Mayhew Lake in Cook County: How and When to Fish It

• Overview

  Set in Cook County, Mayhew Lake is a Minnesota water. The bank is 1,808 feet above sea level. At about 216 acres, a day is enough to walk the shoreline properly. Around 4.4 miles of bank, which is a long day on foot. Few waters listed in Cook County are bigger. Start from Grand Marais, 25 miles down the road. Then Neebing, 54 miles, and Ely, 60 miles. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Mayhew Lake

  Depth is not on record here, so the bank has to tell you. A soft bed grows weed late into autumn, which keeps fish shallow. Still water like this holds fish on the edges rather than out in the open. Survey and observation records for Cook County include white sucker, yellow perch and northern pike. County data is a starting point rather than a guarantee. The near bank of Mayhew Lake is often the one people ignore.

• Seasonal Patterns

  Temperature averages peak at 63°F in July and bottom out at 4°F in January. Four clear seasons, with a proper winter at one end. The lid arrives early and lasts until roughly early May. Average temperatures cross freezing around early May in spring and again near mid November in autumn. Late spring and early autumn carry the year between them. On Mayhew Lake the same rules apply, with local timing.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Records list it as a natural water body rather than an impoundment. Mapping shows parking within half a mile. Mapping shows a jetty some half a mile off. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A phone call first saves an afternoon. Some water is controlled locally without a sign saying so. East Pope Lake, 0.7 miles away, makes the obvious fallback. Treat access at Mayhew Lake as something to verify.
