Site Specific Water Quality Criteria for Fish and Aquatic Life in the Canadian Portion of the Flathead River Basin: Nitrate, Nitrite and Ammonia (D.D. MacDonald, L.E. Fidler & D. Valiela, 1987)
This report develops site-specific water quality criteria for nitrogen compounds (nitrate, nitrite, and ammonia) in the Canadian portion of the Flathead River Basin to support fish and aquatic life and address concerns about potential impacts from proposed coal mining and oil/gas development. The criteria account for nitrogen cycling processes, physical and chemical factors affecting toxicity, and the specific life stages and species of fish present in the system.
