Join a team to search for aquatic insects in Rouge streams. Pre-registration required and COVID prevention protocol must be agreed to and followed. Volunteers are pre-assigned to a team and meet at their first of two sites. Children 10 and above welcome with a participating adult; groups of up to six. Data collected is used to track the health of the watershed. A Stonefly Refresher is held prior to the event for those who want to learn more about these insects.
