Merge polygons in watershed

AlexiaReyes

I made a watershed using spatial analysis/hydrology tools. Now, I need to merge the polygons that make up the watershed to make one large polygon. When I try to select the polygons I want to merge, the merge feature under the editor tab is grayed out. It does not allow me to use the data management/ merge tool either. Not sure how to work around this

If you have used Watershed (Spatial Analyst) tool, its output is a Raster. Please ensure you use a Raster to Polygon (Conversion) tool to convert it to polygon feature class first.

Then you may use Merge under Edit tab, or Dissolve (Data Management) Geoprocessing tool.
