Biological monitoring of water in Minnesota

Biological monitoring measures and evaluates the condition of biological systems—using fish, macroinvertebrate, or plant communities to assess the health of rivers and wetlands. Biological monitoring aims to distinguish between naturally occurring variation and changes caused by human activities. To ensure the integrity of surface waters, we must understand the relationship between human induced disturbances and their effect on aquatic resources.

Biological monitoring is often able to detect water quality impairments that other methods may miss or underestimate. It provides an effective tool for assessing water resource quality regardless of whether the impact is chemical, physical, or biological in nature.
