Abstract : This EA addresses two projects proposed for construction on an island downstream of the Red Rock dam. These include the riprapping of its eastern or main channel shoreline and trail development around its perimeter. Placement of riprap would provide erosion protection to the island. Development of a trail would enhance this land use by providing access for activities such as nature viewing, hiking, and fishing. The proposed projects would riprap 1,600 feet of shoreline and provide for 4,000 feet of trails. While would be an immediate loss of vegetation during construction, it is concluded that there would be a long-term gain through the prevention of gradual erosion. The trail would concentrate foot traffic onto hardened paths and provide additional recreational opportunities on public land at Lake Red Rock. No significant impacts are anticipated to result from the proposed projects.
