Trout Fly Fishing Trips The desert lakes and rivers of the Columbia Basin in Eastern, WA offer the fly angler a tremendous opportunity to target quality rainbow, brown, cutthroat and tiger trout. These fish average 16” to 18” with plenty of fish over 20”. The majority of the lakes we fish are considered quality waters and allow for the use of flies and lures only and catch and release angling. Big days can be had on these lakes and it’s not uncommon to catch several hard fighting trout per day. Jeff Nemeth and Lower Columbia Fishing Company are still water fly fishing experts and have over 20 years experience in fly fishing these waters. Whether you’re new to fly fishing or have been doing it for years, you’re sure to enjoy a day of trout fishing with Lower Columbia Fishing Company.
