Economic consideration of water yield forecasting for the Salt River Valley, Arizona

Snowmelt water provides the major portion of the annual runoff to the Salt River Project System. The worth of this runoff, equated to the basic snow survey data and resulting water yield forecast, is discussed in terms of some economic considerations. These considerations are emphasized from the standpoint of the application by a water user of such forecast information.In discussion Mr. Jesse D. Ellis describes his application of Mr. Moore's economic theories to the savings possible in power development by having advance knowledge of a possible 10 percent plus or minus average potential runoff into reservoirs by forecasting.
