Santa Fe River watershed

The Santa Fe River in New Mexico is fed by an extensive network of tributary arroyos; these define much of the landscape of Santa Fe, New Mexico and surrounding areas. Together, the river, arroyos and aquifer they supply through infiltration comprise the Santa Fe River watershed.

Besides drainage, the arroyos provide a network of pathways for recreation and exercise when they are dry. Health of the hydrologic basin and associated habitats within the local ecosystem is promoted by the Santa Fe Watershed Association (SWFA).
