Providing Municipal and Industrial Water Supply
to the Cities of Del City, Midwest City, and Norman, Oklahoma.

Welcome to Central Oklahoma Master Conservancy District


Lake Thunderbird, also known as the Norman Project, is a federal Bureau of Reclamation (BOR) project, that is located at the confluence of Hog Creek and Little River in Cleveland County, Oklahoma about 13 miles east of Norman and about 30 miles southeast of Oklahoma City.

The purpose of the project is to provide storage for Municipal and Industrial (M&I) water, flood protection to lands south and east of the project area, and significant recreation and fish/wildlife benefits. The dam was completed in 1965 and provides water supply to the cities of Norman, Midwest City and Del City and supports the recreational activities associated with Lake Thunderbird State Park.

The Central Oklahoma Master Conservancy District (COMCD) was established in 1959 and manages, through a contract with the BOR, the operation and maintenance of the water supply facilities. It also works with the US Army Corps of Engineers to regulate flood waters and helps support the recreational benefits managed by the Oklahoma Department of Tourism and Recreation. The District is governed by a seven-member Board with three representatives from Norman and Midwest City each, and one representative from Del City.
