Updated October 18, 2026. A canal may connect to a public waterway without every part of its bottom, bank, or shoreline becoming public property. A privately owned canal may also carry a legally enforceable right of passage. The first step in an access dispute is to identify the right being claimed: ownership, navigation, crossing the bank, fishing, or leaving a boat tied up. Those rights do not necessarily belong to the same people or cover the same ground.
The issue is immediate for residents near Manchac. Unfiltered with Kiran reported on October 17, 2026 that boat owners received removal notices concerning a canal and that questions remained about ownership, rights of way, and historical records. That reporting identifies the dispute; it does not establish the legal boundaries or resolve the competing claims. This guide explains the records needed to examine those questions without deciding who owns that particular canal.

| Question | Records and law to examine | What does not answer it by itself |
|---|---|---|
| Who owns the bottom or bank? | The chain of title, surveys, historical waterway evidence, state claims, and relevant judgments. | A familiar place name, tax map label, or the fact that boats can reach it. |
| Who may navigate through the channel? | The waterway’s legal status and any public or private navigation servitude, including its boundaries. | Private ownership alone does not eliminate every possible servitude; public access elsewhere does not establish one here. |
| Who may tie up, build a dock, or occupy a slip? | A lease, permission, applicable servitude language, permits, and other governing restrictions. | A right to travel through a channel does not, without more, establish a right to keep a boat there. |
Consider a hypothetical channel crossing private land under an instrument that permits public navigation. That arrangement could protect passage while leaving the land privately owned. Whether it permits mooring depends on the instrument and applicable law. Conversely, a boat-slip lease may permit a tenant to occupy a berth without opening every neighboring bank to the public.
Louisiana’s public-water rules are the starting point
Civil Code article 450 classifies running waters and the waters and bottoms of natural navigable water bodies among the public things belonging to the state. Article 452 addresses public use, subject to governing laws and regulations and without injury to neighboring property. These provisions matter, but applying them requires identifying the water body and the property interest at issue.
Article 456 separately addresses the banks of navigable rivers and streams. Those banks are private things subject to public use, and the article defines the bank by reference to ordinary low and high stages, with a rule for levees. It is not a general declaration that every waterfront yard, artificial canal edge, or dry tract reached during flooding is open for any activity.
Historical navigability can be central to a state ownership claim. The Office of State Lands investigates titles, boundaries, and navigability and maintains relevant historical records. Its role, and the state water-bottom framework in R.S. 41:1701, make state records an important part of the inquiry. A modern aerial photograph showing water cannot replace the historical and title analysis.
An artificial channel presents additional questions: who owned the land when it was excavated, what was acquired for the project, whether a natural channel was changed, and what rights were reserved or granted. “Man-made” and “connected to a river” describe physical characteristics. Neither phrase supplies the missing deed, servitude, or judgment.
Read the actual servitude, including its limits
A servitude is a legally recognized right affecting property. For conventional predial servitudes, Civil Code article 697 directs attention to the title creating the right: that instrument regulates its use and extent. Article 730 resolves doubt about the existence, extent, or manner of exercising a predial servitude in favor of the property burdened by it. Broad claims of access therefore require more than the word “servitude” on a map.
Obtain the signed instrument and every incorporated exhibit. Identify the parties, the property benefited, the property burdened, the purpose, the width or legal description, and any duration or termination provisions. Then determine whether later recorded instruments, judgments, or changes in ownership affect the right. A surveyor can locate a described corridor; a title examination addresses the legal interests within it.
A railroad, drainage, highway, or utility servitude may serve a specific purpose. Its existence does not automatically create a recreational boating right for everyone. Likewise, an agency’s maintenance activity may be relevant evidence without proving that the agency owns the entire canal or has authority to license every private use.
What the state’s water-bottom map can and cannot establish
The Office of State Lands’ water-bottom data explanation expressly treats its maps as a starting reference rather than proof of legal title. The mapped water outline may differ from the legal extent of a state claim. The categories also distinguish state claims, public access, competing claims, and areas governed by judgments or agreements.
Those categories are useful leads. A public-access designation may point to a navigation servitude even where the state does not claim ownership of the bottom. The agency also explains that channel erosion does not necessarily enlarge a servitude beyond its original boundaries. Save the map’s date and category, then request the underlying documents. Do not treat the present shoreline on an aerial image as the legal boundary of the right.
A federal navigation argument is not a blanket permission to fish
In Parm v. Shumate, 513 F.3d 135 (5th Cir. 2007), the court rejected asserted federal and state rights to recreationally fish over ordinarily dry private property temporarily covered by Mississippi River floodwater. The decision illustrates why the public character of a river does not automatically settle access to adjoining flooded land.
The case did not decide ownership of the canal in the Manchac reporting. Its practical lesson is to identify the precise legal basis for the proposed activity. A reference to navigability, federal authority, or nearby public water is not enough to establish a permanent mooring or fishing right at a disputed location.
Build a record that connects the claim to the location
Scroll horizontally to see all columns. Use the arrow keys when the table is focused.
| Document | Where to begin | Question it helps answer |
|---|---|---|
| Current deed and earlier conveyances | Parish clerk of court conveyance records; documents identified in the claimant’s title. | What property was conveyed, by whom, and subject to which reservations or recorded rights? |
| Recorded servitudes and attached plats | Clerk of court records and the agency or entity named in the instrument. | Who holds the right, for what purpose, and within what boundaries? |
| Expropriation petition, judgment, and exhibits | The court file and the acquiring agency’s project records. | Did the acquisition convey ownership or a narrower right, and what land did it cover? |
| Historical channel maps and state title materials | Office of State Lands and the public agencies responsible for the relevant project. | What supports a state ownership or public-access claim, and has the location changed? |
| Professional surveys and legal descriptions | Recorded plats, title files, and a Louisiana land surveyor. | Where do the described parcels, original channel, and servitude corridors lie on the ground? |
| Lease, dock agreement, permission, and correspondence | The boat owner’s records and the person claiming authority to grant use. | Was mooring authorized, on what terms, and was that authority sufficient? |
| Prior judgments or settlement instruments | Court records and recorded instruments identified in the title history. | Has a court or binding agreement already resolved part of the dispute? |
Keep a short chronology alongside the documents. Record the canal’s construction or alteration, each relevant acquisition, each servitude, any judgment, and the beginning and terms of the claimed use. If an old description refers to a channel that moved or widened, flag that discrepancy for the surveyor and lawyer. Combining documents without reconciling their dates can make incompatible boundaries appear consistent.
If you receive a removal notice
Keep the notice, envelope, photographs, prior agreements, payment records, and relevant correspondence. Record its delivery date, stated deadline, claimed owner, and description of the affected area. Ask for the documents supporting the claimed ownership and authority to demand removal, including the legal description and any applicable lease or termination provision.
A useful written inquiry can be limited to the missing information: “Please identify the recorded instrument and property description supporting the claimed right to require removal from this location, provide the relevant survey or exhibit, and identify any agreement under which you contend our permission has ended.” A request for documents does not extend the deadline or create permission to remain.
Obtain prompt advice about the actual notice and any court papers. If additional time is needed to investigate title or arrange a safe move, seek a written agreement. Do not assume that years of tolerated use, a disputed map, or a pending conversation with an official defeats a removal demand. Those facts may matter, but their effect must be evaluated under the applicable property and procedural law.
The most useful next step is usually a focused title-and-access review: the exact location, the exact activity, the instrument supporting each side’s position, and the relief each side is seeking. That produces a question a surveyor, agency, or court can answer.
