Bulletin 160-98 Public Review Draft 003336 Chapter 7. Coastal Regions Water Demands and Supplies Because of the water allocated to the North Coast's wild and scenic rivers, envirorunental water use comprises the majority of the total water demand in the North Coast Region. Water shortages are only expected to occur under drought conditions in the North Coast Region, as shown in Table 7-2. These water shortages will be mostly in the USBR's Klamath Project's service area and some small coastal communities. Table 7-2.

The primary water storage facilities ofUSBR's Klamath Project are Upper Klamath Lake, Clear Lake, and Gerber Reservoir. This project was authorized by the Secretary of the Interior in 1905, and is one of the nation's earliest reclamation projects. The project's primary purpose is to store and divert water for agricultural use. The project service area includes more than 230,000 acres of irrigable lands in Oregon and California. The project also serves four national wildlife areas including the Lower Klamath, Tule Lake, Clear Lake, and Upper Klamath refuges. ""Photo: one of Klamath Project dams from USBR 7-5 DRAFT
