PRWC Invites Volunteers for 18th Annual Macroinvertebrate Survey

*NOTE Must take Macroinvertebrate Survey Training to participate (see in events)


Pomperaug River Watershed Coalition (PRWC) is seeking volunteers to participate in collecting samples of macroinvertebrates, or ‘river bugs,' from their local waterways to assess stream health. PRWC’s Annual Macroinvertebrate Survey is part of the Stream Riffle Bioassessment by Volunteers program (RBV), a statewide volunteer water quality monitoring program coordinated by the DEEP Volunteer Water Monitoring Program.


Prior to the in-field survey, PRWC is hosting an hour-long Macroinvertebrate Training and Information Session (Location TBD) on Tuesday September 12, 2023 at 6:00 PM. This training and information session is both for those interested in learning more about the RBV program and for those interested in volunteering for the field collection survey. The session will cover what macroinvertebrates are, why they are collected, and how to follow procedures established by CT DEEP.


Trained volunteers will then work directly with PRWC staff to survey a small stream and brook in the Pomperaug Watershed and identify what was collected. Teams will complete voucher samples and data sheets to be submitted to DEEP for verification and inclusion in their larger statewide assessments. Depending on the types of macroinvertebrates that volunteers find in a stream, the CT DEEP can assess it as a healthy stream.


Trained volunteers can choose to join PRWC’s survey for a 2-hour time slot on one or all of the dates listed above. Volunteers will receive more information on sampling locations and time slots following the September 12th training.


Survey sessions will go on in light rain, but in the case of high streamflow conditions, downpours, or thunder, field sampling may be rescheduled. Adults and children over age 10 (with an adult) are welcome to participate in the survey. Dress to wade in the water - old sneakers, rubber boots or waders are recommended, please no open-toed sandals.
