ll others because of a feeling at higher
levels that certain recommendations could be better evaluated in terms
of a final report's whole set of proposals. In the present set of
recommendations they are repeated, for they represent genuine needs.
Some have been slightly altered in the light of evolving restrictive
reality, more recent knowledge, or flexibility, and the suggested or
implied Interim scheduling for some has been changed. It is no longer
envisioned, for instance, that the parkway extension below Mount Vernon
will be authorized and constructed quickly.

The present recommendations, though much wider in overall scope than our
earlier ones, represent only a first step in planning for the Basin, for
reasons presented in full in this report. They are attuned to present
economic and technological possibilities, as they must be. We believe
that if they get full and calm appraisal they will prove to be
acceptable politically, for all of them that call for major projects
represent solutions for acute and imminent problems for which other
satisfactory solutions do not presently exist, and to the greatest
possible degree they have been made flexible to accommodate possible
future change in aims or techniques.

In most cases, the reasons for specific recommendations have already
been given in the body of this report. However, the primary public
interest that focuses on the matter of major storage reservoirs may make
it worthwhile at this point to review and enlarge upon the facts. Some
reservoirs are going to have to be built if the Basin is to cope
satisfactorily with water supply, water quality, and recreational
demands. At the time of the _Interim Report_, we recognized that the
three reservoirs in the Paw Paw Bends area, together with Bloomington,
were very possibly not going to be enough to meet the need, but we made
a recommendation for their authorization because it was clear that they
would take the edge off the immediately looming water problem at
Washington, would mesh well with any additional future storage in the
Basin, and would have no major disruptive scenic effects but instead
would provide a great deal of high-quality flat-water recreation in an
area where there was significant demand for it.

These considerations still apply. However, the more complete picture of
Basin water problems that has emerged in our studies since the _Interim
Report_ shows that at least two more reservoirs are very possibly
