If this body of recommendations is significantly implemented as an initial program, it can lead to a good solid beginning on the things that need to be done in the Potomac Basin. Without treading heavily on the freedom of choice of future populations, it can satisfy the water demands of the Basin during a long enough span of years to give scientists time to examine the full range of evolving alternatives for water management, and planners freedom to choose perhaps better ways of meeting future demands than are now available. The program can clean up the main streams of the Basin and assure their healthy and copious flow even in time of drought, keep their banks beautiful, and make them more available than they presently are for the people's enjoyment. Even in the major trouble spots of the present time--stretches like the lower North Branch and the metropolitan estuary--dramatic improvement in the appearance of the water and its usefulness for boating and fishing and such things will be possible if the recommendations are followed out to where they lead, though full restoration in such spots, particularly in the estuary, is going to require an expansion of present knowledge and a long-continuing effort on the part of all agencies and jurisdictions. The program will not assure general protection of the Basin's landscape, for only the Basin's people, generation on generation of them, can assure that. But it can preserve some of the major treasures in that landscape and mitigate some of the worst threats to it. And by fostering projects to illustrate how a respect for the landscape can be put to work, and bringing people into closer contact with the old realities of the Basin's natural world, it can stimulate understanding and feeling that will lead to wider restoration and protection, possibly that general protection that only the people can assure. If the spirit of these recommendations prevails, we believe that they can lead reasonably soon to a Potomac Basin fit to serve as a model for the nation. And if they are followed by further stages of continuing, flexible, coordinated planning that will apply the best technology to new problems as they arise, keep Basin aims in mind, maintain a high sense of values, and leave open all possible options for the people who come after, the Basin will remain a model. And that has been the aiming point of our study and our planning. [Illustration] [Illustration] THE NATION'S RIVER--AN ACTION PLAN I.
