Simulated water-level changes resulting from proposed changes in ground-water pumping in the Houston area, Texas

The need for additional water supplies in the Houston area prompted construction of Lake Livingston on the Trinity River in Polk and San Jacinto Counties, about 60 miles (96 km) northeast of Houston, as a source of surface water for municipal supply, industrial use, and irrigation.  Water from the Lake Livingston will become available to users in the Houston area early in 1976.
