<br />o <br />'<1' <br />No <br />C> <br /> <br />Based on the data available, the Forum concludes that the measured salinity will not exceed <br />the numeric criteria during the next three years. The Plan of Implementation adopted herein by the <br />Forum provides for the control of about 1,800,000 tons of salt load reduction annually by the year <br />2020. <br />Should more water development projects be completed than are projected to occur before <br />salinity control measures are identified or brought on line, temporary increases above the numeric <br />criteria could result. However, these increases will be deemed in conformance with the standards <br />if appropriate salinity control measures are included in the plan. <br /> <br />Increases above the criteria as a result of below normal annual river flows and/or low <br />reservoir storage conditions will also be considered in conformance with the standards, provided that <br />when river flows return to normal, and satisfactory reservoir conditions prevail, concentrations will <br />then be at or below the criteria level. <br /> <br />The Forum has reviewed the impact of the program on projected salinities and finds that <br />through the year 2020 the plan will control salinity levels so that, with long-term mean water supply <br />conditions, salinity levels will be below the numeric criteria at the three stations. The salinity <br />standards provide protection from long-term increases in economic damage to downstream users. <br /> <br />Because of the long lead-time required to conduct salinity studies; complete environmental <br />and feasibility reports; implement; and achieve full salinity reduction effects at the lower Colorado <br />River mainstem stations, continued funding is necessary for the recommended Plan of <br />Implementation to proceed as set forth in this Review. Non"federal funds are available to cost-share <br />with federal appropriations, and Basin irrigators stand ready with cost-share dollars to install salinity <br />reducing measures. <br /> <br />viii <br />
