Water Quality Data

Water Quality Monitoring Locations

Sites for our Water Quality Monitoring Program are selected one of three ways:

  1. Comprehensive stream monitoring: Establishing headwater, mid-length and near mouth sites on the main tributaries, and secondary sites near the mouths of the main feeders to the main tributaries. Collecting consistent data from these sites allows us to better understand and analyze stream-wide and watershed-wide health.
  2. Areas of Concern: Establishing sites nearby current or emerging issues that may impact water quality including but not limited to resource extraction, large-scale agriculture, flooding, and erosion. Collecting data from these sites allow us to help citizens and resource managers assess impacts to water quality and plan for the preservation and protection of important resources.
  3. Volunteer Interest: Establishing sites based on recommendation or intrigue from prospective or current volunteers. Collecting data from these sites supports our vision of having citizens become stewards of their own watershed by giving them the choice to monitor an area they care about or have concern for.

The water chemistry sites included above are the locations of our current Water Chemistry Monitoring Volunteers. The macroinvertebrate sites included above are the locations of sites Macroinvertebrate Volunteers collected samples from in Spring and Fall of 2021.
