Calero dam and reservoir

"Calera" is the Spanish word for limekiln or limestone quarry. In 1935, the Santa Clara Valley Water Conservation District obtained land for the proposed Calero Reservoir from the Newman brothers. They had operated a ranch since they purchased the land in 1905 from the Bailey family, who owned 873 acres in what was then known as Calero Valley. Calero dam and reservoir is one of the six original reservoirs approved for construction by voters in May 1934. The dam and reservoir are located on Calero Creek. The reservoir can store 9,934 acre-feet of water. Its surface area is 349 acres.*
