The Fence River is a tributary of the Michigamme River in Iron County on MichiganâÂÂs Upper Peninsula. It drains forested uplands and wetlands in the south-central portion of the county and flows generally east to join the Michigamme River, part of the Menominee River system that reaches Lake Michigan.
Headwaters arise in interior wetlands and small lakes in Iron County. The river meanders through mixed northern hardwoodâÂÂconifer forest and low glacial terrain, gathering short tributary streams before entering the Michigamme River in the countyâÂÂs eastern drainage.
The basin occupies glacial till and outwash typical of the MenomineeâÂÂMichigamme uplands. Gentle gradients in the upper reaches create oxbows and backwater wetlands; short bedrock or coarse-gravel sections near the lower river produce riffles and small drops.
Uplands support sugar maple, birch, and aspen mixed with hemlock, white pine, and spruceâÂÂfir. Riparian corridors include alder thickets, cedar swales, and sedge meadows. Cool, shaded reaches and spring inputs provide habitat for cold- to cool-water fishes; warmer backwaters near the confluence support species typical of the Michigamme main stem.
