Watsonville Slough Pathogen TMDL

Information

Problem Statement - The beneficial uses of water contact recreation (REC-1) and non-contact water recreation (REC-2) are not supported in Watsonville Slough or its tributaries, Struve, Hanson, Harkins and Gallighan Sloughs, because fecal coliform concentrations there exceed existing Basin Plan numeric water quality objectives protecting these beneficial uses.
