Below the dam in the river is good, walk out on middle rocks or wade on the right side shore, cast lures in slack pools, bass (smallmouth and largemouth) pike and occasional musky. Shiners/chubs/suckers work also, probably best in May/early June. Opposite shore has pools/slack water also. Panfish on livebait same basic approach.
Above the dam -- lake by the dam or anywhere along the shore in either direction for panfish and gamefish.
