indication that the use of average efficiencies during the Previous CRDSS efforts minimized the
effects of uncertainties regarding appropriate maximum efficiencies and return flow locations.
Therefore, additional calibration efforts focusing on basin or sub-basin maximum efficiencies
and return flow locations are recommended.
