Notes
This segment of Meyers Valley Creek was evaluated in 2014 and degraded biology was identified and added to the Impaired Waters List. Assessments during the 2020, 2022, and 2024 listing cycles showed phosphorus levels were found to be too high for healthy aquatic communities, like plants, fish, and bugs. Total phosphorus was added as the pollutant for this water on the Impaired Waters List in 2020.Pollutant
