Theodore Roosevelt Dam, the first major structure constructed by the Bureau of Reclamation on the Salt River Project (SRP), spans the Salt River to form a huge reservoir. The dam is 280 feet high and 723 feet long. Once the largest man-made lake in the world, Roosevelt Lake is still the biggest of the six SRP lakes and offers the most recreation opportunities. When full, the lake covers more than 17,000 acres near the confluence of Tonto Creek and the Salt River. Game fish in Roosevelt include largemouth and smallmouth bass, bluegill, channel catfish and crappie. The Lake contains a wildlife area and as a wildlife refuge, is posted to permit hunting at certain times of the year.
