Chambersburg lies in an area where opposition to any major reservoirs has been heavy. An interim solution to the local problem, though possibly not satisfactory in the long run, can be found in a system of small headwater reservoirs. The major Chambersburg reservoir site has received full consideration as an element in a water-storage package to begin dealing with Basin demands. But its immediate advantages are not so unique as to justify going against the area's apparent wishes, and it has not been included as a recommendation. The reservoirs at Verona near Staunton and at Sixes Bridge on the Monocacy, fortunately, can be adequately coordinated with Bloomington and the three Paw Paw impoundments to provide roughly a twenty-year margin of safety in water supply at Washington, besides coping with foreseeable shortages in their immediate neighborhoods, furnishing desired flat-water recreation, and contributing greatly to water quality and recreation benefits downstream. They are also locally and State supported. For these reasons, they have been chosen to fill out the recommended system of major reservoirs to meet near-future Basin demands. The construction schedule recommended is based on the rate at which upstream and metropolitan demands are expected to develop in relation to each other. And, in accordance with flexible principles of planning, there is provision that if more desirable alternative sources of water or any changes in expected aims or demands evolve, the schedule or the plan itself may be altered. Thus, if this first-stage plan is adopted, the reservoirs to which the region will be committed at any given time will be only those for which there is actual immediate need, but coordination will not have been lost. This same kind of flexibility is built into the recommendations relating to flow augmentation for quality control. Other proposals for major action are self-explanatory or are analyzed in detail in separate sub-task force material. Among these latter is the Potomac National River, as the park proposal is now designated, which represents the most hopeful approach to defending the main stem Potomac against destructive encroachment and enhancing its potential for recreation. Some of the recommendations presented are relatively small in scope but nonetheless essential to cleaning up, preservation, or other desirable ends. Others aim not toward immediate action but toward research or legislation to clear the way for needed action--examples are those regarding acid mine drainage and the possible need for a new Federal category of "pastoral" or "scenic" rivers in populated regions. And still others are only suggestions that non-Federal jurisdictions act in regard to specific problems that fall within the realm of their responsibility. [Illustration]
