StreamWatch gathers chemical data from over 40 monitoring sites across the watershed. StreamWatch CATS volunteers monitor one weekend per month and attend a mandatory Quality Assurance session in the Watershed Lab every year.
Volunteers test six basic water quality parameters: water and air temperature, phosphates, nitrates, pH, turbidity, and dissolved oxygen. The results are analyzed and reported to the public through our quarterly subwatershed report cards, municipal report cards, and online. Data is also submitted to the EPA’s Water Quality Exchange.
