fishon,
If you could be a little more specific about your location, you may get information from local people that will save you from driving to the opposite side of the state.
Are you in the North West, North Central, or North East part of Washington State?
Weather permitting and if your in North Central Washington, I'd beline it for Omak Lake on the Colville Indian Reservation and catch some Large Greenbacks! (Lahonton Cutthroats). They average 22" to 24", with larger fish up to 30 + inches swimming around, and you will see them! They are awesome to catch this time of year, and you may just catch the biggest trout of your life.
The water is very slick due to the salinity and the fish are very hard to pick up and hold.
Many areas of this lake are wadeable with mostly fist size small rock. There are large flats that you can walk out 60-80 yards into the lake and only be shin to knee deep. kinda feels like your fishing for bonefish on the flats.
You'll see small to large pods of fish ranging from 2-8 fish approaching from your left or your right, you cast, leading the fish by a few feet, then crouch down, wait for them to approach and start stripping. A fish or two, or three, or the whole damn pod will rush to eat your fly, and the fight is on.
A "Premium" pair of polarized glasses are worth their weight in gold here, and are an absolute must!
Here's a couple of fly boxes filled with some Omak Lake Flies, the second box was photographed and is included in the 2003 article on Omak Lake in Northwest Fly Fishing Magazine.
5-7 wt. rods with a 6wt. rod being perfect, line it with a clear or camo intermediate line, a floating line will also work. Streamers, leeches, and sculpin flies in olive and tan patterns work awesome, and patterns in Redside Shiner (the resident baitfish) in the lake will work.
Don't forget to stop and get a Colville Indian Fishing Permit to fish on the reservation, a small price to pay for the large fish that you'll catch.
There are many other smaller lakes in the area that you can catch all the Brookies and Rainbow trout you want.
Here's a link to the Washington Game & Fish site. In the article under the heading North Central Washington, there is mention of the Lahonton's in Omak Lake. Check out the photo on page 1 showing the average size fish, 3 lbs. Yes! 3 lbs, you'll actually get frustrated after awhile when these smaller fish beat the larger fish in the pods to your fly. Hehehehehe!!! ROTFLMAO!!!!!

If your in another part of the state, someone else will have to chime in and help you out.
Hope it helps and fish on!
