Reservoir Description

Averhoff Reservoir (174 acres) is a riverine reservoir located on the Nueces River, near Crystal City, TX, in Zavala County. It was constructed by the Zavala-Dimmit Water Improvement District Number 1 in 1948 to provide water for agricultural, recreational, and flood control purposes. Water level records are currently not recorded. Access was fair with only one public ramp and there were no handicap specific facilities. The primary shoreline habitat feature was overhanging brush. Aquatic vegetation occupied about 4 acres of the reservoir with Illinois pondweed, Egyptian paspalidium, and stargrass being the predominant species.
