Howland Dam Fish Bypass

Dams in the Penobscot River have prevented fish passage from the Gulf of Maine for centuries. To restore connectivity, the Penobscot River Restoration Trust built the largest nature-based fish bypass channel in the United States. This project will help restore Atlantic Salmon populations, and the cultural heritage of the Penobscot Nation.  The nature-based fish bypass contains pool-and-riffle features and natural substrates to support wildlife passage. This project was also connected to local riverfront trails and enhances recreation opportunities. This bypass structure also minimizes operations and maintenance costs.
