If you google:Mott,ND pheasant hunting, you'll find a City of Mott site. They appear to offer plat maps from some of their local stores.
I doubt if the State of SD has this kind of map, with this level of detail. When I was hunting Faulk county, (SD). I checked with the county seat and they gave me a map book of the county - very helpful!
If you can't locate the "city site" I suggest you call the city clerk, Hettinger County, for info on maps.
