That makes sense. It’d just be interesting to see the survival rate of trapping and shipping downstream vs going through an inactive dam. Gotta think the truck shipping would be in the 80%+ range if not better. Still would like to know an average mortality rate of passing through the dam. Heard many numbers floated around but nothing too concrete.
