The committee will document <br />a coordinated approach to salinity control as well as keeping the general <br />public advised of salinity activities so that each participant will have <br />a clear understanding of what is needed and who will perform the work. <br />The individual committee members shall keep their parent organization <br />advised of the activities and functions of this committee." <br /> <br />C'. " <br />-' <br /> <br />As pointed out earlier, the local irrigation and d:rainage organizations <br />were here and operating long before the problem appeared and it is the <br />common goal of these organizations to help guide the salinity control <br />program through to a beneficial conclusion, that will result in future <br />operations and conditions that are in the best interest of the valley's <br />water users at all times. <br /> <br />NOTE: <br /> <br />The above language enclosed in quotation marks is taken from a <br />statement dated December 21, 1972, that was drawn np at the time the <br />Grand Valley Salinity Coordinating Committee was formed, <br /> <br />The Bureau of Reclamation <br /> <br />The Bureau of Reclamation is serving as the coordinating agency for <br />the Grand Valley Improvement Project. The Agricultural Research Service, <br />Colorado State University, and the water users of the Grand Valley are <br />currently working on problems associated with the project. Their findings <br />are collected and combined by the Bureau. <br /> <br />A canal and lateral inventory of the valley has been recently <br />completed, and a topographic analysis of the valley is being prepared <br />through contracted aerial photography. From these studies, the Bureau <br />hopes to identify problems and advantages of existing irrigation structures <br />and to arrive at appropriate designs and cost estimates for improvement <br />of the Grand Valley irrigation systems. <br /> <br />Irrigation Management Services is a program designed to use irrigation <br />water at maximum efficiency to reduce amounts of water needed as well as <br />to lessen deep percolation and, hence, salt loading in the Colorado River. <br />IMS has just completed its forth year of operation, and figures collected <br />to date generally indicate that it has successfully increased the crop <br />yields where it has been implemented. During the non-irrigation season, <br />analysis will continue on data available from this year's operation to <br />identify possible improvements for next year. The Bureau of Reclamation <br />is currently training personnel of the Grand Valley Canal Systems, Inc. in <br />order to facilitate a change-over from government control to private oper- <br />ation of the IMS program. <br /> <br />Water Systems Improvement 1S the major plan of the Bureau of Reclamation <br />for easing of the salinity problem. Concrete lining of canals and laterals <br />and replacement of worn-out or outdated structures would eliminate water <br />seepage and end the contribution of canals and laterals to the high ground <br />water table in the Grand Valley.
