Flows & Water Conditions: Good

Clarity: Fairly Clear

CFS: 24

Fishing Report & Conditions: Good - Very Good

Caddis are starting their migration at 7 AM, while the female Trico emergence is picking up steam. The Trico spinner fall and the early PMD hatch start around 9-10 AM, but the strength of PMD hatch is dying rapidly each day. Trico spinner patterns will work through midday. Midday we’re seeing a reappearance of the #12-14 Drakes and the tiny BWO #22-26. Late afternoons and evenings hold Trico hatches, Caddis egg-laying, and Caddis emergence. With the dropping of flows the bird predation is getting worse in shallower water, so expect the fish to move under the banks and weed beds.

  • Dries: Upright Organza Trico #18-22 | Spider Variant PMD #16-18 | Mimic May PMD #16 | Brooks Hot Creek Caddis #18-22 | Baby Boy Hopper #14-16 | Spent Wing Caddis #16-20 |
