Yellowstone Park 9-18-12

Some storms were in the area this last weekend, and we got some reports of good responses to Firehole BWOs during overcast conditions. Other than that, terrestrial patterns most likely are your best bet during daytime. With a bright atmosphere one must be stealthy, so long floats especially to the opposite bank, fly first would be the best strategy on such crystal clear waters as Slough Creek,  Soda Butte Creek,  Bechler River, Fall River, and Boundary Creek.  Other choices for good fishing would be the morning trico mating-spinner fall activity on many of the Park waters or  early or late in the day streamer fishing in waters where brown trout are stocking up and beginning spawning migrations.
