Project Name in Appropriations Bill: Mason Mine 280 at Wills Creek Lake, OH

Authorization: Water Resources Development Act of 1986 (P.L. 99-662), Section 1135, as amended.

Project Sponsor: Ohio Department of Natural Resources (ODNR); Mineral Resources Management Division

Project Stakeholders: ODNR; Office of Surface Mining; Muskingum Watershed Conservancy District ((MWCD); US Fish and Wildlife Service (USFWS); recreational users of Wills Creek Lake

Project Location: The project is located along the south shoreline approximately 4 miles above the Wills Creek Dam. Wills Creek Lake is located in Coshocton, Guernsey and Muskingum Counties, Ohio, and is approximately 55 miles east of Columbus.

Project Background: Large amounts of acid mine drainage (AMD) from the Mason Mine 280 complex are entering Wills Creek Lake and impacting the water quality and ecosystem habitat.

Project Description: The proposed restoration project is intended to treat the discharge of acid mine drainage before it enters the lake. Ecosystem restoration features may include the construction of a system of state-accepted anoxic limestone drains followed by wetland ponds or cells. This system could be employed separately, or in combination, with measures directed to the mine discharge such as hydraulic seals. Results of the study would restore the aquatic habitat in the area where the discharge currently enters Wills Creek Lake.

Project Status: A Preliminary Restoration Plan (PRP) was approved in 1999. The existing PRP was updated to reflect current designs and costs and approved in November 2002. The District has initiated the feasibility study phase and is working to complete it by September 2007.

Fiscal Year 2008 Activities (Oct 07 - Sep 08) subject to availability of funds:

  • Execute a design agreement with a non-Federal sponsor. (ODNR)
