Silver bass used to provide hours of constant catching at the Nanticoke Hydro discharge, starting just after ice out.
The smaller males were good to eat after filleting the lateral line away, and only fresh. Even after a couple of days being frozen they were less than tasty.
All you had to do was keep moving around in the discharge. When one spot died, move 100 yds and action picked up. Bonus there was bass, walleye, even carp and sheephead
