Santa Felicia Dam. It is a reservoir that is fed by the Piru Creek, which originates in the San Emigdio Mountains. The Piru Creek provides the lake with its primary source of surface flow, and the area also receives water from snowpacks in the mountains. The lake is used for both agricultural and recreational purposes, with agricultural water being released downstream to irrigate farms, and recreational activities like boating and fishing are popular. The lake is also home to a diverse range of flora and fauna, including birds, fish, and aquatic plants. In recent years, the lake has faced challenges with drought and low water levels, leading to concerns about its long-term sustainability.

About Lake Piru
Where does the data for Lake Piru 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.
