About the Flood
Control District

The Flood Control District is a special purpose district created by the Texas Legislature in 1937 and governed by Harris County Commissioners Court. It was created in response to devastating floods that struck the region in 1929 and 1935. The Flood Control District's jurisdictional boundaries are set to coincide with Harris County, a community of more than 4.7 million people (2020 census) that includes the City of Houston. The other boundaries in which we operate – those provided by nature – are the 23 primary watersheds within Harris County's 1,777 square miles. Each watershed has its own independent flooding problems. Each watershed presents unique challenges. Click on map to enlarge
