It was constructed by the Zavala-Dimmit Water Improvement District Number 1 in 1948 to provide water for agriculture, recreation, and flood control. The reservoir was formed by the construction of two dams across two channels of the Nueces River. The dam and lake are managed by the Zavala-Dimmit County Water Impound District. Averhoff Reservoir also serves as a venue for recreation, including fishing and boating.

The surface area is 174 acres with a maximum depth of 28 feet. It has a normal water level of 600 ft. msl with severe fluctuations of 15 feet or more. It has a normal water clarity being clear to slightly stained.

In 2005 Illinois pondweed, which occurred mainly in the lower point of the reservoir, was the primary aquatic vegetation taking up approximately 4 acres.
