spawn mode creates additional opportunity for anglers. But, the Bitterroot’s fish get smart quickly, figuring out which dry flies bite back. That’s why my guides closely watch the water temperature in other nearby drainages, such as the Black-foot, Rock Creek and the Clark Fork, so they can take advantage of trout that haven’t been overly educated or had a barbed T-Bone sunk into their jaws. WARMING BLUE WATER ON THE BLACKFOOT The Blackfoot River is one of our options for escaping the spotlight. We like it best when it is low, clear and “Blackfoot blue.” Lower flows mean there’s less water volume to heat, and on warm, sunny days an afternoon temperature spike creates a nice afternoon feed window. On the Bitterroot, those conditions can detrimental to fishing, as those magical spring days are beautiful for a float but sometimes remarkably bad for the fishing. Those conditions often drive the fish deeper and they shy away from the dry fly. On the Blackfoot, however, which doesn’t see the pressure that the Bitterroot receives, the fish stay aggressive to the dry. And that clear and bluish water also allows us to drive nymphs through medium-depth riffles that connect to deeper holding water. Part of the appeal are the Blackfoot’s trout. You’ll catch lots of rainbows and cutthroats and some l
