From the benchWith afternoon thunderstorms in the forecast, make your best fishing happen before noon — the Middle Provo is fishing more consistently right now, so focus your morning session there in the deeper seams and runs using a tight-line nymph setup with a small tungsten fly to get down quickly at 242 CFS. If storms roll through and clarity drops, switch to a larger, flashier nymph like the Silver Bullet or Frenchie and slow your drift way down, targeting the slower inside edges where trout will stack up out of the turbid main current. Evening sessions on the Lower Provo can be exceptional if the water stays clear — work the grassy banks with an ant or caddis dry and be stealthy, as these fish have seen pressure all season.
