This is the authors' summary from a 35-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in O. H. Ivie Reservoir were surveyed in 2013 using electrofishing and trap netting, and in 2014 using gill netting. Anglers were interviewed from June 2010 to May 2013 during a creel survey. Historical data are presented with the 2013-2014 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

O. H. Ivie Reservoir is a 19,200-acre impoundment, when full, 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 was approximately 43 feet below conservation pool during the 2013-2014 sampling period. In April 2014, reservoir surface area totaled 3,142 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 have been conducted since 2001 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). Annual aquatic vegetation surveys have been conducted to monitor changes in hydrilla coverage. 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.
