Dearborn Brook is a small but important stream located in Stratham and Exeter, New Hampshire. The Brook flows into the Town of Exeter Reservoir and is used to supply drinking water to the Town of Exeter and portions of Stratham. The Dearborn Brook Watershed Committee was established in 2001 to develop a management and protection plan for the Brook. Committee members represent the Conservation Commissions, Open Space Committees, Planning Departments, Water and Sewer Commissions, and Department of Public Works in the Towns of Exeter and Stratham. The purpose of this project was to begin implementing the top three recommendations made in the Dearborn Brook Watershed Management and Protection Plan: protecting undeveloped land, reviewing land use regulations, and developing public education and outreach campaign.
