Check out photos taken by a MyRWA volunteer of the Upper Mystic Lake Dam Rehabilitation Project. This project addresses safety and flooding issues, as well as incorporates a much needed fish ladder and eel way. The Mystic River supports diadromous fish including alewife (Alosa pseudoharengus) and blueback (Alosa aestivalis) herrings, American shad (Alosa sapidissima), American eel (Anguilla rostrata) and white perch (Morone americana). The Mystic River supports one of the largest alewife runs in Massachusetts, making a passable dam a necessity for these fish to reach their native spawning grounds each spring.
