Macroinvertebrates are a great and simple way to test the water quality of any given stream, river, lake or other water body!

Macroinvertebrates, or aquatic insects, are either adult or larval insects that live in the stream. Some may bury in the streambed, some might hide under rocks, some might even skate across the water’s surface. Different macroinvertebrates have different tolerances to water pollution. Because of this we can use macroinvertebrate surveys to quickly check the water quality in a stream.
