Flow has dropped to 54.3 CFS (gauge height 5.2 ft near Oakley), down significantly from recent weeks, pushing fish tight to undercut banks, deeper seams, and structure — water clarity is high, demanding fine tippet and precise, drag-free presentations.

Hatch Chart

Best Time Window
- 7 AM - 10 AM: Prime midge window — fish the deeper, slower runs with a midge pupa before the sun fully hits the water and fish become more wary.
- 11 AM - 2 PM: BWO hatch peak — watch the flat tailouts and slower glides for rising fish and switch to dry flies or emergers when you see consistent surface activity.
- 4 PM - 6 PM: Late-afternoon caddis and terrestrial window — work the riffles and grassy banks with a caddis dry or ant pattern as temperatures peak near 81°F and fish become opportunistic.
Guide's Tip
From the benchWith the Weber sitting at 54 CFS and crystal clear, your approach matters as much as your fly selection. Stay low, wade slowly, and keep your shadow off the water — fish are stacked in predictable spots like undercut banks and the deepest seam in each run, but they're spooky. Drop down to 6X fluorocarbon tippet for your dry and emerger presentations, and don't be afraid to go 6.5X on the midge rigs. A long, reach cast upstream with a quick mend will buy you the drag-free drift these selective fish demand.
