Reservoir Description

At conservation pool, O.H. Ivie Reservoir is a 19,200-acre impoundment and is located on the Colorado and Concho Rivers in Concho, Runnels, and Coleman counties, Texas, approximately 55 miles east of San Angelo. Water level fluctuations are common; the reservoir surface elevation ranged from 37 to 40 feet below conservation pool during the 2017-2018 sampling period. In May 2018, reservoir surface area totaled 5,034 acres. Habitat features consisted of standing timber, rocks, and flooded saltcedar.

Management History

Important sport fish include Largemouth Bass, White Bass, White Crappie, and catfishes. Annual electrofishing and creel surveys were conducted from 2001 to 2013 to evaluate the effectiveness of the 2001 Largemouth Bass length limit change (from 18-inch minimum length and 5-fish bag to a 5-fish bag, 2 of which may be <18 inches). The 18-inch MLL on Smallmouth Bass was removed in 2015 and replaced with statewide regulations. A variety of fish species have been stocked in the reservoir including Threadfin Shad; Bluegill; Channel, Blue and Flathead Catfishes; Florida Largemouth Bass; Smallmouth Bass; White Crappie; and Walleye. Walleye stockings were discontinued after failing to produce a fishery.
