Fishing Forecast

Red Rock Reservoir provides a diverse and quality fishery. A large fish sampling effort was completed in 2012. 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. Black crappie run a little smaller than the white crappie with the average size being 8 inches and individuals up to 12.5 inches. The white crappies are abundant from 8 to 10.5 inches and range up to 14.5 inches. Good to excellent crappie fishing should continue. White bass are very abundant from 8 to 17 inches and are a popular target for anglers during the summer months. Channel catfish are also highly abundant with great numbers of fish from 17 to 28 inches. Hybrid striped bass(wipers) are also present, but were not susceptible to the sampling gear used in 2012. The opportunity to catch a trophy wiper exceeding 20 inches exists.(2012)
