Who lives under the rocks in streams and what can these organisms tell us about water quality? Join the Community Science Institute (CSI) for an evening or afternoon at one of our scenic local State Parks as we explore the aquatic life that can be found in the creek and collect a sample of organisms that will be used to evaluate water quality and ecosystem health. This event is meant for the whole family and is interactive. Participants will help us wade through the creek to find organisms under rocks for everyone to look at under magnification. Learn to identify what you find and what these organisms indicate about  how healthy a stream is. Those who are interested in following the scientific protocols for collecting an official sample (that will be analyzed and the results of which will be included in CSI’s long-term datasets of water quality) can help collect the sample and complete a physical survey of the stream. Bring a picnic dinner or lunch along, if you’d like!
