Klamath Basin

Lake name:
Klamath Basin
Location:
Oregon
Region associations:
Klamath Basin National Wildlife Refuge Complex; Klamath River; Klamath Tribes; Yurok Tribe
Comments:
A large area of southern Oregon and northern California drained by the Klamath River. The Klamath River originates in the deserts of eastern Oregon and supported major salmon runs historically. The basin includes river, wetlands, reservoirs, forests, and deserts as well as urbanized development and agriculture. There are four major dams for which removal of them is proposed. There are six national wildlife refuges in the basin and it is a major stopover site for birds migrating on the Pacific Flyway. There has been major issues with water availability, water rights, and overallocation of water. Drought has also reduced water levels to dramatic lows in recent years.

Comments:

Appendix D, Table D-2, data is 3164 as area population estimate, population data source is Shuford et al. 2004. A search in Shuford et al. 2004 doesn't give me this estimate for Western grebe adults so I don't know how it is derived or from which date survey this number is totaled from.
