The use of precipitation gage measurements in forecasting the inflow to Lake Mead

With the completion of Boulder Dam and the filling of Lake Mead to maximum capacity, the problem of forecasting the inflow from the Colorado River became evident. Studies have been under way for several years gathering data and analysis work for developing a suitable formula to meet the complex problems involved in operating this huge multi-purpose project. Precipitation gage networks over the main and tributary basins had been intensified, snow survey courses established in the high elevations, evaporation and other pertinent meteorological data measuring stations been established in anticipation of the problem. Trial equations will have to be tested with actual practice to clear the deadwood and introduce new factors before a satisfactory solution is solved.
