Hodgson Brook is a small freshwater stream that flows through the heart of Portsmouth, New Hampshire. The brook originates in uplands west of the city and continues easterly to North Mill Pond, which empties into the Piscataqua River. Over time, local land uses and urbanization have degraded the brook's physical, chemical and biological state. In many places the brook is hidden from public view and enjoyment due to development and restricted access. Because of the brook's pollution problems and low visibility, it has been largely ignored, neglected, and forgotten.

The Hodgson Brook Restoration Project began in response to concerns expressed by local residents, city officials, and businesses. In 2001 the Advocates for North Mill Pond (ANMP), a group of citizens working to protect North Mill Pond, was awarded a grant from the N.H. Department of Environmental Services (DES) to study Hodgson Brook and develop a restoration plan. The ANMP put together a Local Advisory Committee (LAC) now referred to as the Hodgson Brook Advisory Board (HBAB) to help implement the restoration plan. The Watershed Restoration Plan for Hodgson Brook was published in June 2004. Its actions are designed to be implemented at the local level by citizens and others concerned about the brook's health. Many exciting activities are planned! Use this web site to learn more about the project and discover how you can participate.
