Houghton County Drain Commission will begin drawing down Otter Lake, allowing for necessary inspections and repairs to Otter Lake Dam. The Otter Lake drawdown will ...more not exceed 6 inches per day, with a total drawdown of 2.5 feet. Boaters are cautioned that the water level drop will make launching difficult at the lake's access sites. Late evening hours are a good time to spear, or to shoot pike with bow and arrow. Try frog, mouse and duckling patterns that make a lot of movement on the lake surface. Both fly and spinning tackle can be used as well.
