Local attorney Christine Bremer Muggli, 61, of Rib Mountain has lived on the edge of the park since 2002. "So the DNR, in that permitting process, is going to have to make a decision with regard to the trade-offs present." "What happens is, when you dredge, you destabilize those (metals)," Karger said. The Wisconsin Department of Natural Resources will have to approve the dredging, and Karger said that's not a guarantee because of the presence of heavy metals in the sediment, a leftover from the area's industrial past. Water depths in the pond range from 0.5 to 3.8 feet, the study said. "So we need more groundwater, less Wisconsin River water." The purpose of dredging, Karger said, is to get more groundwater into the pond. The pond and its fishery have deteriorated over the ensuing decades, according to the study, with excessive growth of duckweed and other floating vegetation in the summer, thick growths of rooted aquatic plants, and heavy metals in the sediment. The shallow pond, known locally as the "lagoon," was created in 1968 by connecting the mainland to two islands in Lake Wausau with a narrow berm. Karger said half the cost of the project could be paid for by a grant from the Environmental Impact Fund, which provides funding assistance for projects in Marathon County geared toward environmental remediation and/or natural resources protection. Marathon County Administrator Brad Karger, also the project chairman for the local Rotary, told club members Monday at the group's 100th anniversary event that a recently-completed study by Montgomery Associates shows clean-up efforts will run about $180,000, which would include the cost of dredging the pond and planting vegetation around the body of water. Returning the pond to a more pristine state is a project being taken on by Marathon County, The Rotary Club of Wausau and the B.A. The six-acre Bluegill Bay Pond, a popular spot to catch panfish, has become increasingly choked with excessive aquatic vegetation and algae over the years, especially by mid-summer when it often turns into a thick green soup. RIB MOUNTAIN - The restoration of a popular fishing pond in Bluegill Bay County Park in Rib Mountain is expected to cost around $180,000.
