Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Odana Pond was added to the Impaired Waters List in the 2012 cycle for phosphorus and chloride. Phosphorus levels were too high, reflected in algal blooms. Evaluations every two-year cycle from 2014 to 2024 confirmed the phosphorus and algal impairment.Pollutant
