Oyster River Management Plan 2014 Submitted to the Department of Environmental Services By the Oyster River Local Advisory Committee with Strafford Regional Planning Commission Funding Source: This plan was funded by a grant from the Local Source Water Protection Program at the New Hampshire Department of Environmental Services. Oyster River Management Plan 2014 ACKNOWLEDGEMENTS The Oyster River Local Advisory Committee (ORLAC) prepared the River Management Plan with the assistance from the Stafford Regional Planning Commission and the New Hampshire Department of Environmental Services Local Source Water Protection Grant Program. The plan was completed in 2014. Members of the Oyster River Local Advisory Committee include: John Wallace, Vice Chair Barrington Stephen Burns Durham Jim Colbert Durham/UNH Water Richard Horan, Treasurer Durham Jim Hornbeck Durham David Shay, Secretary Lee Tom Falk Madbury Eric Fiegenbaum, Chair Madbury The Oyster River Local Advisory Committee recognizes the professional contributions of Pierce Rigrod, Drinking Water Source Protection Program, and the stakeholders and partners that provided technical and editorial assistance in the development of this document.

An advisory management plan is required by the state program and will be used to help guide river communities to achieve their goals in protecting and managing the valuable resources of the river. The most important resource values to protect include: Serving as the primary water supply for NH’s state university, flagship campus, and the Town of Durham - The surface waters have been a primary source of potable water supply for the Town of Durham and the University of New Hampshire since 1935. Wells associated with the river’s water resources contribute to municipal requirements, as well as the needs of individual landowners. The Oyster River’s relatively high water quality is an important influence on the health of the Great Bay Estuary system. The importance of pristine riparian floodplain along several portions of the river corridor - There are several portions of the river corridor that have pristine riparian floodplains – hundreds of acres in extent. Significant storm events have increased substantially over the past decade, resulting in costly infrastructure and property losses due to flooded and failed culverts. These floodplain areas are extremely important in providing flood storage, keeping losses lower than they would otherwise be. Significant value for the purpose of education and scientific research - The core campus of the University of New Hampshire (Durham) lies adjacent to the Oyster River and the university owns over 200 acres of forested land along the river. These lands and waters, collectively known as the College Woods, are heavily used for teaching and research. College Woods is used by courses in the Department of Natural Resources and the Environment, Thompson School, Biology Program (General Ecology), and the Departments of Biological Sciences, English, and Art. Numerous animal species - The Oyster River and its corridor support numerous animal and fish species, which are rare or vulnerable and have been listed as threatened, endangered, of special concern to the state including osprey, New England cottontail, and the American brook lamprey. The collaborative effort between state agencies and municipalities in order to create a water supply protection reserve - The communities of Dover, Madbury, Durham, Lee, Portsmouth, and the University of New Hampshire obtain a portion of their drinking water from these rivers, and in an unprecedented move in New Hampshire, contributed funds or in-kind support to aid in the establishment of a water supply protection reserve on the Samuel A. Tamposi property. The Oyster River Management Plan proposes a management approach focused on protecting and conserving the river’s many resources, advocating for water quality and quantity to sustain aquatic and recreational uses, protecting riparian and aquatic habitat, and balancing the development of land and water uses for other public needs within the river corridor and watershed. The Oyster River Local Advisory Committee (ORLAC) advocates for the implementation of the Plan and supports integration of its goals and strategies by the corridor communities in their planning initiatives and land use decisions. The mission of the ORLAC is to carry out its duties and responsibilities established by the New Hampshire RMPP (NH RSA Chapter 483:8-a) to protect and maintain the resources, values, and characteristics of the Oyster River.
