Anyone enlighten me about bank fishin. I am going on a hay run and would like to give it a try. I am proficient at nymph and dry presentsation but dont know where, time of day or which flies to have in my arsenal. I understand the Yak flows have dropped and bank fishing is more accesable. Thanks in advance.

Slab,
Check this out first:

There are some slides that put nice seams in the bank flows. Watch for risers for a spell, then approach with a plan.

Oh, there are rattlers along the banks too so watch where you walk

The water flip flop is usually done by the 10th, so everything from Rosa to Cle Elum will be easily wadable. Just pick your spot.

Another site to check out for patterns, hatches and flows.

Blue winged olive duns and emergers in tiny sizes (18s and 20s), even on sunny days but best on overcast or drizzly afternoons. Last year was a very good year for October Caddis after the middle of September. A size 8 or 10 Elk Hair Caddis with an orange body answers nicely as will any number of October Caddis steelhead waking patterns. Adult October Caddis live for a couple of weeks after hatching and have to come back to the water to drink so you don't have to wait until dark for the egg-laying females to appear.

A large (8-10) orange-bodied, brown-hackled soft hackle will do for an October Caddis pupa. These pupae will swim around in sheltered water for several days before crawling ashore to emerge as adults and represent a large and vulnerable meal to the trout.
