*Note: A value of 6,000 ft3/s indicates a required flow of less than or equal to 6,000
ft3/s. Many sites had stage requirements well below the calibrated range of the
hydraulic model.
Using stage-discharge rating curves generated by
elevations corresponding to the minimum dis-
charge value of 6,000 ft3/s employed in HEC-2.
HEC-2 at each site, it was possible to turn the
critical shut-off stages for an intake into a required
Extrapolation to these very low stages would be

unreliable and is unnecessary for the purposes of
