I remember reading about that shortly after it was first discovered and then when the treatment occurred. I have been to that lake as it is not far from where I live.
The only downside to that is if there are hybrid striped bass or striped bass in a body of water they are sensitive to potassium. Something I learned in aquaponics, as some growers add postassium to the water for their plants. Big no no if you have hybrid striped bass.
