As is the history of most industrial rivers in the northeast, these runs were extirpated by uncontrolled pollution and the building of dams that lacked fish passage.
Dams alter the chemical, physical and biological integrity of rivers by changing the flow, increasing water temperature, changing the distribution of sediment, reducing oxygenation and blocking the migration of fish and other aquatic species to their spawning or feeding habitat.
