The Village of Mazomanie’s restoration of the 17-acre former mill pond that has served the area as a family recreational fishery since its construction in 1855 is nearly complete with restocking of fish planned to begin this fall.
The Lake Marion project is one of three local outdoor recreational projects that resulted from the Wisconsin Department of Natural Resource’s 2012 decommissioning of the old dam on lower Black Earth Creek at Mazomanie that diverted water to fill the mill pond. Related projects were the remeandering and restoration of the local part of the nationally renowned trout stream and construction of the Wolf Run Trail along the creek from downtown Mazomanie to Wisconsin Heights High School for year-around multi-recreational use.
In 2014 the Village of Mazomanie constructed a new high-capacity groundwater well adjacent to Lake Marion to replace Black Earth Creek as the lake’s new permanent water supply. Last year village contractors installed a new $650,000 lakebed liner to fix a chronic problem of leakage from the manmade impoundment. Refilling the lake with 50 million gallons of well water to a maximum depth of 10 feet began in November.
The village park at the lake is again open to the public for picnicking, walking the 1.3-mile shoreline, and wildlife viewing. Paddle and sail craft are allowed, from a public launch site at the south end of the lake adjacent to the pump house. Swimming and wading are not permitted.
Replanting of aquatic vegetation is underway in preparation for adding bluegill, crappie, and bass beginning later this year. A handicapped fishing pier is maintained by the Wisconsin River Sportsmen’s Club.
Lake Marion Park is located at 10497 County Highway KP. Pedestrians and bicyclists may also access the park via Lake Marion Trail, another recent Village construction project, that connects downtown Mazomanie with the lake park and CH KP. The paved trail includes a 105-foot long boardwalk/bridge and changes 22 feet in elevation throughout its half-mile length.
