Each spring over 1/2 million river herring migrate from the ocean up the Mystic River to the Mystic Lakes and to Horn Pond to spawn. If lined up back-to-back, this would measure up to 100 miles of fish!
The more we know about the river herring the better equipped we are to advocate for a clean and healthy Mystic River and for this unique species and the wildlife it supports (you can thank the river herring for the return of the Bald Eagles to the Mystic Lakes--they're a great food source for eagles).
YOU are invited to participate in this spectacular wildlife phenomenon by monitoring the herring once a week for 10 minutes.
Volunteer monitors visit the dam from 7am-7pm everyday during the migration season (April-June) to count the fish swimming up the spillway. We send the data they collect to the state Division of Marine Fisheries who use a statistical model to estimate the size of the migration.

STEP 2: Are you monitoring at Horn Pond? Attend this training!
The monitoring season begins on April 1st and runs through the end of June. When you sign up, you are committing to monitor each week during your chosen shift--you only need to monitor for 10 minutes out of that hour. We will provide all the information you need at the training.
