Macroinvertebrate Sampling

Macroinvertebrates are animals with no backbones that are big enough to see without a microscope, such as insects, crayfish, mussels, spiders, dragonflies and worms. Just like people, macroinvertebrates need clean water for survival. In fact, one way to tell how healthy or polluted our waters are is to collect and count the number and types of macroinvertebrates present in our lakes, rivers, streams and wetlands.

This free educational program teaches youth to collect and identify macroinvertebrates with an expert to determine the health of a local waterbody. It is available to school classes and youth groups grades 9-12.
