Authors: J. Flores, K. Wagner, L. Gregory, J. A. Benavides, T. Cawthon

This document is a comprehensive update to the original Arroyo Colorado Watershed Protection Plan and was written to contain
the U.S. Environmental Protection Agency’s (USEPA) nine minimum elements of watershed plans. The long-term goal of the watershed protection plan is to achieve state water quality standards in the Arroyo Colorado by lowering pollutant loadings, enhancing streamflow and aeration, and restoring aquatic and riparian habitat through voluntary measures and existing regulatory controls.
