Lake hasn't been sprayed for more than 7 years. Not even the shoreline's. Lack of weeds is due to the over population of carp and shad. They dirty up the water so there is no sunlight getting to the weeds. Amey pond is clear so that's where the weeds are. Lake has been clearer than normal (least clearer than has been recent years. More carp/shad will be taken out this summer. Only 1/4 of what was taken out last spring was taken out this spring. Guess the contract the netters had was lot lower.
My guess it's caused by manure from the creek.
