Rock Creek headwaters originate from three-Mountain Ranges. The North Fork of Rock Creek and the West Fork of Rock Creek originate from the Sapphire Mountain Range. The East Fork of Rock Creek and the Middle Fork of Rock Creek originate from the Anaconda Mountain Range and the Anaconda – Pintler Wilderness Area. The Upper Willow Creek originates from the John Long Mountains. There are numerous small streams flowing into Rock Creek on its journey north to its confluence with the Clarkfork of the Columbia River. In the 1980’s Rock Creek contained roughly 2,000 Rainbow Trout per mile of stream in the lower 28-miles of Rock Creek; from Gillies Bridge downstream to the mouth of Rock Creek. In the 1990’s the Rainbow Trout population in Rock Creek plummeted to just 300 Rainbow Trout per mile of stream. This drastic decline in the Rainbow Trout population was caused by Whirling Disease and by the Montana Department of Fish, Wildlife and Parks decision to halt the stocking of Hatchery Rainbow Trout into the East Fork of Rock Creek Reservoir. To this day there has been no significant increase in the Rock Creek Rainbow Trout population. However, the Native Westslope Cutthroat Trout population in Rock Creek has rebounded somewhat to fill the void of lost Rainbow Trout population. Also the non-native Brown Trout population is on the increase. The Rock Creek fishery consists of native Westslope Cutthroat Trout up to 24-inches in length, native Bull Trout up to 36-inches in length, native Mountain Whitefish up to 24-inches in length, non-native Brown Trout up to 26-inches in length, non-native Rainbow Trout up to 24-inches in length and non-native Brook Trout up to 14-inches in length.
