Just to add alittle to this. Check for holes above the bank also. The muskrats need air like us and them mink on my line anyway 9 times out of ten will be caught going down the hole from the top. If there are not holes in sight because of being in deep water, make pocket sets around the pond. A piece of apple in one and fish in the other, that will clean them up along with the coon and mink. Have fun. Justafarmer
