Ohio’s Online Virtual Watershed Tour

What is a watershed? What are the components that make up a watershed? These seem to be simple questions, but many people don't know the answers. In this very basic introduction to watersheds prepared by Ohio State University Extension, these and other questions are answered in interesting and fun ways. The Virtual Watershed Tour Exittakes you along the entire length of an imaginary stream, from its headwaters all the way to the Ohio River.
