FACT: Bassman is right...check it out in the KDFW Boating and Fishing Guide. It has been there for a few years now...only pertains to those marina's having a contract with the Corps.
Exactly.........and

Even then does NOT apply to fishing in one's own slip (Buckeye or not)

Q: May I fish around a dock or
a marina?
A: It depends. Public marinas
on U.S. Army Corps of Engineers
Lakes have contractual agreements
that address lease space on public
waters. The Corps presently allows
the marina owners or operators to
post signs that prohibit fishing within
150 feet of their floating structures.
These agreements do not prohibit
a person from fishing in their boat
rental slip. This policy does not apply
to privately owned boat docks on
Corps lakes.
