@radeknovotny94 Please note that r.watershed doesn't require modified DEM as input. It could be even probably counter-productive. There is also probably better candidate r.hydrodem. This issue should be discussed on GRASS User ML to clarify things. See also related wiki page, https://grasswiki.osgeo.org/wiki/Hydrological_Sciences#Sink_filling:_why_not_needed_in_GRASS_GIS
