Louisiana Navigability Report


Navigable streams in Louisiana are those that have been or are capable of being used in their ordinary condition for interstate commerce. In navigable rivers, the state owns the riverbed, and the public can use the banks up the ordinary high water mark for activities related to navigation. Acceptable activities include boating, fishing and canoeing.

State Test of Navigability

Louisiana, through its case law, has adopted a state test of navigability that considers streams navigable that are “navigable in fact,” very similar to the federal commerce test.1) A body of water is navigable-in-fact if “it is capable of being used for a commercial purpose over which trade and travel are or may be conducted in the customary modes of trade and travel.”2) The court goes on to say that “simply stated, a water course is navigable when by its depth, width and location it is rendered available for commerce.”3) However, the courts in Louisiana distinguish the fact that a stream “navigable in fact by canoes, row boats and other small craft”, but “not navigable by larger boats and vessels, does not make it a navigable stream.”4)

Navigability is not presumed and the burden of proof rests with the party seeking to establish it.5) In Louisiana, a body of water can also be held navigable despite its natural or man-made obstructions.6) The public trust doctrine applies in Louisiana to navigable waters. The public trust doctrine maintains that the state holds certain lands and waters for the public's reasonable use.

Extent of Public Rights in Navigable and Non-Navigable Rivers

Louisiana follows the federal navigational servitude test which grants the public the right to use and access navigable waters as continuous highways for the purpose of navigation in interstate commerce.7) However, the courts in Louisiana distinguish from this test by fact that not all navigable waters enjoy a navigational servitude as there may be instances non-navigable waters are made navigable by private owners.8) For example, if there is a shallow lake that is non-navigable, and the owner of the lake dredged the bottom to make it navigable for boat travel, the public does not have a navigational servitude to access the lake.

The beds of navigable waters are “insusceptible of private ownership.”9) Banks10) of a navigable river are “private things subject to public use.”11) The public may not utilize the bank of a river or a stream for any activity other than incidental use as it relates to navigation.12) Riparian landowners have the right to reasonable use of the waters but cannot restrict the actual use of a navigable river or stream.13) Courts have not formally addressed the issue of portage outside of the use of navigable rivers banks.

Criminal trespass in Louisiana states that “no person shall remain in or upon property, movable or immovable, owned by another without express, legal or implied authorization.”14) There is an exception to trespass in the statute for an “occupant of a watercraft or vessel traveling on salt water engaged in an emergency purpose for the purpose of retrieval of his property or for obtaining assistance in an emergency.”15)
