Yesterday park fisheries personnel began treating the Gibbon River to remove all salmonids above Virginia Cascades including Ice, Grebe and Wolf Lakes. Their plan is to eventually introduce fluvial grayling (those now present are adfluvial) and westslope cutts in that section of the drainage including the lakes.

Currently for most of the rivers worth a visit in the park, presenting terrestrial insect patterns brings the best responses from trout.
This time of the season most sources relate that park still water fishing slacks off. This may be true of such as Heart, Lewis, Shoshone, Trout, and Yellowstone Lakes, but it is not the case with Beula Lake. Right now it offers the fastest still water fishing in the park, and likely in the immediate surroundings. To enjoy Beula Lake you must be willing to drive the somewhat rough Ashton-Flagg Road, walk 2.5 miles to the lake, and either wade the shoreline or carry in a flotation device to fish the entire lake. Cinnamon caddis, speckled dun, and damselfly life cycle and small leech patterns are the best for getting responses from resident Yellowstone cutthroat trout. Not many regional fly shops tout this serene lake in the Fall River drainage, but we have “the goods” on it, so get in touch if you are considering a visit to this 107 acre lake.
