I can personally attest to the Crappie fishing at Grand Lake St. Marys. Last weekend I saw at least four 14/15inch Crappie come out of the channels at Kozie Campground around fallen trees and other woody structures. Harmons Landing is also a hot bed for Crappie and most successful fishing has been with minnows suspended by bobbers and small plastics and marabou jigs. Use cut shad for catfish and wax works for the plethora of mixed size bluegills.
