Day County, SD
Conservation Easements in Day County, South Dakota
Day County's hub flags a 2026 federal rulemaking on drain-tile setbacks near protected wetlands as unresolved. Here's the fuller picture: what the Fish and Wildlife Service was actually reconsidering, the lawsuits already underway before the 2026 comment period opened, the unusually large public response it drew, and what applies to a Day County easement holder right now while the outcome remains undecided.
This page covers what's specific to Day County. For the general explanation, see the national guide.
The 2026 review targets a 2023/2024 rule that itself formalized decades of practice
The rule under review in 2026 wasn't a brand-new restriction -- it was a 2023 rule, further codified in 2024, that formalized a drain-tile setback practice the Fish and Wildlife Service says it had already followed for roughly 60 years on land carrying a federal wetland easement. Under that rule, a landowner who wants to install drain tile near a protected wetland basin requests a setback distance from the Service, calculated using site-specific factors -- soil characteristics, tile diameter, depth below the surface, and topography -- rather than a single fixed number applied everywhere. A landowner who fully complies with the Service-calculated setback, and doesn't later modify or replace the tile, receives a safe-harbor protection from legal action even if the compliant tile later happens to drain part of the protected wetland anyway.
That rule was already facing legal challenges before the 2026 review began: Ellingson Drainage, a firm serving Prairie Pothole-region farmers, sued over the 2024 rule, but a federal court dismissed that case in 2025 for lack of standing, and separately, in April 2025, a North Dakota farmer represented by the Pacific Legal Foundation filed suit against the Fish and Wildlife Service challenging the underlying easement/setback framework. On July 24, 2026, in that legal and political context, FWS published a Federal Register notice requesting public information on its process for calculating drain-tile setbacks -- not a formal proposed rule change yet, but a request for input widely read as a step toward loosening the existing setback methodology.
A comment period that drew an unusually large, lopsided response
Comments closed August 7, 2026, and the response was large by the standards of this kind of technical rulemaking: more than 219,000 comments were logged at Regulations.gov, with hunting and conservation organizations (including Ducks Unlimited and Delta Waterfowl, according to contemporary reporting) mobilizing members to oppose weakening the setback methodology, alongside some members of Congress and other stakeholders urging the Service to leave the existing rule in place. The volume of opposition doesn't bind the agency's decision -- public comment informs but doesn't legally control a federal rulemaking outcome -- but it does mean the administrative record now underlying any eventual FWS decision is unusually large and heavily weighted toward preserving current protections.
As of this page's research, we found no indication that the Fish and Wildlife Service has issued a final decision, a formal proposed rule, or a public timeline for one following the August 7, 2026 comment close. That means the practical, current answer for a Day County landowner with a recorded wetland easement is: the 2023/2024 setback-request process, with its site-specific calculation and safe-harbor protection for compliant tile, remains the rule in effect today. Don't plan a drain-tile project around an anticipated change that hasn't happened -- request a current setback determination from the Waubay Wetland Management District office using the existing process, and separately ask that office directly whether it has received updated guidance since the August 2026 comment period closed.
