Supporting Alewife Restoration in the St. Croix River Watershed - Anadromous Fish Counts at Milltown Dam - 2019


Aquatic Ecosystem Health

Project Description

Anadromous fish have been counted at the research trap at the Milltown dam fishway since 1981. This project forms the basis for measuring the progress of current international efforts to restore sea-run alewife, blueback herring, and American shad to the St. Croix River watershed. It also plays an important role in supporting and validating alewife population models currently in development to support alewife restoration planning. The IWI program continues to provide support for the fish count in partnership with the efforts of governments, the St. Croix International Waterway Commission and the Passamaquoddy Tribe and Peskotomuhkati Nation.  This project is also highlighted in our IWI project StoryMap here.
