The gulper event on Hebgen Lake remains the best still water fishing in the region. The gulper event on Beula Lake in Yellowstone Park is also very good. Gulper activity happens on any still water when callibaetis mayflies emerge in abundance. Sand Creek Pond #4, Elk, Wade, Springfield, and Horseshoe Lakes can host good ones, but timing is important because these can vary in time water for water. On some of these, good emergences begin in Mid-July, on others gulpers last well into September. Also time of day can vary. The famed Hebgen event happens during AM hours, but on other locations afternoons offer the best gulper fishing. Forget about gulper fishing anywhere when wind comes up, and we have had plenty of that this season.
