Hi, I delineated subwatersheds and there are areas of land that were not delineated, I'm guessing due to the lack of drainage lines/drainage points in those areas. Is there anyway to create subwatershed polygons in the areas where no subwatersheds were created? I have a polygon outlining the watershed, along with the subwatersheds that were delineated. Is there a tool where I could these two layers to say "create a polygon where one wasn't created within the larger polygon"? Thanks in advance. Angel

I'm trying to run depression evaluation on a "prefill DEM" (file created by sink prescreening) and I'm getting the warning message "Build VAT may have failed. Make sure that raster target location is not GDB and the path does not contain space!" The size of the prefill DEM is 8.86 GB. Is it possible that I'm getting this message because the DEM is too large, because the raster target location is fine. Any help would be appreciated. Angel

Hi, I trying to delineate subwatersheds using Arc Hydro. I'm using a DEM derived from LIDAR. So far, I've converted the DEM to an integer DEM and run the sink evaluation. The size of the prefilled DEM that I'm trying to run the depression evaluation on is 8.86 GB. My problem is when I run the depression evaluation, it runs for a while (over 8 hrs) then gives me the message "Build VAT might have failed make sure raster target location is not GDB and path does not contain space." Does this simply just mean I have to change the path of where it stores the depression data? Would I do this under "Set target locations for HydroConfig, Layers?" I looked back at some other depression evaluations and their all located in the geodatabase in layers so I'm not sure what the issue is. Is the DEM too big? Any input would be appreciated. Thanks.
