The components used in computing the <br />index are reservoir storage, snovpack water equivalent, and precipitation. <br />The SWSI number for each basin ranges from a -4.00 (prospective water <br />supplies extremely poor) to a +4.00 (prospective water supplies plentiful). <br />The SWSI number is only a general indicator of surface water supply condi- <br />tions. Further data analyses aay be required in specific situations to more <br />fully understand the impacts of abnormally dry or vet conditions susgested <br />by the SIlSI. Development of. the SVSI bas been a cooperative effort between <br />the Colorado State Engineers' Office and the Soil Conservation Service. <br />
