About this reservoir

Thomas A Edison

Thomas A. Edison and his team pioneered the development of hydroelectric power generation in California's Sierra Nevada region in the early 1900s. Edison's power plants harnessed the energy of the San Joaquin River, providing electricity to the growing city of Los Angeles. To ensure water flow, Edison built dams and reservoirs, including Florence Lake and Shaver Lake. The snowpack in the Sierra Nevada mountains is a critical source of water for California, and Edison's hydroelectric facilities helped to manage this resource. The company also played a role in agricultural irrigation, with the San Joaquin River providing water to farmers in the Central Valley. Today, the area around Edison's hydroelectric plants is popular for recreational activities such as fishing and camping.

FAQ

About Thomas A Edison

Where does the data for Thomas A Edison 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.
