Final Supplemental Watershed Plan - Environmental Assessment for the Rehabilitation of New Creek Site 14, New Creek-Whites Run Subwatershed of the Potomac River Watershed, Grant County, West Virginia.

摘要

The Recommended Alternative is to rehabilitate New Creek Site 14 so that it meets current design criteria and performance standards. Such rehabilitation measures include construction of a concrete parapet wall on the top of the dam embankment to prevent overtopping during the Probable Maximum Precipitation (PMP) event, installation of a new intake riser, lining the principal spillway pipe, installing an impact basin, installing an embankment surface drainage system, and mitigating the temporary elimination of the lakes fishery.
