About this reservoir

Rubicon Lake

Rubicon Lake is a beautiful alpine lake located in the Sierra Nevada Mountains of California. This lake has a rich history and is an important source of water for the surrounding area. The lake's hydrology is heavily influenced by snowpack, which provides the majority of its water supply. The Rubicon River flows into the lake, and the lake's outflow feeds into the Middle Fork of the American River. The Rubicon Lake area is popular for hiking, fishing, and camping, and it is also used for agriculture. The lake provides water for irrigation of nearby crops, and the surrounding forests are used for timber production. Overall, Rubicon Lake is an important resource for the local community and a beautiful destination for visitors to the area.

FAQ

About Rubicon Lake

Where does the data for Rubicon Lake 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.
