Benthic Macroinvertebrate Sampling
Whether in the field or in the lab, our volunteers have fun while monitoring

Information on our Water Quality Monitoring Program
What is Water Quality Monitoring (benthic monitoring) and why do we care about what lives in our local streams? Freshwater benthic macroinvertebrates, or more simply “benthics”, are animals without backbones that are larger than ½ millimeter (the size of a pencil dot). These animals live on rocks, logs, sediment, debris and aquatic plants during some period in their life. The benthics include crustaceans such as crayfish, mollusks such as clams and snails, aquatic worms and the immature forms of aquatic insects such as stonefly, dragonfly, and mayfly nymphs.
These animals that live in the stream have different levels of sensitivity to pollution. Some can live only in water with little or no pollution, but others can exist even with surprising levels of pollution. By collecting them and noting what types and how many of each type are living in the stream, we can get an idea of how healthy the river is. The more benthics we find that are sensitive, the higher the score, meaning the healthier the stream is. We track that information from season to season and year to year, and share it with both local and state agencies. Every Spring and Fall the FRWC monitors 34 different sites in and around Genesee and Lapeer county. Our monitoring process revolves around a specific 300 foot stretch at each stream so that we are consistent in monitoring the same area every time. As part of the process we spend 90 “wet net” minutes collecting at a site. This means that regardless of how many volunteers you have at a site, the total time spent collecting is 90 minutes. So if you have 2 volunteers collecting, you would each spend 45 minutes sampling all the available habitats within the 300 ft stretch.

Monitoring Gilkey Creek
The restored Gilkey Creek easily holds high flows after a heavy rain. The FRWC has contracted with the Applewood Estate to conduct chemical and biological monitoring of the Gilkey Creek to assess the impact of stream restoration activities. We are pleased to note that no significant impact was found during the construction season, and the health of the creek continues to improve as the creek reestablishes in its new course. The reports on our work are below. 2010
Stream Profiling on the Gilkey Creek
The FRWC contracted with the UM-Flint Center for Applied Environmental Research to conduct stream profiling, an assessment of stream bank stability on the Gilkey Creek. Check back here soon to access copies of those reports.
