Dethloff Slough Fishing near Cohasset, Minnesota

• Overview

  Dethloff Slough belongs to Itasca County, Minnesota. The bank is 1,316 feet above sea level. It measures about 27 acres, which is a comfortable size for bank fishing. Cohasset sits 5.3 miles from the bank. Grand Rapids lies 7.3 miles off, Coleraine another 8.1 miles. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Dethloff Slough

  There is no recorded depth, so work from what you can see. A natural lake fishes on cover, and cover here means weed and timber. Weed, then depth: that is the order to fish a water of this kind. Itasca County records list yellow perch, largemouth bass, northern pike, bluegill and black crappie among the fish reported. County data is a starting point rather than a guarantee. Anyone new to Dethloff Slough should walk it once before setting up.

• Seasonal Patterns

  On the long-term average, July reads 67°F and January reads 5°F. The season turns properly here, and fish follow it closely. Hard cover is dependable here; it goes around mid April. Averages suggest open water from about mid April through to roughly late November. Just after the ice goes and just before it returns, the fishing lifts. Dethloff Slough runs to that rhythm year in and year out.

• Tackle & Baits

  Nothing in our records says who may fish here. There is no mapped parking or launch close by, which usually means walking in. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Parking is often the real limit rather than the bank itself. Access can change hands, so last year's answer may not hold. Mallard Lake, 2.3 miles away, makes the obvious fallback. The position on Dethloff Slough is worth confirming on the day.
