Water Ways: Stream Ecology and Monitoring

Interstate Commission on the Potomac River Basin

What better way to learn about stream ecology and water pollution than to collect and identify the fascinating insects, crayfish, and shrimp-like scuds living in streams? ICPRB provides presentations, hands-on activities, and resources to help teachers (middle through high school classes) start stream ecology or monitoring programs. The presentations can be done as a series or as stand-alone lessons.

Bilingual lessons in English and Spanish are available here.

Overview: Introducing Stream Monitoring

This presentation can be used to introduce stream ecology and stream monitoring to students.
