Dont bet that water temp is the deciding factor for the spawn . The past 2 trips we have caught males that have been milting and females that spewed eggs when brought through the hole . The water temp down on the bottom in 28ft of water was 38 degrees on Sunday.

like you said no calender , but no thermometer either . As you can tell where the fish have been caught in the past 10 days, they are in the spawning areas just waiting for the mood to be right .

Not saying at all, that all of them were ready but some for sure were .
