The upper reaches, from Northland down to Big Falls, are trout water.
Some stretches are rocky, while others have numerous downed trees preventing easy travel.
The rocky lower stretches are prime smallmouth bass territory, but you will also find a mixed bag of other piscatorial prey. I have caught smallys, channel catfish, northern pike, walleye, white bass, sunfish, goldeneye, and sheephead in this river. I have also seen redhorse suckers and at least one musky in this stream. The best section for sustained rock dodging is from the county put-in off of Wolf River Road down to the county park where county highway J crosses the river. From J down to Big Falls, there are a couple of small drops and then the scenic Dells of the Little Wolf.
