In mid-August, fishing conditions improve with cooler water temperatures in the Yellowstone River, allowing for successful nymph and streamer fishing. Paradise Valley’s spring creeks and Yellowstone National Park also present good opportunities, especially with hoppers in the afternoons. Alpine lakes offer exceptional trout fishing, requiring careful preparation and stealthy techniques.

Spring fishing in Yellowstone Valley is thriving as river temperatures approach 50°F, awakening trout. Anglers can target rainbows with nymphs and dry flies, especially in mid-afternoon.
