Wild Waters Fly Fishing's Recommended Gear

Description: About Trinity River

The Trinity River is well known as one of California's finest steelhead fisheries. There is 120 miles between Lewiston Dam and the confluence of the Klamath River. Most of the Lower stretches are not easily accessed and this part of the canyon can hold big class v rapids. The middle section of the river is popular fishing for salmon and steelhead and holds some good fly water. It is very scenic as most of the land owned by the USDA. The upper river controlled by Lewiston dam consists of more glide pools and small riffles, great fly water for steelhead. This part of the river is also a great trout fishery. Resident brown trout are caught and will often be 20 inches or larger. The top 1.5 miles of river is designated fly-fishing only with special regulations and has an open season from April 1st through Sept. 15th. This water is protected spawning grounds in the winter but in the summer it’s a fantastic rainbow trout fishery flourishing with what will soon be steelhead.
