Lake Hefner At Oklahoma City reservoir
Lake Hefner At Oklahoma City
Lake Hefner is a man-made reservoir located in Oklahoma City, Oklahoma. The lake was built in 1947 as a public water supply for the city. It covers an area of 2,500 acres and has a maximum depth of 94 feet. The lake is fed by several smaller creeks and streams and its water is used for irrigation, as well as for recreational activities such as boating and fishing.
Lake Hefner receives its water from two main sources: surface flow and snowpack. Surface flow is the water that flows into the lake from surrounding streams and creeks. Snowpack is the accumulation of snow in the surrounding mountains that melts in the spring and summer, contributing to the lake's water levels.
The lake is also used for agricultural purposes, as the water is utilized for irrigation in the surrounding farmland. In addition, the lake is a popular spot for recreational activities such as boating, fishing, and hiking on the surrounding trails.

About Lake Hefner At Oklahoma City
Where does the data for Lake Hefner At Oklahoma City 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.
