This is the authors' summary from a 30-page report. For a copy of the complete report, use the download link in the sidebar.

Medina Reservoir was surveyed from June 2004 to May 2005 using electrofishing, trap nets, gill nets, creel, a littoral zone habitat survey, an aquatic vegetation survey, and an angler access and facilities survey. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Medina Reservoir (5,410 acres) was constructed in 1913 and is located on the Medina River in Medina County, Texas. It was built primarily for irrigation water supply. The water level increased about 25 feet in 2000 to near conservation pool elevation and remained within 5 feet of that level until May 2005. Angler access is adequate with one public boat ramp and four private ramps open to the public. Bank angling access is fair and available adjacent to the boat ramps. The reservoir is deep, having an average depth of 46 feet, and relatively infertile with a secchi depth that exceeds 6 feet. Most of the shoreline (75%) is characterized as rock bluff or rocks and gravel. Boat docks occur along 24% of the shoreline. The reservoir contains very little aquatic vegetation with native emergent species occurring along only 1.5 miles of the shoreline.

Management Strategies

All species should continue to be managed under current harvest regulations. Biennial electrofishing, gill-netting, and trap-netting will be conducted to monitor primary sport and prey species and evaluate the success of palmetto bass and largemouth bass stockings. Every fourth year age-0 largemouth bass will be collected and analyzed to assess the genetic composition of the population. To increase public awareness of angling opportunities, a press release regarding palmetto bass stockings will be prepared and signs depicting fish harvest regulations will be posted at boat ramps.
