Crossbow Herbicide lists on the product label that it is toxic to fish and may be toxic to aquatic invertabrates. Drift and runoff may be hazardous so treatment should be kept at least 15 feet away from the shoreline to prevent getting into the water. A better option would be something actually labeled for use around aquatic sites such as Diquat or Rodeo.
