2 questions.

1) What's the shallowest water you've caught fish in, in February

For me, I've caught them in some back waters in about 8-10 FOW and the fish were right on the bottom.

2) What's the shallowest you've caught fish in, in deep water

Welfare hole a couple years back no one was catching fish and should have been so I shallowed up to about 5 foot and wore them out. Think I was in 22-24 FOW
