Walla Walla River in Milton-Freewater, Oregon, with levee on left side and terrace on right side.  Channel is constrained by levee.  Looking downstream.
 

Lower Walla Walla River flowing through agricultural lands in Washington.  River has developed an incipient floodplain (right side) below terrace (left side).  Looking downstream. 
 

Twisp River (tributary of Methow) in Washington.  Large woody debris transported and lodged during a flood event.  See close-up in next photo.  (In upper Twisp River near War Creek campground)
 

Twisp River, Washington.  Scour pool formed under channel-spanning tree seen in preceding photo. 
 
 

Upper Twisp River, Washington.  Wetland formed by beaver dam.
 

Methow River, Washington, downstream from town of Mazama.  Riverside home destroyed by bank retreat during flood.  Structure at left edge of photo is the remaining garage.  Some of house debris is visible on bar just downstream.  Looking downstream. 
 

Rip-rap on outside of meander bend, Methow River, Washington, to protect a rural residential property (house visible in distance).  Looking upstream.  Rip-rap limits migration of outside bank of meander bend and locks channel in place. 
 
Lower Methow River, Washington.  River here is somewhat confined within bedrock benches, but has some space for adjustment.  Note rip-rap on outside bank.  Looking upstream.
