Sturgeon can live to be over 100 years old and grow to be a whopping 7 feet long and 200 pounds. 

The St. Croix National Scenic riverway supports over 100 species of naturally reproducing fish thanks to great water quality and habitats that supports this incredibly diverse fishery. Paddlers and anglers enjoy the twists and turns of the St. Croix and Namekagon rivers, with varying currents, ever-changing backwaters, natural shoreland and an array of wildlife drawing people from around the globe. Even more “reeling” than feeling a trophy-sized fish tug at your line for some is the experience of spotting the prehistoric-like lake sturgeon, a species that has inhabited our waters for over 100 million years. 

These freshwater giants can live to be over 100 years old and grow to be a whopping 7 feet long and 200 pounds. Despite their impressive size, lake sturgeon have the curious but spectacular habit of leaping entirely out of the water, appearing to stand on their tails, and then landing with a resounding splash. Experts theorize that this may be an attempt to shake off lampreys, parasitic fish that attach to host fish. Most adult sturgeon have one or more old lamprey scars and it is not uncommon to see six or more lampreys attached to one fish.
