Gerber Reservoir is an irrigation impoundment created by Gerber Dam. It is located in southern Klamath County, Oregon, United States. The reservoir covers . The dam and reservoir are named in honor of Louis C. Gerber, an early pioneer who owned much of the land flooded by the reservoir. Today, the reservoir and surrounding property is owned by the United States Government. It is administered by the Bureau of Reclamation and the Bureau of Land Management. Gerber Reservoir is a popular outdoor recreation site with two campgrounds along its west shore. History Native Americans occupied sites around what is now Gerber Reservoir for perhaps 6,400 years before the first European settlers arrived in the area.
