When I was researching for applying it, I was told:

Treatment is based on acre ft. 1 oz of Prinfish (5% rotenone) for every 3818 gallons results in 2ppm. Rotenone will be absorbed by suspended clay - silt particles reducing its effectiveness. Plankton and vegetation can also absorb rotenone minimizing it.

I was inquiring specifically about killing a pond with GSF in it.

Here in Indiana, you need a pesticide applicatior license to buy it, and an aquatic rider on your license to apply it. Any aquatic management company should be able to apply it for you. Look in the resources guide on the home page for one near you.
