<br />os::. <br /><::> <br />...:I <br />00 <br /> <br /> <br />the Forum provides for the control of about 1,476,600 tons of salt load reduction annually by the <br />year 2015. .. <br /> <br />Should more water development projects be completed than are projected to occur before <br />control measures are identified or brought on line, temporary increases above the numeric criteria <br />could result. However, these increases will be d~med in conformance with the standards if <br />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 <br />that when river flows return to normal and satisfactory reservoir conditions prevail, concentrations <br />will 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 />in the year 2015 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 main stem 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- <br />share with federal appropriations, and Basin irrigators stand ready with cost-share dollars to install <br />salinity reducing measures. <br /> <br />viii <br />
