The "goodness of fit" coefficient, r~, is greater than 0.84 for all reservoirs, and greater <br />than 0.90 for most reservoirs for both the Previous CRDSS and the Enhanced analysis. Figures <br />8 through 11 shown time-series plots for each of the four reservoirs highlighted in the CRDSS <br />calibration. As shown, with the exception of Stagecoach Reservoir, both Previous CRDSS and <br />Enhanced analysis predict end-of--month contents very close to measured. In both simulations, <br />predicted end-of--month contents for Stagecoach Reservoir is less than measured, although the <br />seasonal trends are good. The demand on the reservoir is being met, however, the simulated <br />inflow is less than historic inflow. In addition, the Historic modeling approach, which includes <br />an operating rule that releases to meet targets, tends to include a good reservoir calibration even <br />if reservoir water use is not well understood. <br />VariableEff Taskl-5 10 of 17 November 5, 2001 <br />
