From the Louisiana Sportsmen's Coalition:
Louisiana is known worldwide as Sportsman’s Paradise and especially when it comes to fishing. However, an alarming situation is threatening your ability to enjoy this public resource. Shockingly, Louisiana is the only state where public access to tidally-influenced water can be restricted. The Louisiana Sportsmen's Coalition is a non-profit, grassroots, membership-driven organization with the sole mission of ensuring public access to tidally-influenced waters.
