Radke Lake Fishing near Princeton, Minnesota

• Overview

  Look for Radke Lake in Isanti County, Minnesota. Country round the bank runs to mixed forest. Surface area runs to about 14 acres — small enough to read in one session. It is a small entry by Isanti County standards. Princeton lies 5.5 miles from the water. Zimmerman is 13 miles away, with Milaca at 13 miles. The county line runs close by, so rules can change within a short drive.

• Where to Fish on Radke Lake

  Open data we checked carries no depth for this water. The shallow end warms first and pulls fish in ahead of the rest. A natural lake fishes on cover, and cover here means weed and timber. County-wide records name largemouth bass, yellow perch, bluegill, common carp and northern pike. The county figures include rivers and lakes alike. Take Radke Lake a stretch at a time.

• Seasonal Patterns

  Typical July readings run about 70°F; by January the average is down near 9°F. A solid cap is the normal state through winter. Ice is part of the season here, ending near early April. The open-water window runs from around early April to about late November in an average year. Just after the ice goes and just before it returns, the fishing lifts. At Radke Lake the season follows that pattern closely.

• Tackle & Baits

  Whether the bank is open is not something our records settle. 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. Where the road in crosses private land, ask first. Where parking is tight, arriving early solves most problems. Failing this one, try Lesure Heath Lake, 0.7 miles away. None of that is settled for Radke Lake in what we hold.
