Protecting Northern Michigan's ​Water Resources

Monitoring Programs

Our staff monitors lake and stream water quality to assess impacts from development, agriculture, stormwater, discharge pipes, or other pollutant sources. Monitoring can include physical (e.g., oxygen and pH), chemical (e.g., nutrients and metals), or biological parameters (e.g., bacteria).

We assess the impacts of rivers and streams on lake water quality by concurrently monitoring all or select tributaries flowing into a water body. Water quality data is used to determine pollutant loadings from individual streams, and watersheds are assessed to identify pollutant sources.

We monitor stormwater runoff in urban areas to gauge impacts on nearby lakes and streams. Physical and chemical water quality is monitored at stormwater outfalls to detect dangerously high levels of contaminants, determine pollutant loadings, and more.
