The commission is comprised of 21 members, including members of the New Hampshire House of Representatives and Senate, the Department of Environmental Services, the Pease Development Authority – Division of Ports and Harbors, the Fish and Game Department, the Great Bay National Estuarine Research Reserve, the New Hampshire Estuaries Project, the University of New Hampshire, the Rockingham Planning Commission, the Strafford Regional Planning Commission, The Nature Conservancy, representatives from conservation commissions from towns in the Great Bay Estuary, representatives of water-related recreational interests, and representatives from water-dependent commercial interests. The commission is required to make an interim report of its findings and any recommendations for proposed legislation on or before November 30, 2008, and make a final report on or before November 30, 2009.

At its inaugural meeting on September 12, 2007 the commission elected Representative Judith Spang as chairperson. The commission will hold monthly meetings that are open to the general public.
