Fishing Outlook: Ripley Lake has a good looking northern pike population (5.1/gill net), with fish averaging 20.0 and the longest being 28.8 inches. 2015 netting showed a naturally reproducing Walleye population and the 2014 year-class was fairly strong. Those age-2 fish averaged 11.1 inches in length mid-July, 2015. A few trophies were also swimming around the lake, with the longest Walleye sampled being 27.2 inches. Ripley also has a quality panfish population. Gill netted black crappie averaged 10.3 inches in length. Good numbers of bluegill were trap netted (9.1/net) and fish over 8 inches in length were present. Source: MN DNR
