According to the MDNR

Cheboygan River – Fish have been caught from the mouth all the way up to the Cheboygan Dam.

Ocqueoc River – Salmon can be found throughout the river system. Try spawn, flies, spoons, body baits or plugs.

Rogers City – A few boats anchored in the bay had limited success when casting Cleo’s and fire-tiger body baits. There should be some silver fish in 40 to 70 feet of water. Pier and shore fishing was slow. Anglers are reminded of the spawning closure on the Swan River.

Alpena – Boating traffic has ceased for the most part. Shore anglers might still find a few walleye near the launch or the marina.

Thunder Bay River – Has been seeing all the action. The bite is slow but the salmon that have been caught are larger than last year measuring 28 to 30 inches. Shore anglers have been taking chinook on rubber eggs, flies, and rattletraps. Blue and silver or black and chrome were good colors. Pink flies have also taken fish. Boat anglers caught fish on Hot-n-Tots. A few pink salmon were also caught.
