The principle impacts to fish result from management that increases surface disturbance, resulting in sedimentation and other adverse impacts to water quality and quantity in fishbearing streams. Increased sediment in fish habitat (streams, rivers, and reservoirs) decreases the potential for fish to naturally reproduce, fills in pools, leads to channel degradation, decreases light penetration and productivity, alters fish community composition, and increases stream temperature. Alternative C places the fewest restrictions on surface-disturbing activities and has the greatest potential to adversely affect fish habitat, followed by alternatives A, D, and B respectively. Alternative D is projected to result in greater surface disturbance than Alternative A, but contains more stringent reclamation requirements that may limit erosion to a greater degree and, therefore, mitigate adverse impacts to fish habitat. Alternative B would result in the greatest direct beneficial impacts to fisheries through proactive management (e.g., watershed improvement projects), followed by alternatives D, A, and C respectively.
