What is a wetland?

The article focuses on the two cases under review by the U.S. Supreme Court, Rapanos v. U.S. and Carabell v. U.S. Army Corps of Engineers, wherein private developers in two areas in Michigan argued against the corps' decision to block development in suspected wetlands because of their proximity to ditches that eventually led to rivers. The Supreme Court said that the federal government can block building on wetlands if it can prove that a continuous waterway connection exists.
