Volunteer River Herring Monitoring at Beaver Dam Brook and Manomet Brook

It has been a slow herring count season this year, so massive thanks to all those hardworking volunteers recording those important zero counts! Thus far, our volunteers have seen eight fish pass the second (iron) bridge - 5 fish on May 1st, and three single fish on May 12-16. We spoke to the Town of Plymouth, thinking there might be passage problems at White Horse Beach again, but it's clear, and the Town reports a slow year at Town Brook as well. One point for optimism is that the counts were low four years ago, in 2021, so this could be a less vigorous year class, and we might see a recovery next year. Keep counting - one week left!
