<br />'.' <br /> <br />Rostriction of Delta Area - Live Delta <br />This outline has been given to show that, since <br />development commenced, the effect of the construction of <br />the protective levee system has been to restrict very <br />greatly the delta available to the River; first by the <br />Yuma and C. D. levees, then by the Volcano Lake Levee <br />which shut off the Mexicali and Imperial Valleys, and <br />later by the Saiz, Ockerson, Bee River, Pescadero and <br />Rodriquez levees. <br />As a matter of fact, the River could not have been <br />held in such a small restricted area. The elevations and <br />topography of certain parts such as the Volcano Lake area, <br />as well as other factors, were such that under natural <br />flow conditions, the most that would have been possible <br />would have been a limiting of the flood plain to the area <br />lying south of the Volcano Lake Levee and Saiz Levee. <br />Even this represented a rGdu,ction in the area of tho' delta <br /> <br />,.' <br /> <br />- 11 - <br />
