MAINSTREAM RESOURCES

Michigan DNR

Michigan DEQ

USGS Real Time Streamflow

Mainstream Resources has been retained by several private and commercial entities to design and conduct limnological monitoring. 

Limnological data, as they are systematically collected over the long term, will describe trends in water and habitat quality in surface water bodies.  Several water bodies have served as reference stations for this monitoring to aid in tracking differences.    Michigan Department of Environmental Quality/Surface Water Quality staff members have collaborated in the development of these monitoring designs. 

The following pictures are a few collected during the last two years of field work.
