Flows are at 72 cfs and gin-clear, requiring stealthy approaches, long fine leaders (12-14 ft to 6X-7X), and precise drag-free drifts. Midges and Baetis are the primary hatches, with terrestrials productive mid-morning through early afternoon and Mahogany Duns expected in the afternoon.

The Owyhee is running gin-clear and extremely low at 58 cfs, demanding long fine leaders (12+ ft) and precise drag-free presentations. Early morning and evening windows are critical as midday heat pushes fish deep; big browns are holding in shaded undercut banks.
