Had the same thing yesterday…big cat that felt like a monster walleye for a sec.
Bite was finicky for me yesterday. It was non existent in the morning on about 10 spots that are usually pretty productive. The smallies and sheepies were certainly aggressive though.
Finally found about a dozen on a rarely fished spot. Water is still 60 degrees. Cranks and live bait worked. Seems like if you start with cranks on a spot you’ll get a couple active fish. Switch over to bait and pick the more neutral fish off.
Big cool down later this week might charge them up. Would like to see the water get in the low 50’s soon.
