Streams in the northeast corner of the park are now in good fishing shape ( green drakes, sallys, PMDs, caddis). Slough Creek and the Lamar River are a bit high but clear. The lower end of Soda Butte will be the most crowded. A bit high will be a good situation in all waters considering the hot weather predicted for the coming week. Avoid fishing the Firehole below Old Faithful to give the already heat stressed fish a break.
