Fishing Forecast

The last fish survey completed at Cocklin's was in 2012. The largmouth bass population looks acceptable for both numbers and size. The catch rate from this fish sample exceeded 100 fish per hour which is above average and contained bass up to 16-inches. The average size of the bass was 11-inches. It is this type of bass population that produces the best bluegill quality. The average length of bluegills in the sample was 7.2-inches and some fish were above 8-inches. The good number of 20-inch channel catfish were sampled in 2010. Cocklin's Fish Farm is heavily used by campers and has great shore fishing oppertunities. The fishery is well suited for this type of use.(2013)
