Not exactly a "lure" but I've had a lot of luck with powerbait and a really small salmon egg hook. Another option I've had luck with is a small inline spinner with a small rubber trout body (got it at walmart, not sure what its called).

One more good option (again, not sure what its called sorry) is a spoon type thing I learned about from someone fishing next to me on the river one day. I went and picked one up at the local tackle shop from remembering what it looked like. The simple description is it looks sorta like a paper clip. Basically its a skinny piece of metal, bent double with a small gap inbetween. The eye for the line is in the middle of the bend, and it has a double hook (not trebble, double) on the longer of the two "legs" that stick back from the bend. If I see one anytime soon I'll write the name down. Someone else here may know what they are though.
