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. |
 Floating mats of algae indicate excessive nutrients in Sonoma Creek. |
