Shiawassee River Water Monitoring Program
Keepers of the Shiawassee routinely collects samples of the macro-invertebrate population of the river, in a partnership with Genesee County Drain Commissioner, to help evaluate the health of the river ecosystem.
Friends of the Shiawassee’s Stream Monitoring Program is almost identical to our program at Keepers. They have an excellent overview of the program at the link.
We are always looking for volunteers to help and learn on our river monitoring collection days which are usually in spring and fall. The dates can be found on our events calendar. We also post updates on the Keepers of the Shiawassee Water Monitoring Facebook group.
