Truncating these graphs was done for presentation purposes, to allow better resolution of the most intense periods of rainfall that would have contributed to the damaging portion of the storm and flooding. It should be noted that Figures 20 through 23 presenting information on both no- breach and breach modeling and hydrographs are truncated with respect to timing of the storm as modeled. As is described above, the rain event occurred from Sept 8th and continued until Sept 18th and the HEC -HMS modeling was performed for that entire period. Table 10 shows the modeled peak discharge from each of the six (6) subbasins delineated for rainfall and runoff analysis. For simplicity, the Meadow Basin discharges, including those into each dam and reservoir were combined to their common outflow location at Meadow Dam. Also included in Table 10 is the percent contribution of each of the basins to the total flow seen at the downstream end of the model at the X Bar 7 Ranch calibration cross - section.
