Figures 6, 7, 8, 10, 13, 14, 15, 16, were modified to reflect minor changes in simulated water-surface elevations, streamflows, simulated temperature profiles, and residence times at selected locations as a result of three corrections to the segment sequence in the model geometry.

Text was modified. Number of days was changed on page 1 ("Abstract" section) to reflect a minor change in the range of residence times as a result of the geometry corrections. Two instances of mean absolute error and one instance of root mean square error were changed on page 12 ("Hydrodynamic Model Calibration" section) to reflect minor changes in the model calibration metrics at selected locations as a result of the corrected geometry. Four instances of root mean square error, one instance of mean absolute error, three instances of calibration results, four instances of mean difference, two instances of streamflow difference, one instance of average difference, one instance of average velocity difference, two instances of channel area difference were changed on page 16 ("Hydrodynamic Model Calibration," "Streamflow," "Velocities," and "Wetted Channel Area" section) to reflect minor changes in simulated streamflow characteristics at selected streamflow measurement comparison locations. One instance of mean absolute error and root mean square error and three instances of temperature increases were changed on page 19 ("Water-Temperature Calibration" section) to reflect minor changes in calibration metrics at selected locations resulting from the corrections in model geometry. Three instances of residence time were changed on page 24 ("Resident Times" section) to reflect minor changes in calculated residence times as a result of the corrections in model geometry. Three instances of water temperature and one instance of residence time were changed on page 33 ("Summary" section) to reflect minor changes in summary statistics associated with sensitivity analyses and simulated residence times as a result of the three corrections in model geometry. 

Tables 3, 4, 5, 6, 8, were modified to change data to reflect minor changes in calibration and validation metrics of water-surface elevations and streamflow characteristics and minor changes in sensitivity analysis resulting from three corrections to the segment sequence in model geometry.
