RECIPIENT'S CATALOG NO. <br /> <br />16. ABSTRACT <br />This research report discusses findings from a study designed to <br />develop a method of forecasting economic impacts of salinity of the Colorad <br />River upon various users of Colorado River water in the southwestern United <br />States. One objective was to update, revise, clarify, and refine the esti- <br />mates of economic damages from salinity in the Colorado River that had been <br />described in earlier studies. Another objective was to provide a better <br />means of estimating present and future salinity damages, basically through <br />the development of a comprehensive and user-friendly personal computer <br />program. A final objective addressed unresolved questions and issues about <br />Colorado River salinity, including areas of damage not previously included <br />in estimates. <br />By using one or more selected baseline salinity levels, a potential <br />problem is avoided: that of measuring damages against an idealized water <br />supply that'rarely exists in nature and could never be achieved technologi- <br />cally or ecanomically for most water supplies. Measuring against such a <br />water supply would exaggerate the true damage figure. <br />The total damages from Colorado River salinity range from $310.8 <br />million to $831.1 million annually based on the 1976-85 average level of <br />river salinity and two selected baseline values. <br />17.
