Map of all Water Quality Sampling Locations

 

The Watershed Center's interactive Regional Water Quality Database for the Grand Traverse Bay Watershed is a storehouse of water quality data for the entire watershed.

The database contains both current and historical data, which has been gathered and entered by groups involved in monitoring water quality throughout the watershed. You can search for data by parameter, location, water body, jurisdiction or specific research document.

Adopt-A-Stream is a volunteer monitoring program that samples aquatic insects and documents stream conditions in the spring and fall.
