One of my favorite lures for rivers and streams are small lead head maribou jigs. Bounce them along the bottom, cast so they are carried into undercut banks and jig them. I've even floated them along below a bobber. They are deadly in sizes 1/32 to 1/8 ounce, depending on the flow.
Black, white, brown, and olive have worked best for me.
Best part is they are cheap, so when you lose one it doesn't hurt. You're not fishing them right if you're not losing some.
