Henry’s Fork 5-14-10

The lower river (Warm River on downstream) is at its early season best.  Remember that it is closed from Ashton Dam to Vernon Bridge until general season opening to protect spawning ‘bows.  Here’s the ledger on what is active: BWOs in the PM with overcast conditions being best time.  March browns, same conditions best,  Caddis life cycle patterns and  yellow sallys, any time.  Streamers work well in evenings; concentrate on waters out of the sun and with overhead cover.  Big stonefly nymph patterns should be in your fly box and they will become increasingly important as we move through the next several days.  It’s early to see any adult giant stoneflies.  That’s  also several days away, but when we get word that fish are keying on them, we’ll pass it on as part of this report.
