I have a polygon layer of watershed boundaries
And a single multipart feature that contains all public lands for the state.
I need to find the area of public lands within each watershed and add it as a field to each of the watershed polygons.
For example, for the Black river, I just want the area of public lands (tan) that is contained within the polygon.
I assumed I would use a spatial join from this, but I can't figure out how to get the area within each watershed as opposed to the area of the giant multipart public land feature.
