St. Joe River

About St. Joe River

The St. Joe River in northern Idaho is a substantial waterway, stretching 140 miles from its headwaters in the Bitterroot Range down to Coeur d'Alene Lake. This river is characterized by clear, cold water, a defining feature for its native trout population. The upper 60 miles, designated as part of the National Wild and Scenic River system, offer a wilder experience with whitewater sections particularly during the spring melt. Below Avery, the river widens and slows, becoming more accessible for different types of angling. The riverbanks are often forested, with structure like inlets, drop-offs, and submerged timber providing prime holding water for fish. Access points are varied, including campgrounds like Shadowy St. Joe and numerous trails along the basin, allowing for both shore fishing and boat access in the lower, more navigable sections. This river is home to a robust population of native Westslope Cutthroat Trout, a unique catch-and-release opportunity. You'll also find Largemouth Bass, Smallmouth Bass, Northern Pike, and Yellow Perch, along with Mountain Whitefish. While specific hatch charts aren't detailed here, expect aquatic insects to be a primary food source. When targeting cutthroat, try Stimulators, Elk Hair Caddis, or small terrestrial patterns like ants and beetles, especially during the warmer months. For bass and pike, larger streamers, poppers, and baitfish imitations will be effective. Work the current seams, pools, and areas with visible structure. Early mornings and late evenings often bring fish closer to shallower areas, and the transition zones where the river enters Coeur d'Alene Lake can be particularly productive. Be mindful of other anglers and boaters, especially in popular access areas.
