Buying Land in Day County, South Dakota

Real, currently-maintained zoning

Day County's Planning & Zoning Office, led by Administrator Dari Schlotte and based in Webster, administers a countywide zoning ordinance. Unlike a meaningful share of rural South Dakota counties covered on this site's state hub, which have never adopted zoning at all, Day County has a real ordinance in place -- and it's not dormant: a set of proposed revisions was circulated in draft form as recently as March 2026, indicating the county actively revisits its code rather than leaving it untouched for decades. Day County also contains eight incorporated municipalities (Andover, Bristol, Butler, Grenville, Pierpont, Roslyn, Waubay, and Webster), each of which may separately handle land-use matters inside its own city limits. Confirm the current, adopted version of the ordinance -- not a circulating draft -- and the applicable district for a specific parcel directly with the Planning & Zoning Office.

Glacial lakes country, and a real federal easement overlay

Day County sits within the Coteau des Prairies, a plateau built from repeated glaciation, and it's studded with small lakes and wetlands as a result -- a landscape distinct from the flatter cropland of much of the rest of eastern South Dakota. Two of its lakes are substantial: Bitter Lake covers more than 15,000 acres and is managed as a walleye and yellow perch fishery, and Waubay Lake covers roughly 15,540 acres, both important recreational and wildlife resources for the county.

That same wet, pothole-dotted landscape is why Day County sits inside the Waubay Wetland Management District, a U.S. Fish & Wildlife Service district (headquartered near Waubay) that manages more than 300 Waterfowl Production Areas -- federally owned wildlife habitat parcels ranging from 40 to over 1,600 acres, totaling roughly 40,000 acres across six northeastern South Dakota counties, including the very first WPA in the district, McCarlson WPA, purchased in Day County in 1959. Beyond outright federal ownership of WPAs, the district also holds thousands of separate conservation easements on privately owned land: a wetland easement (funded largely by federal Duck Stamp sales) permanently bars draining, filling, leveling, or burning a protected wetland basin, while a grassland easement permanently requires the land stay in grass or other permanent cover. In both cases, the landowner keeps title and can typically still farm, graze, or hay the land around (and, if a wetland dries up naturally, sometimes within) the easement area -- but the easement itself is recorded at the county Register of Deeds and binds all future owners, not just the one who sold it.

This matters concretely for a buyer: a parcel that looks like ordinary cropland or pasture may carry a recorded federal easement that limits what you can do with a low spot or grassy area on it, regardless of what the county's zoning ordinance otherwise allows. In mid-2026 the Fish and Wildlife Service also opened a review of how it sets drain-tile setback distances near these protected wetlands, a live rulemaking covered in depth on the conservation-easements page linked below. Given how common these easements are in this part of the state, a full title search and a direct check with the Waubay Wetland Management District office are worth doing before assuming a parcel's drainage or tiling potential.
