<br /> <br />Water Supply Assumptions <br /> <br />For 1992 operations, three reservoir inflow scenarios were developed and analyzed; <br /> <br />statistically these are approximately the upper decile, mean, and lower decile <br /> <br />inflows and have been respectively labeled the probable maximum, most probable, <br /> <br />and minimum probable (see attached graphs of reservoir parameters). Each <br /> <br />scenario was adjusted for current basin conditions; therefore, the magnitude of the <br /> <br />three scenarios does not necessarily match the historical upper decile, mean, and <br /> <br />lower decile inflows, respectively, The National Weather Services's computer <br /> <br />model, known as the Extended Streamflow Prediction model (ESP), uses current <br /> <br />basin conditions as well as historical data to predict a range of possible future <br />
