Aquatic Insect Monitoring
Aquatic insects are a particularly good measure of water quality since
many are pollutant sensitive, are readily collected, and can be rapidly
identified. Aquatic insects spend a lifecycle in the same stream section
and therefore give a water quality history that a single water sample
taken at one point in time cannot. FRWA holds an Annual Macroinvertebrate
Day in October to monitor streams of the Watershed on a rotating basis
using the Rapid Bioassessment in Wadeable Streams and Rivers by Volunteer
Monitors developed by Mike Beauchene of the CT DEP. Results are available
on DEP’s website.
Our 2010 results of Macroinvertebrate monitoring in the Massachussetts section of the Watershed can be viewed here.
