What I took exception to was your blanket statement that said all wetlands are Federally protected, which isn't true.
Small isolated wetlands (ie a marshy area in the middle of farmer Joe's field) are not regulated at the Federal level, and only at the state level if their laws are more stringent then Federal law. These may be drained if desired.
By all means, a person should check prior to draining to make sure you aren't in violation.
Also, it should be known that some states, including my own, will help to establish and or improve existing wetlands.
Sorry for the thread derail, just wanted the correct information out there.
