Show THE ALL-AMERICAN" CANAL. 73 PRELIMINARY REPORT. (a) On Decerrmer 7, 1918, a preliminary report was made to the board of engineers in order to furnish certain information to the Imperial Irrigation District. (b) The board of directors of the Imperial Irrigation District entered into a contract with the Secretary of the Interior on October 23, 1918, for a connection with Laguna Dam and for the construction of an all-American canal upon the line located and approved as provided hj the terms of the cooperative contract of February 16, 1918. Under the terms of the above-named contract of October 23, 1918, it was necessary to submit the contract to a vote of the irrigation district for their ratification within six months from the date of signing. The directors of the Imperial Irrigation District, wishing to submit the contract to a vote at an early date, requested that a preliminary report be made in order that they might be able to place all the information possible before the people of the irrigation district. (c) The present report is to a large extent a repetition of the preliminary report, with some slight modifications in the estimates of cost and some additions. EARLIER SURVEYS. (a) Several surveys and estimates have heretofore been made for the purpose of diverting water at Laguna Dam into the Imperial VaEey and onto the mesa lands by what has been termed a high-line canal. These surveys followed along the route and contemplated the enlargement of the present Yuma main canal from Laguna Dam to siphon drop, and thence along the base of the hills bordering the valley from this latter point to the Southern Pacific main-line track. From this point the surveys followed the right bank of the Colorado River, generally parallel therewith and but a short distance from the river bank, to a point near the international boundary line. From this latter point the plans followed by the several surveys have differed to some extent and are described below in more detail. (6) In 1903 and 1904 the United States Geological Survey made a topographic survey of the Yuma project on the California side of the river, extending the topography to the international boundary, and thence westerly for about 2 miles, covering a strip along and parallel with the boundary and about 500 feet in width. (c) In 1908 the Reclamation Service made a topographic survey of the greater portion of the mesa east of the present Imperial east high-line canal as far north as the Southern Pacific Railroad. At this time some preliminary lines were run for a high-line canal south of the sand hills through Mexican territory. (d) In 1913 the Imperial Irrigation District made a preliminary survey for an all-American aqueduct of a capacity of about 3,667 |
