The lake here is one of several TVA lakes in the area. The lake level begins to be drawn down in early July through December. If they actually keep it on schedule there can be excellent production of moist soil foods especially yellow-nut sedge at the higher elevations. This years production of YNS tubers was fair to good. Recently rainfall bumped the lake level up flooding the YNS for a week and the ducks responded quickly making the water brown with mud from their digging. Now that the water has dropped back out again one can see the holes dug out which range from small dimples to 1 - 3 foot wide 6" deep holes.
