<br />Co.) <br />CJl <br />00 <br />N <br /> <br />According to the October 1980 Monitoring Plan for <br />Stage I, it is expected that ameasurable decrease in salt <br />load will be observed about one year after implementation <br />of control measures. It may take several years before <br />all effects of Stage I are realized, particularly since the <br />laterals are yet to be started. With the prospect of early <br />completion of Stage I canal lining and successful monitoring <br />results, construction of Stage II should be accelerated. <br />In particular, work should be initiated on design and <br />specifications for those portions of the Stage II area <br />that show considerable promise for salinity reduction. <br /> <br />Analysis <br /> <br />of the results of canal lining in Stage I area <br /> <br />should be expedited to determine if additional canal lining <br /> <br />in the Stage II area is justified and could be undertaken <br /> <br />prior to completion of all planned Stage I construction and <br /> <br />monitoring. Canal consolidation may be very desirable from <br />a cost as well as operating and maintenance perspective. <br /> <br />WPRS should include an evaluation of canal consolidation as <br /> <br />part of the alternatives for salinity control in the Stage <br />II planning effort. <br />Paradox Valley Salinity Control Unit, Colorado - The <br />Paradox Valley Unit like Grand Valley has been under intensive <br />study for nearly 10 years. It, like the other units, has <br />been subject to a number of significant delays in completion. <br />On June 25, 1980, WPRS advised the Council by letter of a <br />potential four-year delay in completion of the Paradox Valley <br /> <br />-3- <br />
