The Adviser on Political Relations ( Duggan ) to the Mexican Ambassador ( Castillo Nájera )

My Dear Mr. Ambassador: I refer to various conversations you have had with representatives of the Department and particularly to your memorandum of March 19, 1942, with respect to the possible allocation of waters of the Colorado River to Mexico under the contemplated Convention concerning international streams.

[Page 558]

As you know, representatives of the Department recently attended a meeting in El Paso of representatives of the seven Colorado River Basin States to explore the possibilities of allocation of Colorado River waters to Mexico. A further meeting between representatives of the Department and of the Basin States will be held in El Paso next week. The Department hopes to be in a position shortly after that meeting to resume discussions with you on this question.

I am, my dear Mr. Ambassador, with kindest personal regards,

Very sincerely yours,

Laurence Duggan
