The Winnicut River originates in the marshes and low-lying hills of the coastal plain of New Hampshire, flowing north into the Great Bay estuary. Although relatively small it is a significant tributary to the Great Bay. The watershed has a drainage basin of approximately 17.5 square miles and includes portions of North Hampton, Stratham, and Greenland. The river, its perennial tributaries (Barton Brook, Norton Brook, Marsh Brook, Winniconic Brook, Thompson Brook, Haines Brook, and Packer Brook), and numerous streams account for a total of 46.5 stream miles in the watershed.
The river and several of its tributaries are experiencing the negative impacts of nonpoint source pollution (NPS) due to the rapid development that has occurred within the watershed over the past 20 years. The river and several of its tributaries are currently listed on NH Department of Environmental Service’s 2008 Section 305(b) and 303(d) Surface Water Quality Report as impaired for multiple designated uses, including Aquatic Life, Primary Contact Recreation, and Secondary Contact Recreation.
There is community support to restore and protect this valuable water resource. The New Hampshire Rivers Council created the Winnicut River Watershed Coalition to implement projects on the Winnicut River and to act as the local voice and steward. Projects include a volunteer water quality monitoring program to make current and accurate water quality data available and the restoration and management plan. When the plan is completed and approved, the Council may apply for funds to address water quality impairements in the watershed.
