Fly Fishing Williamson River Oregon
The Williamson River is about 100 miles
long.Together with its major tributary, the Sprague
River, it provides more than half of the flow into
Upper Klamath Lake, Oregon's largest freshwater
lake. Fly fishing the Williamson River puts you in the
same water as large wild rainbow trout that move into
the river to spawn and to escape the warm Summer
water of Upper Klamath Lake. Smaller numbers of
brown trout also thrive in the Williamson, especially
below Spring Creek. Smaller rainbow trout and
brook trout are present above Klamath Marsh. Much
of the land along the river is privately owned so
public access is limited

north side of Fuego Mountain in the Winema National
Forest. It flows through the mountains and then
through Klamath Marsh in the Klamath Marsh
National Wildlife Refuge. U. S. Route #97 flows
roughly parallel to the river downstream of the
refuge. It picks up Spring Creek at Collier Memorial
State Park. The Sprague River joins it before flowing
into the norther end of Upper Kamath Lake.

Lakes. Fish move into the river as the lakes warm

boats and pontoon type rafts. Most wading is done in
the upper sections of the river. The spring fed

insects, including a big population of Black Drakes.
