if your fishing a hole go up stream and look in water and wander around in water looking under the rocks just turn the bottom towards you to match the hatch or feed
then come back to the hole and fish ....the whitefish in the hole that may have been dormant are now turn on feeding as when one in the school starts to feed the whole school is now turn on ..
ooopppps ss its like chumming the hole but its natural as you walk around in the river you stirred up the bottom and fed the hole
I have had a hole that I could only get 2 small ones turn on and got 60 in less than 1 hr lots way bigger
