Guadalupe Reservoir

Reservoir Levels Weather Hydrology

Guadalupe Reservoir in California was constructed in 1959 and is located in the Santa Cruz Mountains. The reservoir is fed by the Guadalupe Creek and is a part of the Santa Clara Valley Water District's water supply system. The hydrology of the reservoir is largely dependent on surface flow from the creek and snowpack providers in the surrounding mountains. The reservoir provides water for agricultural and recreational purposes, including irrigation and fishing. However, due to the ongoing drought in California, the water level in the reservoir has been lower than usual, affecting its ability to meet the water needs of the surrounding communities. Additionally, the reservoir has experienced issues with algae blooms and contamination in recent years, leading to temporary closures for recreational use.
