l Toro Creek Watershed is a small semi-arid watershed known to exhibit high transmission loss and produce flash floods. In order to compare land-use types and slope to sediment yields, El Toro Creek Watershed was monitored for suspended sediment and surface runoff in February 2001. Slope, soil type, and land-use sub-basin characteristics were delineated using Geographical Information Systems and used to explain suspended sediment transportation and surface runoff in the watershed. Steep slopes associated with non-vegetated banks exhibited high loads of sediment and surface runoff. Lack of sediment to the lower watershed from upstream depositional areas has produced stream bank failure in El Toro Creek. Revegetation of theses downstream banks would help decrease erosion from creek bed and alleviate flooding in the lower portion of this small semi-arid watershed.
