The reservoir was created in 1952 following the construction of the Lexington Dam.
The town of Lexington, which was submerged by the reservoir, was a former lumber mill community founded in the 1840s.
The reservoir is owned and managed by the Santa Clara Valley Water District.
The site prohibits swimming and all forms of body contact with the water to protect the public water supply.
The park acts as a southern terminus for the Los Gatos Creek Trail, connecting it toward the downtown Los Gatos area.
Geologically, the reservoir is situated near the San Andreas Fault zone.
Lexington Reservoir County Park is a 950-acre site centered on a large man-made reservoir in the Santa Cruz Mountains. It serves as a regional hub for rowing, fishing, and hiking, featuring direct access to the Los Gatos Creek Trail. The reservoir was created by the construction of the Lexington Dam, which impounds Los Gatos Creek. Recreational activities are restricted to non-motorized watercraft, such as kayaks, canoes, and stand-up paddleboards. The area provides habitat for various bird species, including bald eagles and osprey, often visible near the water's edge. Hiking trails traverse the surrounding hills, offering significant elevation gain and views of the Santa Clara Valley. Visitors utilize the park's boat launch facilities for on-water access. Fishing permits and local regulations govern the extraction of species like rainbow trout and largemouth bass. The reservoir acts as a crucial water storage facility for the Santa Clara Valley Water District.
