OMAHA, Neb. – A draft environmental assessment for a proposed rehabilitation project at four Salt Creek Dam sites is available for public review. The draft EA evaluates the environmental impacts of installing filters to address potential seepage issues at the following dam sites: Olive Creek Dam Site 2 (located approximately four miles southwest of Sprague), Wagon Train Dam Site 8 (approximately two miles east of Hickman), Stagecoach Dam Site 9 (one mile south of Hickman) and Pawnee Dam Site 14 (approximately four miles northwest of Lincoln).

The proposed construction activities outlined in the draft EA include excavating earthen material around the conduit on the downstream slope of each dam and installing a filter of granular material along the conduit to allow for the filtered exit of any potential seepage. Risk reduction measures will be incorporated into the design to eliminate blowout concerns during excavation. These proposed modifications are structural only and will not change the operation of the dam for water control or flood risk management.

This EA also assesses the impacts of Nebraska Game and Parks Commission boat ramp improvements and a fishery renovation project at Stagecoach Dam. The boat ramp improvements include installation of a breakwater, removing the existing ramp and placing a realigned ramp and canoe launch with ADA features, and adding gravel to the dam and spillway road surface to improve access. The fishery renovation would include lowering the reservoir 10.1 feet that would occur after September 4, 2017 to minimize impacts to recreation at the lake. The purpose of this proposed project is to improve boating access and fishing quality at Stagecoach State Recreational Area.

This draft EA is consistent with the National Environmental Policy Act of 1969, as amended, the Council on Environmental Quality’s regulations for implementing NEPA (40 CFR 1500-1508), the Corps’ regulations for implementing NEPA (33 CFR 325 and Engineering Regulation 200-2-2) and other applicable environmental laws and regulations.
