Uvas Reservoir is an artificial lake located west of San Martin, California in the United States. The reservoir is surrounded by a 626-acre (253 ha) park managed by the Santa Clara County Parks and Recreation Department. The park provides limited fishing ("catch-and-release"), picnicking, and hiking activities. Boating is not permitted in the reservoir.
The reservoir sits atop part of the Franciscan Formation, which also comprise much of the Foothill region's rocks to the east of the San Andreas Fault. A variety of rocks from the formation can be found there, including slate, basalt, marble, and many others.
The reservoir was created in 1957 by the construction of the Uvas Dam across Uvas Creek in the southern part of Uvas Valley. It is the fifth largest reservoir owned by the Santa Clara Valley Water District.
