Feds Move to Scrap Wetland Rule Protecting America’s ‘Duck Factory’

The federal government is taking another look at a rule meant to keep agricultural drainage systems from drying wetlands Americans have already paid to protect. On July 24, the U.S. Fish and Wildlife Service opened a 14-day public comment period on its drain tile setback rule for federally protected wetlands in the Prairie Pothole Region. The comment period closes Aug. 7.

The notice asks whether the 2024 rule has worked and how the agency should calculate future setbacks. A separate entry in the federal regulatory agenda goes further, stating that the Fish and Wildlife Service plans to withdraw the rule and has determined that withdrawal is necessary. The agency hasn’t published that withdrawal yet.

Protecting America’s Duck Factory

The Prairie Pothole Region stretches across Montana, North Dakota, South Dakota, Minnesota, Iowa, and parts of Canada. Its shallow wetlands provide habitat for more than 60% of North America’s breeding duck population and produce an estimated 50-75% of the continent’s primary duck species.

Since 1958, the federal Small Wetlands Acquisition Program has used money from Federal Duck Stamp sales to purchase permanent wetland easements from willing landowners. The land remains privately owned, but the easements prohibit activities that drain or damage protected wetlands. Those protections are now at the center of the dispute.

What the Drain Tile Rule Does

Drain tile consists of perforated underground pipes used to remove water from agricultural ground. A tile system doesn’t need to run directly through a wetland to damage it. Nearby pipes can lower groundwater or intercept water before it reaches a protected basin.

The 2024 rule allows landowners to ask the Fish and Wildlife Service for a site-specific setback before installing tile near an easement wetland. The agency calculates the distance using factors including soil, topography, pipe size, and pipe depth.

Landowners who follow the approved plan receive legal protection if the tile still drains the wetland, provided the system hasn’t been modified or expanded. The rule was intended to protect the easement while giving landowners clearer guidance and liability protection.

Why the Agency Is Reconsidering It

The Fish and Wildlife Service says some landowners believe the setbacks restrict property beyond the wetland areas covered by their original agreements. Many older easements didn’t include specific setback distances at the time of purchase, and some landowners argue that modern calculations limit the use of surrounding land without additional compensation.

The current information request asks the public whether the rule has worked, how setbacks should be calculated, and what changes the agency should consider.

Ducks Unlimited is urging the agency to retain the rule and its longstanding standard that drain tile shouldn’t affect protected wetlands. The organization argues that weakening the rule could allow water to be pulled from wetlands that hunters and conservationists have already paid to preserve.
