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.
