In 2013 the US Environmental Protection Agency (EPA) released for public comment a draft report, Connectivity of Streams and Wetlands to Downstream Waters, which EPA cited as justification for proposing to redefine “waters of the United States” (WOTUS). Launched in 2014, Farm Bureau’s “Ditch the Rule” campaign generated nearly 7500 postcard comments in opposition from Missouri alone and inspired MOFB’s YouTube hit video “That’s Enough” that generated more than 130,000 views.

In 2015 EPA and the US Army Corps of Engineers issued final regulations redefining WOTUS to include virtually any land feature potentially associated at any point in time with water. Missouri took the lead in a successful court challenge that put WOTUS on hold in 12 states.

In 2017 President Trump issued an executive order directing EPA and the Corps to review WOTUS. With WOTUS on hold pending ongoing regulatory and legal action, the release of a revised definition of WOTUS for public comment is anticipated in 2018.
