Additional Information

The Chollas Creek Watershed is located south and east of downtown San Diego in a highly urbanized portion of San Diego County. The watershed drains approximately 30 square miles via two main tributaries, the North Fork and the South Fork, and discharges into San Diego Bay. Except for the downstream 1.2 mile tidal prism area, Chollas Creek is an ephemeral stream which usually only flows during rainy conditions. The map below highlights the Chollas Creek Watershed boundaries, jurisdictional boundaries of the responsible agencies, and the City of San Diego's community plan areas.

A TMDL is a "pollution budget" for an impaired waterbody, such as Chollas Creek. A TMDL defines the maximum amount of a pollutant the waterbody can safely receive while meeting the water quality objectives identified in the San Diego Basin Plan. There are four adopted TMDLs for Chollas Creek: the pesticide (diazinon) TMDL, the dissolved metals TMDL (for copper, lead and zinc). In addition, a draft TMDL for indicator bacteria is currently being revised. This Implementation Plan is designed to meet the requirements of the metals and bacteria TMDLs over the 20 year allowed implementation period. The Implementation Plan uses an integrated approach to achieve this goal.
