Famosa Slough Nutrient TMDL

Introduction

Excessive loading of nutrients into Famosa Slough promotes excessive algae growth and depletes dissolved oxygen levels. These changes limit the ability of this water body to support its beneficial uses designated in the Water Quality Control Plan for the San Diego Basin (9). Famosa Slough was placed on the Clean Water Act (CWA) section 303(d) list of impaired water bodies in 1990 due to eutrophic conditions identified by excessive algal growth. To address the impairment a Total Maximum Daily Load (TMDL) is under development to assess conditions and develop a strategy to improve water quality.

Famosa Slough is an estuary located along the San Diego River in the City of San Diego and is one of the only remnants of a historically large wetland that once encompassed the San Diego River floodplain and Mission Bay. This 37-acre wetland, located within a highly urbanized area, provides habitat to shorebirds and wildlife and offers opportunities for environmental education and public recreation.
