The purpose of this report is to present additional conclusions of the Departpient of the Interior's review of the International Joint Commission's report on the international Passamaquoddy tidal power project, April 1961. It suppplements the report of July 1963 entitled "The International Passamaquoddy Tidal Power Project and Upper St. John River Hydroelectric Power Development.”

The report embraces the considerations and suggestions of the Joint ArmyInterior Advisory Board, which was created shortly after President Kennedy's acceptance of the Department's report on July 16, 1963. This Board consists of representatives from the Corps of Engineers, the Department of the Interior, the Department of Commerce, and the Federal Power Commission as participating members, with representatives of the Bureau of the Budget, the President's Office of Science and Technology, the President's Council of Economic Advisers, and the Atomic Energy Commission as observers.

The suggestions of all representatives on the Board were considered, but since the Board's function was advisory, the views of the individuals might not necessarily fully conform with the agencies' position in commenting on the report. The following contributions by the Corps of Engineers are included:

(a) Geologic investigations and field explorations at the sites of all structural components.

() Field surveys.
(C) Hydrologic investigations of the St. John River.

(d) Layout and design of facilities for powerplants at Passamaquoddy; power dam and closure dikes at Dickey; and reregulating and power dam at Lincoln School.

(e) Studies of use of inclined axis turbines at Passamaquoddy in cooperation with the Bureau of Reclamation.

(f) Planning appraisal of all lands and damages for the entire project.

(9) Cost estimates of facilities. The Department of Interior in its traditional role for water resource development accepts the basic responsibility for this report which portrays a feasible and workable plan for utilization of this unique water power resource—the tides. The Department conducted the economic analysis and marketing studies and provided the cost estimates for the transmission facilities. The Department of State is working toward an agreement with the Canadian Government. A technical briefing session was held in Ottawa, Canada, December +5, 143, as well as other meetings between officials of the two countries.

CHAPTER II. SUMMARY-FINDINGS The results accomplished since completion of the July 1, 1963, report confirm the engineering and economic feasibility and the desirability of constructing, by the l'nited States, the proposed international Passamaquoddy tidal power project, the Dicker storage reservoir and powerplant, and the Lincoln School reregulating reservoir and powerplant on the upper St. John River and the associated transmission system. These include firm geologic data and more detailed economic analyses than previously applied as well as updated cost estimates.

The proposed project offers a practical plan for harnessing, for the first time in the history of this Nation, the energy of the tides for the economic benefit of a Large section of the country. The coupling of this resource with development of the hydroelectric power potential of the upper St. John River provides a multipurpose project with very significant electric power, flood control, recreation, and
