Not so much related to millfoil, but is causing me sleepless nites is a recurring bladderwart problem. I've tried Reward and get some relief, but it never terminates the growth. The lake is 25 plus feet deep and spring fed. Probably has as much flow through as .5MGD Lake size is 57 acres. I've thought about grass carp, but am concerned the carp will consume desired plant growth on the bottom as well. Any thoughts? D
