If I was you and you just want to catch some fish, stop by one of the fly shops in E-Burg, the Evening Hatch is right off the freeway at the Canyon Rd. exit. The shop is in the Flying J truck stop parking lot, you'll see the boats parked in front of it. Just tell the guy that you want to catch some whitefish and I'm sure he'll have some flies to recommend. I would and the copper johns and lightening bugs, they are heavy nymphs with some flash and whitefish love them. Fish them under a little bobber with some split shot to make sure you get down to the bottom. You might catch some nice trout doing it as well. The Canyon from E-Burg to Roza has tons of access and with the river being as low as it is right now you should be able to fish it well from the bank. Remember though that the Yakima above Roza is catch and release only for trout and I'm not sure when it opens for whitefish retention. It is also a selective fishery river so you need single barbless hooks and you can't use bait.
