Lake Crowley reservoir
Lake Crowley
Lake Crowley is a man-made reservoir located in the Eastern Sierra region of California. It was created in 1941 as part of the Los Angeles Aqueduct system and is named after the former Los Angeles Department of Water and Power Commissioner, Mulholland's assistant, and long-time employee of the LAWD, William Mulholland Crowley. The lake is fed by surface flows from the Owens River and snowpack runoff from the nearby Sierra Nevada mountains. The water from the lake is used for agricultural purposes in the Owens Valley and for drinking water in Los Angeles. The lake is also a popular recreational destination for fishing, boating, and camping. Despite controversies surrounding its creation, Lake Crowley remains an important source of water for Southern California.

About Lake Crowley
Where does the data for Lake Crowley 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.
