The given reservoir point is positioned too close to an impounding structure and falls within that structure's footprint. DSS-WISE Web has the ability to attempt to reposition the reservoir point by moving it away from all impounding structures within the reservoir, but this procedure has failed to provide an adequate solution. The width or footprint area of an impounding structure is dependent on its hydraulic height and structure type(s). Ensure that you have given the correct values for these parameters and have positioned the reservoir point properly.
