Rainbow Trout
Rainbow trout fishing near Harlem, Montana, centers around the Milk River and its tributaries, along with several smaller reservoirs and irrigation canals. While the Milk River can be challenging due to its fluctuating water levels and silty conditions, it does hold trout, especially after periods of stable flow. Spring and fall are generally the best times to fish for rainbows, as the water temperatures are more favorable. Consider fishing the smaller creeks that feed into the Milk River; these often have clearer water and more consistent flows. A good tip is to use attractor patterns like Stimulators or hoppers during the summer months when terrestrial insects are abundant. Be aware of access regulations, as much of the land along the river is privately owned. The rainbow trout in this area tend to be wild and wary, so a stealthy approach is essential.
