Summary Report, Water Board meeting, June 18, 2003
Conceptual Approach for Developing Nutrient
TMDLs for San Francisco Bay Area Waterbodies, Staff
Report to Water Board,
June 18, 2003
Background:
| Sonoma
Creek and its tributaries provide habitat for a
diverse array of aquatic life, including steelhead
trout and chinook salmon. Excessive
nutrients (nitrogen and phosphorus) have impaired
the habitat value of this river system as they have detracted from the river's recreational and aesthetic value.
Excessive nutrients lead to dense growth of
algae in the water. Algae which can deplete the oxygen needed by aquatic organisms for survival.. Potential nutrient
sources include wastewater discharge, failing septic
systems, agricultural and urban runoff, and livestock.
The Sonoma Creek Nutrient TMDL will examine the nutrient
problem, identify significant nutrient sources,
and specify actions that will lead to solutions. |
