I would bring small spoons or spinners, meps, panther martins, rooster tails, blue foxes, kastmasters, ect. I always have more luck with spinners over spoons but know alot of people that love kastmasters so I always include them.
Small curly tail jigs may work well here as well.
I use the smallest Rooster Tail that they make. In murkey water, light green, pink and white produce. But most of the time a brown trout pattern with brown tail is my Rooster tail of choice for Waterton.
