Mormon Trail Lake has a good all around fishery with quality size largemouth bass, bluegill, redear sunfish, black crappie, walleye, and channel catfish available. Largemouth bass ranging from 12 to 19-inches are common. There is an abundant year class of black crappie in the lake that are 8 to 10-inches. These fish should provide good fishing in 2017. Channel catfish numbers are high making this lake a favorite amongst catfish anglers. The bigger end of the bluegills are 7 to 8-inches. The Adair County Conservation Board stocks walleyes into Mormon Trail to provide diversity in the fishery. The fishery in Mormon Trail has not always been this good. Back in the early 2000's anglers noticed a decline in the numbers and quality of fish in the lake. A grass carp removal effort was initiated to restore aquatic vegetation and increase reproduction and survival of fish.(2017)
