Channel catfish: A six-fish limit is in place. Jugs and trotlines are prohibited. Target windswept points and coves, especially south of Highway 12. Dawn and dusk are the best times to fish. A rich forage base of shad and panfish helps Otter's muskies grow, with a large feeding flat on the lake's north side by the dam known as Striper Point a great place to catch them in a hungry mood. This weedy area and similar spots - like the one just across the lake and slightly south of the boat ramp - are great places to probe with bucktails or Dragontail spinnerbaits. Bays with green weeds and laydowns are muskie magnets from now through the fall. But when temperatures cool and weeds start to die back, throwing "wood" is usually a better option.
