Lake Hefner at Oklahoma City

Reservoir Levels Weather Hydrology


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.
