A streamflow forecast procedure for the Missouri River Basin, to meet the needs of the Corps of Army Engineers Division office at Omaha, Nebraska is described in detail. Snow survey and precipitation data were analyzed by automatic data processing system (ADPS). Problems encountered during the electronic computer developing the multiple regression equations are discussed, primarily the coding and decoding and negative values of multiple correlation coefficients. Tests were made for minimizing the effect of 'local Anomaly' and negative values are described. A system of dividing the Missouri Basin into snowmelt basins from predominantly rainfall basins proved satisfactory values for coefficients. The resulting scheme provided results well within the 20% limits.
