After 200 years, river herring have been spotted in the Mill River above the Hopewell Mills dam. The Division of Marine Fisheries recently set up a video monitoring station at Reed and Barton, and have been recording a stream of video footage. Many fish use the river, and from what has been reviewed, these fish include yellow perch, chain pickerel, trout and our first river herring!

Because this is a large project that includes removal of three dams and building a fish ladder, it provides a perfect opportunity to study the response of this river system to restoration efforts. Monitoring will continue with each removal, and a monitoring system will be put in place at the fish ladder as well. We will post video when it becomes available, and will continue to provide updates of fish sightings. For now, we are looking forward to seeing the new channel when grass begins to grow.
