What lives in the river; macroinvertebrates

What in the world is a macroinvertebrate?  Macroinvertebrates are aquatic bugs that we can see with our eye, have no backbone, and live in our rivers, lakes and wetlands.  Discover how these aquatic bugs are special and where to find them.  We will collect macroinvertebrates from Minneopa Creek and identify each of them using a simple identification key. Please at the Falls side of Minneopa State Park.
