About Chesbro Reservoir

The Chesbro Reservoir was formed from the damming of Llagas Creek. The area was frequented by the Mutsun Ohlone Indians for thousands of years before the arrival of the Europeans. Today's reservoir was once part of two Mexican land grants from Mexican Governor Figueroa. The 8,927 acre Rancho Ojo de Agua de la Coche ("pig spring") was granted to Hernandez in 1835 and the 22,283 acre Rancho San Francisco de las Llagas (St. Francis of the wounds) was granted to C. Castro in 1834. The ranchos were eventually acquired by Martin Murphy, an early pioneer of Santa Clara County. By 1860, the lands had been patented to his grandson. The construction of Chesbro Dam in 1955 was part of a countywide effort by water officials to ensure adequate water supplies for the valley's growing population. The new reservoir was named for Elmer J. Chesbro, a local doctor who was president of the South Santa Clara Valley Water Conservation District at the time of its construction. The reservoir which captures water from the Llagas Creek watershed, is used to recharge supplies in underground aquifers to provide water to be pumped from wells for residential, agricultural, and industrial uses.
