The project <br /> <br />will provide an average of 25,400 acre-feet annually <br /> <br />to create a year-round live stream below McPhee <br /> <br />dam. Releases of 78 second-feet during wet years, <br /> <br />50 second-feet during normal years, and 20 second- <br /> <br />. <br />feet during dry years will be made. <br /> <br />(3) Salinity Increases <br /> <br />^ salinity standard of 879 mg/l at Imperial Darn <br /> <br />was proposed by the seven Colorado River Basin states <br /> <br />and approved by the Environmental Protection Agency <br /> <br />in 1976, Establishment of this standard was part <br /> <br />of the basinwide salinity program in the Colorado <br /> <br />River Basin which is being undertaken with the <br /> <br />general objective of keeping salinity in the Lower <br /> <br />Basin at or below present levels while the Basin <br /> <br />states continue to develop their 'compact appor~ <br /> <br />tioned waters. Public Law 93-320, the Colorado River <br /> <br />Basin Salinity Control Act, passed June 24, 1974, <br /> <br />authorized construction of four salinity control <br /> <br />units and study of additional units, Installation of <br /> <br />all these units would reduce the concentration at <br /> <br />Imperial Dam by an estimated 171 mg/l by the year 2000. <br /> <br />Conservation measures, including those related to <br /> <br />water quality, are required by provisions of the <br /> <br />repayment contract for the project, <br />
