Does anyone have any specific guidance on incorporating NHD area data into a delineation?

Question asked by traggatmot on May 5, 2015



I am working on delineating several watersheds for lakes - and of course the delineations are not perfect.  I am new to the Arc hydro tool, so I am learning about the different Sink related tools that might solve this problem.  I keep getting errors using the Create Sink Structures tool, and am trying to figure out why that is occurring....but at the same time / in general, I was wondering if anyone had any experience using the NHD Area data set as a means of identifying "sinks" or adding these data sets to either use an edge of as the pour point or using the footprints as a known sink area.
