Alton Lake Fishing in Cook County, Minnesota

• Overview

  Alton Lake lies in Cook County, in Minnesota. The ground around here is lake country bush. This is sizeable water at about 969 acres, and a boat opens up most of it. You are looking at roughly 8.6 miles of shoreline, with plenty of water between access points. Few waters listed in Cook County are bigger. Nearest place of any size is Grand Marais, 28 miles away. It is 85 miles to Thunder Bay, the nearest city. This one is safely inside the county line.

• Where to Fish on Alton Lake

  Charted depth runs to roughly 82 feet at its lowest. Where the bottom changes texture, fish gather; find that line. Still water like this holds fish on the edges rather than out in the open. County-wide records name white sucker, yellow perch, northern pike, rainbow trout and walleye. The county list is broader than any single water. Work Alton Lake in sections rather than trying to cover it.

• Seasonal Patterns

  Temperature averages peak at 63°F in July and bottom out at 5°F in January. The middle months are generous; the ends are demanding. Count the season from break-up, usually late April. Averages place the thaw at late April and the freeze at mid November. Reckon on open water from spring through to late autumn, with May and June the strongest. That is the shape of the year on Alton Lake.

• Tackle & Baits

  No access rule appears in what we hold. No dam controls it, and the level follows the season. There is camping recorded roughly half a mile off. Mapping records toilets within half a mile. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Read any posted signs at the access point rather than assuming. Some water is controlled locally without a sign saying so. Ella Lake, 1.8 miles away, makes the obvious fallback. Confirm before you fish Alton Lake.
