A discrepancy in water surface elevations is expected upstream of this area due to the missing data. The recreated model attempts to approximate the missing data as much as possible. The existing conditions model should be relied upon to predict water surface elevations. Existing Difference (O-R) Difference (O-E) Original Recreated Existing Difference (O-R) Difference (O-E) 5
