Twice each year, GRNA monitors several sites along the 3 major streams running through the natural area to assess the health of the waterways. Every year, new volunteers are trained to help collect this data and contribute to keeping GRNA's creeks healthy. If you're interested in learning how to collect this data, please pre-register by email to Emily@grassriver.org. Please note: masks must be worn inside the Grass River Center.
