Given that this is Nebraska, I'm guessing that you have Gizzard Shad rather than Threadfin. GShad can occupy a lot of biomass without adding angling value, and their large adult sizes mean that they're difficult to control even with LMB.

Maybe you should consider suggesting a stocking of Musky or Tiger Musky? I know that the Illinois DNR uses Musky to control Gizzard Shad. 63 acres probably won't maintain a reproducing Musky population, but it would not require a lot of money to stock either. Just a thought.
