Yes, there’s a river gauge in Durand. I’d download an app to monitor it if you’re serious about fishing the river. Use extreme caution out there. In over 20 years of fishing it in my youth there were constant unforeseen dangers. You can be in 18” of water or 12’ in a matter of a few feet in some areas. Take your time, wear a PFD, and use a reliable boat as the current really moves out there.
There are some fairly productive spots just North of Durand. If you’re into catching mid-sized smallies, the lower Chippewa is tough to beat for numbers from now through early Fall.
There is a population of ‘eyes but it takes some pretty good knowledge of the area or a lot of blind luck to stay over the fish.
Other species I’ve caught in my younger years in that area include: drum, crappies, bluegill, carp, longnose gar, muskie, perch, channel cats, flatheads, pike, buffalo, red horse, shovelnose sturgeon, and paddlefish.
