In response to the disastrous flood of 1935, the U.S. Army Corps of Engineers, in association with the Harris County Flood Control District, began an extensive program of reservoir construction, removal of stream-bank vegetation, and channelization to reduce Houston's flooding risk. The two most prominent flood control features in the Buffalo Bayou watershed are the Addicks and Barker reservoirs in western Harris County, which provide a combined of open land for runoff storage. In recent years, extensive suburban development upstream of the reservoirs has stressed this flood control infrastructure.
