The study provided the information and perspectives required to decide whether the Tocks Island Lake project should proceed or be deauthorized. Major elements analyzed included eutrophication, growth management, salinity intrusion, legal bases of flow allocations, and the formulation of practical alternative programs. Major findings were that: significant needs must be met by water resources of the Delaware River Basin in the areas of water supply, flood control, recreation and electric power; technically viable alternatives to Tocks Island project do exist, although relative costs, benefits, impacts and the degree to which each satisfies area needs vary widely; and the multipurpose nature and large scale of the Tocks Project could make it more cost effective than alternatives but the combination and concentration of purposes would produce adverse impacts on transportation, other public facilities and services, land uses and the environment in portions of the region.
