I primarily fish the Ford and Escanaba Rivers early on. The Ford has been good, but most of the bigger fish are further upstream and hard to reach with a boat. Now's a good time to float the river in a canoe or kayak, from the Hyde bridge, down to the mouth.
I haven't had a chance to fish the Escanaba yet, but I've heard it's been slow so far.
I haven't seen anyone fishing the shallow flat between the Escanaba River and Gladstone, yet. That's a good spawning flat that can hold a lot of fish. Forecast for the next two weeks has highs in the mid to upper 60's, so they should be in any time now.
The regular possession season opens on the 28th if I remember right. Normally Ogantz Bay on Big Bay de Noc is good right from the start of the season. There should be plenty of fish in there now, too.
Just basic bass fishing, here. Tube jigs, Senkos, Super Flukes, spinnerbaits, and shallow running crankbaits will work in all these areas.
Good luck and let us know how you did.
