Report Summary for Aug 2026
This year: Fishing on the Logan River in the Upper Canyon above State Dam is good, with clear water conditions. Flows are high at 79 CFS, but the river remains in a great fishable range. Anglers should be aware that rain is forecasted in the next 48 hours, which could cause Logan Canyon flows to rise quickly. For effective fishing, Euro nymphing and dry dropper rigs are ideal. Focus your efforts on working through the pocket water and plunge pools thoroughly to find active fish. Evening hours can bring explosive caddis hatches, so be prepared for some exciting dry fly action. Midges are also present. Recommended patterns include the Pheasant Tail Nymph, Zebra Midge, Mercury Midge, Parachute Adams, and Griffiths Gnat.
Best time of day: Evening
Prior years: Fishing on the Logan River is excellent this month. The river is experiencing good flow with clear water, and cool mornings create ideal conditions. Nymphing with small mayfly and caddis patterns is proving very effective. For those fishing along grassy banks, hopper-dropper rigs are also producing strong results. As evening approaches, look for good surface action with caddis and PMD hatches, offering opportunities for dry-fly takes.
