It is estimated that up to <br /> <br />2 million acre-feet of new water could be added to the river system. <br /> <br />This would serve to Significantly improve the salinity levels. <br /> <br />Desalting will initially involve the installation of a research and <br /> <br />development prototype faCility using the reverse osmosis process. The <br /> <br />prototype plant would have a capacity of IS mgd and could be expanded <br /> <br />to 150 mgd. The facility would be located in the lower reach of the <br /> <br />river. If expanded to a capacity of about ISO mgd, the salinity levels <br /> <br />in the lower reach would be greatly improved. This would be a Coopera_ <br /> <br />tive effort between the Office of Saline Water and the Bureau of <br /> <br />Reclamation. <br /> <br />Geothermal investigations are now being conducted by the Bureau of <br /> <br />Reclamation and the Office of Saline Water. These investigations <br /> <br />could Ultimately lead to additional sources of water. This water <br /> <br />could be fitted into the overall river basin management plan to achieve <br /> <br />further improvements in Water quality. <br /> <br /> <br />Research is underway or scheduled which would provide valuable inputs <br /> <br />to the salinity control effort. Included is such work as developing <br /> <br />better predictions of irrigation return flow quality. deriving the <br /> <br />systems for assessing ecologic impacts of water reSOurce projects. <br /> <br />xiii <br /> <br />
