oxygen concentrations, and pH levels will be affected for the interim of dam removal (U.S. Dept. of the Interior, Apr. 1996, n. pag.). Turbidity, in turn, will be the chief cause of groundwater contamination by infiltration into underlying foundations or well and septic systems (removal (U.S. Dept. of the Interior, Apr. 1996, n. pag.). The implementation of either the Proposed Action or Dredge and Slurry alternatives will also impact the native anadromous (indigenious?) and resident populations on the Elwha River. The high sediment regimes, especially those of the River Erosion Alternative (the proposed action), will encumber the migrating fish over the deconstruction process. However in the long term, runs will improve with the staged delayed of dam destruction, fisheries management (including the supplementation fish stocks through hatchery intervention), unrestricted passage up the full stretch of the Elwha River, and the formation of quality spawning grounds and rearing habitats from the released sediments (U.S. Dept. of the Interior, Aug. 1996, n. pag.). (steph, this last paragraph seems akward) Moreover, apart from the obvious economic profits of salmon run restoration, the heightened decomposition of dead fish after spawning will significantly enrich nutrients cycling through the riparian area (Munn et al. n. pag.). Magnified numbers of anadromous fish will, too, eventually increase the biotic diversity down the length of the Elwha Basin. In the future wildlife will be drawn to the decaying remains of dead fish and their young even though the immediate disturbances during the removal period may ward off certain animals (U.S. Dept. of the Interior, Apr. 1996, n. pag.). Vegetation and marine organisms will benefit from the circulation of organic remains; those primarily adapted to sandy substrates will flourish after the initial strain of post-dam sediment conditions (Winter, 2000, n. pag.; U.S. Dept. of the Interior, Aug....
