Abstract: This Environmental Assessment evaluates the environmental effects of the proposed shoreline stabilization project at the Riley Creek Recreation Area on the Pend Oreille River upstream of Albeni Falls Dam, near Priest River, Idaho. Erosion from wave action has caused incremental bank failure along the north shore of the Pend Oreille River, threatening infrastructure and sensitive cultural resources. The primary focus of the project is the construction of rock riprap bank stabilization along approximately 1,980 lineal feet of the shoreline. When complete, the structure will provide protection against erosion from elevation 2,053 feet to an elevation between 2,064 and 2,065 feet, or 1.50 to 2.50 feet above the regulated summer pool level. The project will take place within the U.S. Army Corps of Engineers (Corps)-owned Riley Creek Recreation Area. Impacts from the project are expected to include minor construction related effects on water quality, wildlife, noise, and recreation. These impacts to water quality, wildlife, noise, and recreation will generally be highly localized and of short duration. In addition, approximately 1.6 acres of lakebed will be covered by riprap. The Corps will use best management practices to minimize potential adverse effects to aquatic and terrestrial resources. Impact reduction measures will take the form of plantings of native vegetation, scheduling in the winter low-water months to limit in-water construction, long-term protection of cultural resources, recreation facilities, and on-shore habitats. The proposed project will not constitute a major federal action significantly affecting the quality of the human environment.
