Alamo Lake State Park in western Arizona centers on a reservoir created by Alamo Dam on the Bill Williams River for flood control and recreation. Built by the Army Corps of Engineers in 1968, the earthfill dam created a lake whose levels can rise dramatically during seasonal storms, helping make it a notable fishing and recreation destination in the 1970s and 1980s. Stocked with largemouth bass, crappie, catfish, and tilapia, the lake hosts fishing tournaments and at least one Arizona state record. The park’s remote desert setting also supports camping, wildlife watching, bald eagles, and some of Arizona’s darkest skies for stargazing.
