7 INTRODUCTION HARRY E . S CH WARZ Clark University Water supply is an essential service that requires professional water managers to plan continuously and carefully as system expansion is costly and time-consuming.

In 1972, the North Atlantic Regional Water Resources Study (NAR) found that water-quality maintenance and water supply for public, industrial, and powerplant cooling purposes were the most important waterresource problems of the northeastern United States (NAS, 1972a)

The two latter rivers are almost fully developed, and the Potomac can, in its present unregulated stage, barely supply present summer peak demands. Plans for the future foresee a ~3 mixture of regulation of the Potomac, local reservoirs, interconnections of water-supply systems, emergency restrictions, use of water-saving devices in new construction, and reuse of water from the Potomac estuary and advanced waste-treatment plants (Northeastern United States Water Supply Study, 1975~.

Other communities in the area resorted to emergency restrictions, some of quite stringent nature. Ongoing planning includes additional diversion of water from the Connecticut Basin and the Merrimack Basin, either through high-flow skimming or reservoir development, as well as through new reservoirs in the other aforementioned streams in the area and groundwater development (Northeastern United States Water Supply Study, 1975~.

A decrease in the mean annual yield would be in his opinion most detrimental to Boston's water supply. Increased persistency, longer periods of less flow, would be the next most damaging manifestation of climatic change.

Work toward this end has been initiated by the author in cooperation with lames Wallis and others. CONCLUSION What does all this mean to those who must plan and manage the water supply of the northeastern United States?

Beyond these preliminary results, it is appropriate to speculate on the changes in water-supply planning and decision-making occasioned by findings that significant climatic change is at hand or that such changes are of no consequence. In the latter case, unwarranted considerations should not be allowed to complicate and delay water supply plans and their implementation.
