The federal government would then have the right to exert more control over our fish habitat, our water quality, our instream flows, our stream banks, our irrigation systems, our fishing regulations. The delays also affect many types of USFS work, including burning, tree thinning, roadwork, grazing, watershed restoration, and weed control. The bottom line is this. . A. Antimycin and rotenone are fish toxicants registered by the Environmental Protection Agency. Antimycin is a derivative of the human antibiotic streptomycin.
Rotenone is derived from the roots of certain tropical plants.
The active ingredients of Noxfish degrade to concentrations that won't affect fish within 48 hours. Cherry Lake would be treated with antimycin and probably with rotenone. Over the life of the four-year project, we anticipate using fewer than 20 gallons of antimycin and fewer than 10 gallons of rotenone to conduct two treatments of the waters in the entire project area. According to the Montana Department of Environmental Quality's Water Protection Bureau , none of the compounds as they will be used during the project present a human health risk. The lower portion of Cherry Creek will not be affected because the antimycin is expected to degrade in a matter of hours within the project area upstream, and the water in the creek should be nearly detoxified as it reaches the 25-foot waterfall at the downstream end of the project area.
