In the period before permanent planning and management machinery for the Potomac materializes, the Basin will get much protection against major disruptive change through the continuing interest of Federal and State agencies made aware of its problems during this first-stage planning effort, through improvement and preservation programs already in movement or initiated by this report, and perhaps most of all through aroused and informed public interest. There is room for a broadly based citizens' watchdog organization to keep tabs on Basin affairs and to exert leverage in such critical fields as local planning. It might be formed as a new group or might be built around an existing organization such as the new Potomac Basin Center, whose function has been to comment impartially and intelligently on Basin planning and prospects. Action now In the different chapters of this report, various things stand out that need to be started quickly, either to satisfy looming demands for water development and water quality control, or to restore or protect scenic, ecological, and recreational assets which, if not attended to quite soon, are going to either disappear or suffer irreparable damage. A few recommendations for action on certain of these immediate problems were made in our _Interim Report_ of two years ago, together with recommendation on one or two noncontroversial items clearly not in conflict with any conceivable ultimate Basin aims. In abbreviated essence, the main Interim recommendations, made with Interdepartmental Task Force and Interstate Advisory Committee approval, were as follows: (1) That a decision on the construction of Seneca dam and reservoir on the Potomac main stem be indefinitely deferred, but that the site be preserved as much as possible against further encroachment, in case it is ever needed; (2) That three relatively small reservoirs be built on tributary creeks in the Paw Paw Bends area of the upper Basin, in addition to the authorized Bloomington reservoir on the North Branch, to begin providing a safe margin of water for metropolitan Washington and to serve Basin recreational needs; (3) That a permanent "green sheath" of protection for the Potomac main stem, together with major recreational opportunity, be assured by means of a new kind of composite park of varying width along both shores from Washington, D.C., to Cumberland, Maryland; (4) That the Cacapon River and the West Virginia portion of the Shenandoah be given Wild River status by Congress to protect their shores against excessive and inappropriate encroachment; (5) That water quality programs and research be accelerated toward certain minimum goals; (6) That Soil Conservation Service and related Forest Service programs for erosion control, water management and development, and recreation benefits be accelerated;
