Fish counts compiled by MDMR 2013-2024

The Maine Department of Marine Resources has collected fish counts at major fishways across the state, including the Brunswick Dam. Information is available for 2013-2024. The historical trap counts, as seen below, show numbers for Atlantic salmon, American shad, and river herring. To learn more information, visit the MDMR website here!

Scientists associate the years in which American shad counts were unusually high with the Unit 1 Turbine next to the fishway entrance being taken down for maintenance.
