One year up bear hunting in Quebec, I was near a river with a small waterfall. I'd hunt until dark (around 10pm), go to the cabin, make dinner, then about 12am I'd fish. Casting lead head jigs with plastic twister tail, and bouncing them on the bottom caught me either a fish (small walleye), or a snag almost every time. Lost all my jigs, caught a lot of fish.
Live bait is always a good option. Walleye tend to stay near the bottom, and bite best at night. You want to run your jigs and lures deep, let them bounce off the bottom. You will lose some, but will catch fish if they are there. If there are pike, big, fast spoons and plugs work well. The DareDevil red and white spoon is a classic pike lure. Pike also respond well to live bait - big minnows and suckers. Don't rule out night crawlers either...They are deadly on Brook Trout that inhabit lots of small streams and ponds up north.
Good luck
