Introduction to the Rainy River on Lake of the Woods

Nestled in the heart of northern Minnesota lies the Rainy River, a haven for anglers seeking the thrill of catching the legendary lake sturgeon. Connecting to the vast expanse of Lake of the Woods, this pristine waterway offers an unparalleled sturgeon fishing experience, particularly during the spring months. 

This large US–Canada border waterway stretches approximately 137 miles from Lake of the Woods to the vast network of lakes near International Falls. On the river’s south side sits Minnesota while Ontario is on the North.

Understanding Sturgeon: The Majestic Giants of the Rainy River

Sturgeon, often referred to as the “dinosaurs of the deep,” are an ancient fish species that have inhabited the waters of the Rainy River for centuries. With their distinctive elongated, torpedo-like bodies, bony external plates, flattened snouts and a mouth that can be extended from beneath their head, these majestic giants can grow to impressive sizes, making them a prized catch among anglers.

They rely on extensive shallow waters to hunt for food, using their barbels to lightly probe the bottom in search of prey. Their diet consists of insect larvae, various invertebrates, snails, leeches, small mussels, and tiny fish. 

Sturgeon are larger than the more common large fish such as northern pike and muskies. Minnesota lake sturgeon stand out among other large freshwater fish both due to their unique characteristics and ecological significance. Unlike many other freshwater species, sturgeon possess a prehistoric allure, with their long bodies and bony plates (called scutes), and distinctive whisker-like barbels near their mouths. 

What sets Minnesota sturgeon apart is their remarkable resilience and longevity; these ancient fish can live for decades and grow to impressive sizes, with some individuals exceeding six feet in length and weighing hundreds of pounds. 

Moreover, sturgeon play a crucial role in freshwater ecosystems as indicators of environmental health and contributors to nutrient cycling. Their migratory behaviors, spawning rituals, and ability to thrive in diverse habitats make Minnesota-based sturgeon both fascinating subjects for anglers and vital components of the state’s aquatic biodiversity. Their importance is why they are monitored and protected.

Migratory Patterns: When and Where to Find Sturgeon

It’s said that the best place to catch sturgeon in Minnesota is called the Four Mile Bay of the Rainy River where it meets Lake of the Woods.

The migratory patterns of lake sturgeon on the Rainy River are a fascinating phenomenon deeply intertwined with seasonal changes and reproductive behaviors of these interesting creatures. Here’s a comprehensive description of their migratory patterns:

Spring Migration:

As winter loosens its grip and temperatures begin to rise, lake sturgeon embark on their spring migration in the Rainy River. Typically starting in late March or early April, as the ice thaws and water temperatures increase, sturgeon that have spent the winter in deeper pools and holes begin to move upstream.

During this time, sturgeon gather near the mouth of the Rainy River, where it meets Lake of the Woods. Here, the fish congregate in preparation for their journey upstream. The warming waters trigger a surge of energy in the sturgeon, prompting them to seek out spawning grounds in the upper reaches of the river. 

This is why the River Bend Resort near Baudette is such a great fishing spot for sturgeon in the spring. Our location is right on the sturgeon highway! And we know all the hotspots in their path.

Summer Habitat:

As spring transitions into summer, lake sturgeon settle into their preferred habitats along the Rainy River. Because sturgeon are bottom feeders, scavenging for insects, crustaceans, mollusks, and small fish along the riverbed, they seek out areas with moderate to swift currents, rocky substrate, and ample food sources.

Prime locations for sturgeon during the summer months include deep pools, channels, and eddies where they can find refuge from strong currents and predators. These habitats provide the necessary conditions for sturgeon to thrive and grow throughout the summer season.

Fall Feeding and Migration:

As summer wanes and temperatures begin to cool, lake sturgeon shift their focus to feeding in preparation for the upcoming winter months. During the fall, sturgeon become more active in their pursuit of food, scouring the river bottom for sustenance to build up energy reserves.

In late fall, as water temperatures drop and daylight hours shorten, sturgeon start their migration downstream toward deeper, overwintering areas in Lake of the Woods. They seek out deep holes, channels, and backwaters where they can find refuge from freezing temperatures and ice cover.

Winter Dormancy:

During the winter months, lake sturgeon enter a period of dormancy in the deeper waters of Lake of the Woods. They become less active and conserve energy to endure the cold conditions. Sturgeon rely on their remarkable ability to withstand harsh environments, including low oxygen levels and limited food sources, during this time of year.

Throughout the winter, sturgeon remain relatively stationary in their overwintering habitats, waiting for the return of spring when the cycle of migration and spawning begins anew.

In summary, the migratory patterns of lake sturgeon on the Rainy River are intricately linked to the changing seasons and environmental cues. From their spring migration to their summer habitat, fall feeding, and winter dormancy, sturgeon navigate the waters with purpose, driven by instinct and the rhythms of nature. Understanding these patterns is key to conserving and protecting this iconic species for future generations to enjoy.

Springtime on the Rainy River: A Sturgeon Fishing Paradise

Springtime marks the peak season for sturgeon fishing on the Rainy River near Baudette. As the ice melts and the waterways open up, anglers flock to this northern Minnesota boundary paradise to test their skills against these formidable creatures. 

Spawning usually takes place between April and early June. The months of April and May are particularly rewarding, with sturgeon congregating in the shallower waters of the river, making them more accessible to anglers. Conveniently, our sturgeon fishing resort is located right in the area where all of this happens. 

In the springtime, there are variables with ice flow and where you can dock. Our resort is in a good position, with a great place to stay and a full bar & grill.

Sturgeon Keep Seasons, Catch & Release, and Sturgeon Limits in Minnesota

There are two “Keep Seasons” or “Harvest Seasons” for sturgeon in Minnesota:

  • The Spring Keep Season begins on April 24th and ends May 7th. 
  • The Summer Keep Season begins on July 1st and ends September 30th.

Sturgeon are protected, but still can be fished with the “catch and release method” outside of these keep seasons, with one exception. The season is closed to any form of targeting sturgeon from May 16th to June 30th. 

What is the MN sturgeon limit? There is a protective slot on sturgeon allowing anglers to keep one sturgeon per calendar year with tag, between 45-50 inches inclusive (that means any fish caught under 45” or over 50” must be immediately returned to the water), or over 75 inches in length.

Lake of the Woods and Rainy River anglers often enjoy “The Sturgeon Surprise.” While some anglers target sturgeon during the appropriate seasons, many are caught inadvertently year-round while fishing for walleye.

Other Fish in Rainy River in the Spring

Walleye: The Rainy River and Lake of the Woods are a top spot for Walleye. In fact, the region is often referred to as “The Walleye Capital”. But there are a few rules and regulations for boundary border water walleye fishermen need to be aware of. You can no longer target boundary water walleye from April 15th (same date every year) to the second Saturday in May.  That’s when the walleye season opens back up.

Pike: Late season pike spawn in frozen tributaries leading into the bays and shallow breaklines of Lake of the Woods. The Rainy River is a great place to fish northern pike. 

Other Fish: The Rainy River also hosts all the common fish of lakes and rivers in the northern Minnesota and boundary water region such as muskie, smallmouth bass, sauger, crappies, yellow perch, and other smaller forage species.

Best Practices for Sturgeon Fishing

When it comes to sturgeon fishing on the Rainy River, patience and perseverance are key. Since they’re bottom feeders, it’s a game of placing yourself in the correct position and waiting for them to find your bait. 

These fish are enormous, so utilizing sturdy fishing gear and opting for bait such as nightcrawlers or shad can increase your chances of success. 

Additionally, there’s some personal responsibility involved. Practicing catch and release ensures the sustainability of sturgeon populations for future generations to enjoy, so we’ve laid out a few considerations for responsible sturgeon fishing:

  • Before bringing a large fish onto your boat, ensure that fishing rods, tackle boxes, and other loose items are secured out of the way. If someone is reeling one in, a good boatmate will tidy up the area. 
  • Consider using a measuring device attached to the outside of your boat to measure the fish quickly before releasing it, thus avoiding the need to take it out of the water. Some large fish may be too risky to bring aboard a boat; release these big boys without lifting them onto the boat whenever possible.
  • Avoid keeping fish out of the water for too long. It’s easy to get excited when hooking a trophy, but please be conscious of how long the fish is above water to help preserve its life. 
  • It’s not uncommon to fight the fist for longer than 10 minutes. We recommend heavier fishing lines to pull the fish in more swiftly, thus reducing the fish’s stress and exhaustion.
  • When photographing a sturgeon, always support it horizontally; refrain from holding it vertically by the head, gills, or tail, even for photos. Get help from your boatmates. 
  • Never touch a sturgeon’s eyes or gills.
