Preston Reach Habitat Complexity Project – Phase 1
Environmental Assessment and FONSI

After considering the environmental impacts of the proposed action, Reclamation has issued a Finding of No Significant Impact (FONSI) for the Preston Reach Habitat Complexity Project Phase 1 Environmental Assessment (EA) completed on July 30, 2010, which documents the environmental effects of six alternatives to improve a section of eroded bank line along the Entiat River, Entiat, Washington.

Alternative D, the preferred alternative, includes the installation of Large Woody Debris (LWD) structures and riparian plantings into the existing eroded streambank, which will increase the habitat complexity to a greater degree than the other four Action alternatives and the No Action alternative outlined in the EA. This alternative will provide the immediate structural stability and complexity needed for the currently eroded bank and offers a greater long-term likelihood of success through the establishment of the planting zones behind the proposed LWD structures.
