Although the Authority's own lakes do not contain flood storage space, they are operated so as not to aggravate flooding. Through its partnership with the Corps of Engineers, the Authority has cooperated in the development of the Corps' basin-wide flood control system of reservoirs. In 1941 the Authority completed its first major reservoir project at Possum Kingdom. Morris Sheppard Dam, located on the Brazos River northwest of Fort Worth, has two 12-megawatt hydropower generators. The Authority leases more than 1,500 cottage and commercial sites around the lake.
Possum Kingdom receives an estimated three million recreation visitors annually.
Major activities on the lake include fishing, water skiing and scuba diving. The lake has a public fishing pier, five public boat ramps, public access areas for picnicking, and a total of 400 primitive camp sites. A complimentary map of Possum Kingdom is available at the project supervisor's office or from the Authority's public information office. The Authority completed its second major reservoir, Lake Granbury, in 1969. DeCordova Bend Dam is located on the Brazos River southwest of Fort Worth.
