This has a little more history than what is cited.
The original language of the act never really changed, but it was confusing, and so from 1972 until 2016 or so, The Army Corp of Engineers only dealt with NAVIGATABLE waterways.
Then the Supreme Court got involved, and clarified the act, stating that they control most water and wetlands in the United States. I believe it is anything under 5000 feet in elevation. It was a devastating ruling for private landowners. Now, not only is my
land, located high on a hill, and with no sizable streams, still falls under the State Dept of Environmental protection, Federal EPA, and now Army Corp of Engineers.
Here is the kicker. The Army Corp of Engineers never got an increase of funding or staff, so if you file for a
project today, it will be AT LEAST 2-3 years before they can even come out to see your proposed project. But there is a ton of fines to pay if you get caught without the multiple permits.
It is
absolutely insane.
