About this reservoir

Florence Lake (Sce)

Florence Lake is a reservoir in California that was created in 1914 by the Southern California Edison company as part of a hydroelectric power project. The lake is fed by several rivers and streams, including the San Joaquin River, and is an important source of water for irrigation in the region. Snowmelt from the surrounding mountains also contributes to the lake's water supply. The area around Florence Lake is popular for recreational activities like fishing, hiking, and camping. The lake is also home to several species of fish, including rainbow trout and brown trout, and is stocked annually by the California Department of Fish and Wildlife. The lake's hydroelectric power plant generates electricity for Southern California Edison's customers.

FAQ

About Florence Lake (Sce)

Where does the data for Florence Lake (Sce) 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.
