The Grand arm has been unusually heavily colored most of the summer and into the fall. It extends down lake throughout the entire arm and into areas below Bucksaw and to the Long Shoal area, parts of which are usually more clear. It doesn't settle or clear during periods when there isn't any runoff or stream inflow. After the heavy rains last week the water color coming in the upper end of the arm is cleaner than the water it's displacing. There seems to be high levels of an algae type coating on trees and rocks. Also see what i think are large, abnormally large, amounts of plankton on the graph, massive amounts which i first thought were shad but it's not. I'd be interested in any scientific opinion or knowledge. Thanks in advance.
