The caldera stretch (between Chittenden Bridge and the limit below fishing bridge) of the Yellowstone River remains the most productive fishery, and the best dry fly fishing in YNP. Strong spinner falls of Grey Drakes along with caddis, pmd's and terrestrials continue to bring fish to the surface here. Mornings have been your best bet to find dry fly targets. Though, good opportunities remain throughout the afternoon if you're willing to hunt for them. 

Strong thunderstorms last weekend brought muddy water to the Lamar River and Soda Butte Creek limiting the already reduced fishing options in the northeast corner of YNP. Flows remain slightly elevated and off color, but should be back to fishable levels and clarity by the weekend. Slough Creek remains a clear option with good dry fly fishing in the mornings. 

Cooler, wetter weather over the past several days has given park fisheries some much needed relief from hot dry conditions. However, Hoot Owl restrictions are still in place for the Lamar River, Soda Butte Cr and Slough Creek.

The following Yellowstone National Park rivers and streams will close to fishing daily from 2 p.m. to sunrise the following day due to predicted warm-water temperatures and unprecedented low river flows.

• Lamar River downstream of Cache Creek to its confluence with the Yellowstone River.
• Soda Butte Creek (the entire creek).
• Slough Creek (the entire creek).
• Yellowstone River from Tower Junction north to the park boundary.
• Gardner River downstream of Osprey Falls north to the park boundary.
• Snake River from Forest Creek south to the park boundary.

FORTUNATELY, WATER TEMPS COOL QUICKLY OVER NIGHT AT THIS HIGH ELEVATION ALLOWING FOR FISHING DURING PART OF THE DAY - SUNRISE TO 2:00PM.
