O. C. Fisher Reservoir was sampled in 2005 using gill nets. Electrofishing and trap netting were not conducted because of extremely low water levels in fall 2004. This report summarizes the results of the survey and contains a management plan for the reservoir based on those findings.
O. C. Fisher Reservoir is a 5,440-acre reservoir at conservation pool on the west side of San Angelo. The reservoir covered approximately 750 acres at the time of sampling. Habitat consisted primarily of flooded terrestrial vegetation, rock, gravel, and nondescript shoreline. Since 1995, O. C. Fisher Reservoir water levels dropped dramatically to a low of 53 ft below conservation pool in August 2004. The low water levels prevented sampling from 2002 through fall 2004. A major fish kill occurred in September 2004 due to low dissolved oxygen. In November 2004 the reservoir caught over 11 ft of water, making it again possible to sample the reservoir.
- Blue catfish: No blue catfish were collected in 5 net-nights (NN) of sampling.
- Channel catfish: Seven individuals were collected in 5 NN of sampling. These catfish likely came from the January 2005 stocking, when 20,018 advanced (≥9”) fingerling channel catfish were released by TPWD into O. C. Fisher.
- Flathead catfish: One 27-inch individual was collected in 5 NN of sampling.
- White bass: No white bass were collected in 5 NN of sampling.
Continue to respond to the 2004 fish kill and subsequent water rise by stocking bluegill and blue catfish fingerlings at 100/acre, in addition to the gizzard shad, bluegill, channel catfish, largemouth bass, and white crappie that were stocked in spring 2005. Also, a new habitat survey will be conducted in late summer or early fall of 2008, the next standard report year.
