Guided Tour of South OC BMPs Addressing Bacteria Loads

Significant progress in BMP implementation to address the Bacteria TMDLs has resulted in improvements to coastal water quality.

Bacteria Total Maximum Daily Loads

The  Twenty Beaches and Creeks Total Maximum Daily Load (TMDL)  includes creeks, creek mouths, and beaches within the South Orange County Watershed Management Area (SOC WMA). The  Baby Beach TMDL  includes Baby Beach, a small man-made beach, approximately 600 feet wide, located in Dana Point Harbor in Dana Point, California. The goal of the Bacteria TMDLs is to limit bacteria load into impaired waterbodies and to restore the REC-1 beneficial use. For more information on the background of these TMDLs, see the  2019-2020 SOC WMA TMDL Annual Reports here .

Effective Best Management Practices

Since the 2002 baseline TMDL year, the Permittees have implemented various effective  Best Management Practices (BMPs)  including jurisdictional source control programs, distributed structural BMPs, and regional structural BMPs throughout the SOC WMA. These non-structural and structural measures have resulted in improved receiving water quality and reduction in dry weather urban runoff, reducing bacteria loads to listed segments.

This story map travels through each of the subwatersheds within South Orange County Watershed Management Area to explore implemented BMPs that have improved water quality at our beaches and creeks.
