Saltwater Locks

[barbarian]

Does anyone know the rules/regulations on the opening of the saltwater barrier near LNG - the one just west of the swing bridge on the Gulf Hwy. I just wondering if a recreational boat wanted to travel through the intracoastal what to expect. Does it open on time intervals, or does it open every time a boat of any kind is traveling through? Do you have to call, radio, or just a visual? I've gone through the locks on the southern end of Calcasieu River, but was wondering about these on the intracoastal. Does anybody know how it works?
