If it were me. And I'm still learning:
Add large adult forage fish. In the south we use bluegill, but you should use what works in your climate. Check local hatcherys. The sooner the better as your breeding season is short.
Do not stock small fish or minnows. The hatchery will try to sell you some. They will just become quick happy meals for the bass.
Add structure. This is easy. Sink stuff.
Find ways to enhance habitat. Things like gravel spawning beds.
You may need to cull some of the bass to let the forage fish get going.
The real smart move is to get help from a guru. It'll cost, but an expert can evaluate your water quality and develop a smart culling program. I'd email Bob Lusk and see if he knows anybody up there.
And be sure to read Pond Boss Magazine. Full of stuff that helps.
