The Soil Conservation Service (SCS) Snow Survey Program makes periodic seasonal streamflow forecasts at over 500 major points in the western states. These forecasts are the basis for making rational, objective agricultural water management decisions from year to year. Seasonal crop water demands must be balanced against expected supply. An automated procedure is presented called SWAP that links seasonal streamflow forecasts (water supply) to local irrigation water demands using SCS field irrigation application expertise and the agency's planning and technical assistance delivery system.
