Rock Creek Professional Review and Guide
"For many residents of Missoula, the road to paradise begins only 20 miles east of town at Interstate 90, Exit 126—Rock Creek Road. A drive along Rock Creek offers an escape from the sprawling metropolis of 50,000 inhabitants into a wild and beautiful mountain valley. It also provides access to one of the most delightful and challenging fishing experiences in Montana. Throughout its 50-mile length, Rock Creek is a classic fast-water trout stream.
The riffles, runs, and occasional pools host five species of trout, all of which have the agreeable disposition of being where they’re supposed to be. Literally any place that offers hiding cover and some relief from the current will harbor trout. Key species: Rainbow trout, brown trout, cutthroat trout, whitefish, brook trout, and bull trout."
