About this reservoir

Pyramid

Pyramid Lake is located in the Angeles and Los Padres National Forests in California. It is a reservoir formed by Pyramid Dam on Piru Creek, a tributary of the Santa Clara River. The lake was created in 1972 and is a key source of water for Southern California. The region receives most of its water from snowpack and surface flow from the Sierra Nevada Mountains. The lake also serves as a hub for agricultural irrigation and recreational activities such as boating and fishing. The lake's recreational areas are popular for camping, picnicking, and hiking. Pyramid Lake has been a significant cultural site for Native American tribes for thousands of years and is considered a sacred site. Today, the lake remains an important resource for the people and wildlife of California.

Plan around the weather

Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

FAQ

About Pyramid

Where does the data for Pyramid 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.
