About this spot

Fishing info

  • Experience

    The fishing spot offers a range of freshwater species like walleye, channel catfish, and northern pike. It's notable for having a large walleye population, which is a major attraction for trophy-seeking anglers. The area is equipped with amenities such as boat ramps, piers, and docks, supporting various fishing activities. Additionally, family-friendly facilities and picnic areas contribute to a more enjoyable visit. However, the shallow depth, not exceeding 8 feet, can be a limitation, particularly during warmer periods. The description as a mud flat with weed lines may pose navigation challenges.

  • Tips

    Anglers should adapt their fishing tactics according to seasonal changes. Daytime fishing is advisable due to temperature drops in the evening. Using minnows or worms while jigging around bridges and channels can be effective for catching walleye. Additionally, targeting weed lines and rock piles may improve fishing success. However, in colder months, reduced fish activity could complicate catches. During high precipitation periods, caution is advised when navigating boat ramps or piers, as they may be affected by flooding or muddy conditions.

  • Fishing seasons

    The fishing conditions at this spot vary with the seasons. During the summer months, higher temperatures create favorable conditions for warm-water fish, complemented by moderate wind speeds that enhance the overall fishing experience. In contrast, winter presents challenges with colder temperatures and limited daylight, potentially reducing fish activity. Spring brings high precipitation rates which can affect water clarity and fish behavior, making the fishing conditions more unpredictable.
