The river has played an important role in the history of the area, serving as a water source for the Salinan and Chumash tribes. Today, the Nacimiento River is used for recreational and agricultural purposes. The river is impounded by two major reservoirs, Lake Nacimiento and Lake San Antonio, which provide water for irrigation, drinking, and power generation. The Nacimiento River watershed is also home to several smaller dams and reservoirs, including the Nacimiento Dam and the San Antonio Dam. Recreational activities on the river include boating, fishing, and camping, while agriculture in the area primarily consists of vineyards, orchards, and crop farming. The river's hydrology is affected by droughts and seasonal rainfall patterns.
