Upper Klamath National Wildlife Refuge and the eastern margins of the Sky Lakes Wilderness meet in this landscape of marshy lowlands and steep timbered ridges. The transition from the high forest of the Winema National Forest down to the watery expanse of Agency Lake is defined by a series of springs and managed waterways, including Crystal Spring and the Sevenmile Canal. These features reflect the complex water management history of the Wood River Valley, where natural sloughs like Fourmile Slough are integrated into a system of canals and levees.
