Red Rock Reservoir provides a diverse and quality fishery. A large fish sampling effort was completed in 2012 with additional gill netting during the fall of 2013. Largemouth bass were sampled in sizes from 9 to 18.5 inches with the largest group being 13 to 16 inches. Bluegill were sampled in sizes from 3 to 7.5 inches with most at sizes not desirable for angler harvest, which is common for large flood control reservoirs. Both black and white crappies are present in excellent numbers and quality size. Both species were similar size in 2013 running from 9 to 13 inches. Good to excellent crappie fishing should continue. White bass are very abundant from 6 to 18 inches and are a popular target for anglers during the summer months. A good group of 11 to 14 inch wipers were caught in 2013. These wipers will grow fast with the abundant shad and should be in the 17 to 20 inch range in 2014. Wipers were sampled over 20 inches. Channel catfish are also highly abundant with great numbers of fish from 17 to 28 inches. A good population of walleyes exist, although anglers usually only note the occasional catch. Walleyes were found in two size ranges in 2013 from 9 to 11 inches and 15.5 to 22 inches.(2013)
