From the benchWith temps hitting 87°F and bright sun forecast for Sunday, fish the shaded banks and canyon walls from first light through 10 AM before the heat pushes fish deep. When the hopper bite turns on mid-morning, work your fly within 12 inches of the bank — the closer the better — and resist the urge to mend aggressively, as too much line movement will drag the fly off the bank seam. If you see a refusal on the hopper, immediately drop a Frenchie or Juju Baetis on a short tippet off the bend and let it sink naturally; those refusals often mean the fish wants something just below the surface. Keep an eye on the sky Sunday evening and Labor Day — incoming showers can trigger a short but intense BWO and caddis flurry right before the storm hits.
