THE STREAM STUDY
The Stream Study is based on material developed by the Save Our Streams Program of the Izaak Walton League of America
The Stream Study provides a method to determine the water quality of a stream based on the collection and identification of stream-bottom macroinvertebrates.
Macroinvertebrates are animals that have no backbone and are visible without magnification. Stream-bottom macroinvertebrates include such animals as crayfish, mussels, aquatic snails, aquatic worms, and the larvae of aquatic insects.
