The Trout Angler's Edge
When fishing in early season Wisconsin you need to think stream temperatures. Fast water typically means no trout in cold water.
They need to expend too much energy to hold in place in fast water.
Andy and I had mapped the bottom the year prior in this hole. There were a couple of deep bellies in this hole that trout could lay in and stay out of the fast current.
Lots of folks tell you to stay out of the holes after you fish them. I am quite the opposite. I do recon for the next trips. I do a fast cursory check for future trips.
