Beardsley Park Fish Ladder



Each year, alewives and blueback herrings migrate between fresh water and salt water in order to breed, hatch, and live. Due to the height of the dam connecting Bunnells Pond and the Pequonnock River, a “fish ladder” was constructed to aid the annual migration.


The fish ladder allows the fish to bypass the dam by “climbing” over the height of dam. It is believed to be the highest fish ladder in the Northeast.
