SPEAKER: I am transmitting herewith a report dated January 26, 1944, from the Chief of Engineers, United States Army, together with accompanying papers and illustrations, on a preliminary examination and survey of the following streams which form the Merced County Stream Group in the San Joaquin Valley, Calif.: Bear, Black Rascal, and Mariposa Creeks in Merced County; and Canal, Fahrens, Black Rascal, Bear, Miles, Owens, Duck, Mariposa, Little Deadmans, Big Deadmans, and Burns Creeks, Calif. This report is submitted in compliance with an act of Congress approved on May 6, 1936, and the Flood Control Act approved on June 22, 1936. Inasmuch as the proposed project is not essential to the war effort and since there would be large requirements for labor, materials, and equipment, the Department desires that, if the project is approved, initiation of construction work thereon be deferred until after the war. The Bureau of the Budget has been consulted and advises that, while there would be no objection to the presentation of this report to the Congress, the submission, during the present emergency, and in the absence of evidence showing that the proposed works are necessary to the prosecution of the war, of an estimate of appropriation for the construction of the project would not be in accord with the program of the President. Respectfully, HENRY L. STIMSON, Secretary of War. VII |
