The Chesapeake Bay watershed is composed of a network of streams and rivers that funnels freshwater from the land into the Bay. Over time, many of these streams have been negatively impacted by human activity, which has reduced the water quality entering the Bay and caused a loss of biodiversity. Watch as CBF Pennsylvania Educator Doug Walters explores a tributary stream and discusses how to evaluate its health.
After watching the video, see if you can identify key factors related to stream health in our physical freshwater stream investigation What Makes A Healthy Stream?" and our biological freshwater stream investigation What Lives in Our Freshwater Stream?.
