Cascade Locks

The Cascade Locks are located along the Columbia River.  The river at this point was originally filled with rough rapids and steep elevation changes.  In order to better navigate this section of the river, the locks were built in a channel next to the main river flow.  The locks are no longer in use because a system of dams now regulate the depth of the water and the rapids are no longer an issue.
