Saltwater-Freshwater Line

Fishing Regulations Icon Louisiana Fishing

The saltwater-freshwater line in Louisiana extends easterly from the Texas state line all the way to the Mississippi state line. The areas north of this saltwater-freshwater line are deemed freshwater. The areas south of the described line, including a number of saltwater lakes and waterways, are legally considered saltwater. Although the actual levels of salt in the water may differ from day to day due to tides and shifts in wind and currents, in most cases, the flora and fauna found on either side of the line differ dramatically. A detailed description of the saltwater-freshwater line can be found below. As with any regulation issue, please contact your local LDWF Enforcement Office with any questions you may have.

NOTE: Persons fishing and/or possessing saltwater fish in these areas are required to have a saltwater fishing license in addition to the basic fishing license. Persons fishing for and/or possessing freshwater fish in saltwater areas are not required to hold a saltwater license.
