2017 Nequasset Fish Count

Thank you to all 2017 Fish Counters!

Your counting this year helped to estimate the fish population so that the sustainable harvest of alewives at Nequasset can continue for years to come.

2017: A decent harvest with relatively few in the lake

The 2017 alewife run got off to a slow start, with the first fish entering the lake on May 10th.

The Numbers:


May 10 -June 7, 2017


767 bushels/ 92,040 fish

2017 Timeline:

4/27/2017 – No fish yet.  The water temperature is 47, and the water is flowing high over the top of the dam due to all the rain we’ve been having.  The denil baffles have not yet been put in the ladder.

5/2/2017 – Still no fish.  Water temperature is 50.  The baffles are in place, and the flow is still high.  No fish are visible in the pools below the dam, but the osprey is back, sitting on its typical perch.

5/5/2017 – Fish were seen below the ladder!  The water is too cold and is flowing too fast for the fish to climb the ladder, but a bushel or two were harvested today.

5/8/2017 – Water temperature is still 50, and the water is high after the rain today and over the weekend.

5/9/2017 – The water temperature was 52 this afternoon and some fish were swimming below the ladder.  When I stopped by in the evening, there were 2 herons, 2 ospreys, and about 40 gulls.

5/10/2017 – Today’s the day!  The 2017 Nequasset Fish Count starts today.
