I saw high 60s to low 70s surface temps on a lake on the northern edge of Chippewa County yesterday.
Some smallies were on beds, some were not...so one largemouth on a bed...but it looked confused. Male smallies on beds were aggressive in protecting their turf.
Lake is 1800 acres, up to 100 ft. deep and clear water.
I was out from noon until just before 8:00 PM, fishing was consistent with a spike in the action right around 6:00 PM.
