Try looking for mud plumes coming from the tributaries, that water will always be warmer than the surrounding water. Troll from the muddy water to the clear water and back again. If the muddy water runs up to the shoreline, fish there. No matter how shallow the water, get your boards right tight to shore, your biggest fish will be hanging there. I once saw a guy in Rochester pull an 18lb Brown from 6ft. of water while his board bounced off the exposed shoreline.
Presentation requires a host of variables that are quite easy to understand.
First off, planer boards are a must, no boards fishing will be slow. Browns are typically boat shy and will swim away from the boat to the waiting lures run from the boards. I've caught Browns from riggers but my success was limited. Run your lures back at least 150ft from the boards and riggers. Next, use light line, 6-8lb. test.
