Where the big smallmouth are being caught in the summer - it's even difficult to float a kayak through much of the river's shallow course. It's that shallow up river. We wade and hip waders are that's required. Four feet of water is considered deep with a great deal of it being far shallower, and that four feet or water is rare and it's most often in the form of small holes or cuts in the bedrock, also some washouts along the shoreline, etc. In the winter they drop the lake 25 feet, so some really extreme water level changes that cause the lake to lose something like 60-65% of it's summer water volume.
