Just to resolve the comments about use of herbicides in the water. Milfoil is a real problem in the south and mechanical harvest and chemical treatment is common. A product called REWARD is often used. A Diquat herbicide, it works well on milfoil and is benign in comparision to others. Application rates for milfoil is 2 gallons per surface acre at a cost of about $40.00 per gallon. So for a 1000 acre lake the cost would be about $80,000.
The restricted use of treated water is: drinking water: 3 days
fishing and swimming: 0 days
cattle/livestock water consumption: 1 day
But, the best cure is to make sure the milfoil does not get established and it is our responsibility to stop the spread. We now have a small honda water pump on board so a wash down can be done before we leave a launch site. You'd be surprised how many times other boats leaving, have asked for a wash down........... at a fee of course
