According to the Rodeo product label the product can be used in a pond to control cattails and there are no water restrictions concerning fish or water usage. If a large area of the pond needs to be treated you should only treat a 1/3 - 1/2 of the lake at a time to avoid removing too much oxygen from the water which could impact aquatic life in the pond.
