I talked to one of the worker at the bait shop in Marinette. They said only a few is starting to show up.
Menominee River, Marinette County
MOON PHASE (38%)
Above 80° F
Fished Monday evening till midnight, no other trailers in the lot. We casted cranks and did well. We had 9 nice eyes between 15 and 23, lost a few more. My son did have one large fish hit and make a big run, cut off 30 lb braid, we guessed it was a musky or very big northern.
56° - 60° F
66° - 70° F
Fished the river last night for the 1st time in a few weeks. Casting crank baits I caught a few fish but nothing to take home. Caught a rock bass, a 16" smallie and this guy that was a little short of 28", all still swimming. Only two other trailers in the lot.
