I have fished the ruby a hand full of times with pretty good success. I always remember doing well. I would do like waterloo says and fish near other fisherman, but you can go just about anywhere and get them. Most people are pretty friendly, especially ice fishing, so just go and spark a conversation and see what that gets you. I love rat finkes, green, orange always work good. Maggots and meal worms and crawler chunks should get some hits. I'd stay in about 8-15 f.o.w. and see what happens. Most of all have fun, if the Reservoir sucks, bring your fly rod and fish the river below, its awesome.
