WebThe first step opens the Flow Direction tool. By determining the flow direction for the area, you'll be able to identify sinks, which are areas where water can no longer flow. For Input surface raster, choose Stowe_DEM. For Output flow direction raster, click the text box and confirm that the output location is the Stowe_Hydrology geodatabase.
