N2 - Acid-neutralizing capacity, pH, dissolved organic carbon, Fe 2+, and Mn2+ values were elevated and SO4 2-, Aln-, and dissolved oxygen concentrations were decreased following water transport through the beaver impoundment. The immediate downstream site exhibited significantly lower invertebrate richness and diversity and collector-filterer, Plecoptera, and Trichoptera densities, but significantly higher total invertebrate, Diptera, Ephemeroptera, predator, and collector-gatherer densities. Significant differences were noted primarily during April and July. -from Authors
