Yellowstone Park 7-28-17

The giant and golden stonefly hatches are progressing up the Yellowstone River.  Now into September is when terrestrial insect patterns work well on Fall River Basin streams. Streams in the northeast corner of the park are now in good fishing shape. Lamar River, Slough and Soda Butte Creeks offer good dry fly fishing  with caddis, PMD, yellow sally life cycle patterns and those for terrestrial insects bringing action. Be aware that these streams tend to get crowded from now through August.   Some smaller streams in that area offering better solitude, but smaller fish, include Buffalo Fork off Slough Creek, Pebble Creek off Soda Butte Creek, and Cache Creek off the Lamar River. Leave the Firehole River alone until September when cooling air temps will bring water temperatures down to levels where fish can better withstand the rigors of being caught and released
