2 Floodway data in parenthesis ( ) represent floodway based on 0.5 ft rise in Energy Grade Line (EGL)- all other floodway data pertains to encroachment
for 1 foot rise in EGL- widths relative to channel centerline looking downstream.
* Width does not include shallow flooding area(s) between limits of Dry Creek No. 2 Ditch split flow.
** Distance measured to split flow boundary.
# Discharge and corresponding floodplain/floodway data represents estimated flow in main channel cross section - see separate floodplain/floodway data
