On Wednesday I went through 2nd cut all the way up to the dam. This was my first time through so I went slow the whole way. I don’t recall seeing many places with depths less than about 3′ except by the main channel. Saw a guy in a flat bottom tiller fly down through.
I do not know the back channel very well yet. With the current water levels it would not take much to find a place to get hung up if your not familiar with the area.
