Reference: Your despatch No. X-497 of March 10, 1952.
The House Foreign Affairs Committee yesterday requested the State Department, in a letter addressed to Dulles, to act in ending the 1940 executive agreement with Canada that authorized diversions of the Long Lac and Ogoki Rivers from Hudson Bay into Lake Superior. Ostertag, who originated the June 25, 1952, reference to the IJC in this matter, contended that the IJC should be given jurisdiction over the flow of the two rivers.
2. Patterson and Hattaway of the Engineering Board on levels of Lake Ontario were scheduled to appear before the IJC later on during additional hearings. Brown and Vallance of the State Department told us today that the committee's letter has not yet reached their level but Vallance thinks, however, from what he has read about the letter, the State Department may have to take action at once before additional hearings are held by the IJC.
