Join us as we test the water quality in High Park’s wetlands. With Water Rangers freshwater test kits, we will check common water quality indicators like oxygen levels and salinity. Participants will learn about the different animals that call High Park home and how changes in water quality can impact wetlands and aquatic ecosystems.

Price: Pay what you can ($0, $5 or $10)
