Gerber Dam and Reservoir, part of the Klamath Project and located on Miller Creek, 14 miles east of Bonanza, Oregon, was constructed in 1924-25. The dam, a concrete arch structure, has a height of 84.5 feet and a crest length of 460 feet. The reservoir capacity is 94,300 acre-feet. It was named after Louis Gerber, an early settler who owned a considerable portion of the site. Gerber Dam and Reservoir provides storage for irrigation and reduces flow into the reclaimed portions of Tule Lake and the restricted Tule Lake Sumps in the Tulelake National Wildlife Refuge.
The Bureau of Reclamation is responsible for the development and operation of the Klamath Project, which provides irrigation, flood control, recreation and fish and wildlife benefits.
Some of the wildlife visitors may see when visiting Gerber Dam and Reservoir are bald eagles, osprey, sandhill cranes, American white pelicans, bobcats, coyotes, antelope or mule deer. Bitterbush, sage bush, Ponderosa pines and Juniper trees are located around the area.
