| 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. |

| 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. |
