Status of the Watershed Reports

Click for more information on the current status of the watershed!

This year the Status gave not only an overall watershed letter grade but gave letter grades for each sub-watershed and each individual site being monitored. Volunteer efforts from 2012 through 2018 represents more than 3,400 monitoring events across the basin and provides the essential testing data for the 120 lake and stream sites evaluated for this assessment.

Each site can be viewed on an online map and, with a click, the letter grades for 2018 monitoring, improvement over the last 6 years and an overall grade will popup. In addition, the actual test results will display for the primary metrics of water quality such as water clarity, dissolved oxygen levels, aquatic invertebrates present, and laboratory-tested nutrient levels of phosphorus and nitrogen for 2018 and the last 6 years.
