Hello Adam, hope I understood what you mean to do. If I had to cope with your problem, I would import the source file as points, then run v.to.rast, and r.surf.nnbathy with the l interpolation method. The risk for this solution is the triangulation performed by r.surf.nnbathy be different from

IMO the esri term of a filled DEM being hydrologically correct is a misnomer. Natural terrain has real depressions that impact surface water flow. Big depressional wetlands can retain water and release via groundwater or evapotranspiration. I like how r.watershed acomodates known
