Using watershed for breaklines...what about inverted watershed

Hi, I've been working out in the desert modelling large sites for solar projects. In the effort to accurately generate landxml surfaces that are smaller in size I've found that the watershed lines are exceptionally valuable at capturing the subtle edges of the surface. Is there a workflow that could be used to capture the invert of the watershed?

    You can scale your elevation layer to -1 and you will have the "inverted" terrain model. Than perform again the watershed.
