Fishing Rules and Regulations
Fishing the St. Louis River Estuary: Regulations and Resources
The St. Louis River Estuary, stretching from Duluth, Minnesota to Superior, Wisconsin, offers excellent fishing opportunities for species like walleye, northern pike, smallmouth bass, crappies, yellow perch, trout, and salmon. Its unique location on the Minnesota–Wisconsin border means anglers need to be aware that fishing regulations vary depending on which state’s waters they are in. A valid Minnesota or Wisconsin fishing license is required, and special border water rules may also apply.
Seasonal and Species Regulations
Fishing rules in the estuary include open seasons, size limits, and daily catch limits for different species. For example, walleye typically have a minimum size and daily bag limit, which may differ slightly depending on the state. Northern pike, bass, panfish, and trout also have specific limits and seasons. Certain areas of the river may have seasonal closures to protect spawning fish, such as from the Fond du Lac Dam downstream during spring walleye spawning, or other protected zones in tributaries and wetlands.
Fish Consumption Advisories
Some fish in the St. Louis River, particularly walleye and northern pike, may contain contaminants like mercury or other legacy pollutants. Anglers should consult the Minnesota and Wisconsin Department of Natural Resources (DNR) fish consumption advisories to determine how much and how often it is safe to eat fish from the river.
Why Checking Regulations Matters
Fishing rules can change annually based on population surveys, habitat conditions, and conservation goals. Regulations may include temporary closures, protected species, gear restrictions, and special harvest limits to ensure sustainable fish populations. By reviewing the most current information, anglers help protect the river’s ecology while enjoying safe and legal fishing.
