About Lake Koshkonong

Tucked into Wisconsin, United States, Lake Koshkonong is a lake that fishes differently season to season. Spring brings fish into the shallows to spawn or feed on early baitfish; midsummer pushes them to cooler, deeper water; autumn turns them aggressive again as they pack on weight before winter. Anglers planning a trip to Lake Koshkonong should check water temperature and recent weather — a sudden cold front can shut a lake like this down for a day.

Fishing Techniques

  • For Walleye

    Focus your efforts around dawn and dusk, as walleye are typically more active during these low-light periods; use a slow, deliberate retrieve, as walleye often prefer a subtle presentation.

  • For Largemouth bass

    Vary your retrieve speed and lure presentation until you find what the bass are keying on, as their preferences can change daily based on weather and water conditions.

  • For Northern pike

    Vary your retrieval speed and add pauses to entice strikes, especially in colder water.
