The volume contains summary results of MAGIC calibrations for the DDRP catchments. The summaries are presented for individual catchments within the northeastern and southeastern regions. A separate volume contains regional analyses of the results across all catchments in the northeastern and southeastern regions. The summaries are given for all catchments in each region for which successful calibrations of MAGIC were obtained. The catchment data are drawn from the results files forwarded to Corvallis. The calibration protocol for MAGIC applied to the DDRP catchments involved multiple calibrations for each catchment. Ten calibrations were attempted for each catchment. A catchment was not considered calibrated until at least three calibrations were successful. The multiple calibrations were performed in order to estimate the uncertainty in the calibrated model for each catchment. The procedure is described in detail in another volume. Because multiple calibrations are available for each catchment, the results summarized here for simulated values (or changes in simulated values) are the median (MED) values of all calibrations for an individual catchment. The uncertainies in simulated values (or changes in simulated values) are presented as the difference in the maximum and minimum (MX-MN) values resulting from the multiple calibrations.
