Alamitos Creek or Los Alamitos Creek is a 7.7-mile-long (12.4 km)creek in San Jose, California, which becomes the Guadalupe River when it exits Lake Almaden and joins Guadalupe Creek. Los Alamitos Creek is located in Almaden Valley and originates from the Los Capitancillos Ridge and the Santa Cruz Mountains. This creek flows through the Valley's Guadalupe Watershed, which is owned by the Santa Clara Valley Water District. The creek flows in a generally northwesterly direction after rounding the Los Capitancillos Ridge and the town of New Almaden, in the southwest corner, before ambling along the Santa Teresa Hills on northeast side of the Almaden Valley. Its environment has some relatively undisturbed areas and considerable lengths of suburban residential character. Originally called Arroyo de los Alamitos, the creek's name is derived from "little poplar", "alamo" being the Spanish word for "poplar" or "cottonwood".
The Alamitos Creek banks were inhabited by Native American tribes thousands of years ago and up until the time of Spanish exploration. Evidence of middens and traces of that hunter-gatherer civilisation has been recorded from archeological excavations and surface finds. From the mid-19th century until the 1970s, operation of the New Almaden Quicksilver Mines discharged high levels of mercury into the creek near its headwaters and the remaining piles of exposed mine tailings still contaminate the creek beyond natural levels. Warning signs to not eat fish caught in the Alamitos Creek still run the length of its course. In the 1940s and 1950s, rapid residential development expanded into this portion of the Almaden Valley including building which encroached into the 100-year floodplain. The Santa Clara Valley Water District began studying this watershed with emphasis upon flood control functions, and made some minor streambed alterations such as energy dissipators. In 1976 the District developed a comprehensive flood control plan and retained Earth Metrics Inc. to prepare an independent Environmental Impact Report. The resulting study developed the first comprehensive data base of biology, water quality, geology and cultural resources information for Alamitos Creek. In 1989 the city of San Jose undertook an analysis to create a creekside trail from Almaden Quicksilver County Park to a location along Alamitos Creek about .6 mile below the confluence with Arroyo Calero.
