This category appears at the selection of any regulation discharge method in the Regulation Discharge category, so is related to the operating level balancing approach to flood control. This category allows the user to specify that upstream reservoirs are permitted to cause flooding with hydropower releases at this control point.

This default method for the category means no hydropower flooding exception is specified.

This method specifies that flooding at the given control point will not constrain hydropower releases. This method is checked within execution of the HydropowerRelease predefined function (see HydropowerRelease in RiverWare Policy Language (RPL)). If this method is selected, the computational subbasin will skip this control point when it is checking for additional downstream flooding at control points.
