Olivenhain Reservoir reservoir
Olivenhain Reservoir
Olivenhain Reservoir, located in San Diego County, California, was constructed in 2003 by the city of Encinitas. The reservoir's primary purpose is to store imported water from the Colorado River and Northern California for use by the city's residents. The reservoir has a capacity of 24,000 acre-feet and is primarily filled by water from the San Diego County Water Authority. Additionally, the reservoir receives water from local surface flow and snowpack providers, including the San Dieguito River and the San Elijo Lagoon. The reservoir also supplies water for agricultural use in the surrounding area. Recreational activities, such as fishing and boating, are allowed on the reservoir with proper permits. The Olivenhain Reservoir serves as a vital water source for the region's residents and supports the local agriculture and recreational industries.

About Olivenhain Reservoir
Where does the data for Olivenhain Reservoir 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.
