Little Iron Lake Fishing Regulations
Little Iron Lake follows Minnesota statewide fishing regulations — no lake-specific special rules in DNR records.
Little Iron Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake bottoms out at 18 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Little Iron Lake covers 115 acres alongside 7.5 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Cook County's 137 graded lakes, Little Iron Lake ranks 79 — below the local median, though not at the bottom.
