Heart Lake in Marinette County: How and When to Fish It

• Overview

  Wisconsin holds Heart Lake, in Marinette County. This is pine and birch ground. The water measures roughly 4 acres, so nothing here is far from anything else. It is one of the smaller waters we list in Marinette County. Nearest place of any size is Niagara, 27 miles away. Beyond it, Kingsford at 28 miles and Iron Mountain at 30 miles. One jurisdiction covers this water end to end.

• Where to Fish on Heart Lake

  Depth is not on record here, so the bank has to tell you. A natural lake fishes on cover, and cover here means weed and timber. The shallow end warms first and pulls fish in ahead of the rest. Species logged across Marinette County include brown trout, rainbow trout, largemouth bass, bluegill and yellow perch. Records at county level tell you what is around, not what is stocked here. The shape of Heart Lake rewards a slow walk along one bank.

• Seasonal Patterns

  The range across the year is 12°F to 67°F. Spring and autumn carry the fishing; summer and winter test it. Count on hard cover from midwinter, and open water from mid April. In an average year the thaw lands around mid April and the freeze near early December. Fish feed hardest at the start and the close of the open season. That is the shape of the year on Heart Lake.

• Tackle & Baits

  Our records carry no access rule either way. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Check whether a boat is allowed before you tow one. Where parking is tight, arriving early solves most problems. Murbou Lake at 0.3 miles is the sensible second choice. Confirm access to Heart Lake locally before you travel.
