Secrets of the Stream

8/24/2014 | Castlewood State Park | Ballwin, MO

It is hard to tell if a stream is healthy, so how do scientists do it? They test the waters and examine the critters living there. Come find out about water quality testing and macro-invertebrates, the tiny animals living in the stream.  Reservations are not required for this program, which is designed for families.
