It flows for approximately 10 miles before emptying into the Santa Maria River. Historically, the Huasna River was home to Chumash Native American communities and later became a site for ranching and agriculture. The river's flow has been impacted by drought and groundwater pumping. There are no major reservoirs or dams on the Huasna River, but the Huasna and Arroyo Grande aquifers are major sources of water for the area. The river is used for agriculture, primarily for cattle grazing and hay production, and is also a popular spot for recreational activities like fishing and hiking. The Huasna River is a valuable resource for the local community and an important part of the region's history and ecology.
