Flows out of Ashton Dam are 1320CFS, with higher flows below Fall River. The boat ramps are open and there are lots of boats and wading anglers. Please be respectful of others, smile and give each other ample space. The main show has been clouds of caddis, some PMD’s hatching and spinner falls that seem to happen secretly. A good number of Golden Stones are flying around and skittering on the water. Try a Henrys Fork Golden Stone #8 and #10. The EZ Caddis Tan #16 with a size #16 Lawson Partridge Caddis Emerger as a dropper is deadly during the last hour of daylight. Organza Rusty Spinners, CDC Biot rusty spinner and Splitsville Rust Spinners might be the most important flies in your box. Green Drakes are making their annual appearance. Flies like the #12 Lawsons Extended body or the Hairwing Green Drake #10 are popular choices.
