Welcome to Ottawa Lake Fen. Wisconsin's 128th State Natural Area.
"Ottawa Lake Fen features lakes connected by a deep marsh and extensive shallow marl flats with a unique assemblage of both alkaline and acid-loving plant species. Ottawa Lake is a remnant lake located in an old glacial lake basin at the edge of end moraine deposits. The smaller northern lake is fed by numerous seepage springs, bubbling springs, and cold inlet streams and flows south into the larger Ottawa Lake. An unusually large number of wetland and aquatic plant communities occur within the site including submergent and emergent aquatics, southern sedge meadow, and shrub carr. The extensive fen-like marl flats are dominated by spike rushes along with pitcher plants and gentians. The natural area is also rich in animal life including clams and snails. Wading birds and waterfowl frequent the shallows. Birds include green heron, blue-winged warbler, yellow warbler, and willow flycatcher. Ottawa Lake Fen is owned by the DNR and was designated a State Natural Area in 1976."

Part of SNA #128 had a little help from volunteers a few years ago. The area had become thickly wooded, which is not what this area was historically. They removed invasive plants and trees like buckthorn, and also fixed and defined the spring-fed stream that now flows freely again to the lake it feeds. The first photo faces east and was taken the summer before the restoration had started. The second photo faces west and wast taken this past autumn. The area will be monitored as native species regrow, and unfortunately, so will some invasives.
