Texas Navigability Report


Public waters in Texas include navigable streams, navigable natural lakes, man-made lakes created by damming a navigable stream, and tidal waters affected by tides in the Gulf of Mexico. In Texas, the public may boat, fish, swim, camp, and, in general, carry on any legal activity on navigable streams and other public waters. Texas waters are considered navigable when they are either “navigable in fact” or “navigable by statute.” When public waters in Texas flow over private land, the public may still make use of the waters (e.g., boating or fishing), but may not have legal access to privately held banks or shores. The public has no right to access public waters by way of privately-held lands.

State Test of Navigability

The public's right to navigate inland and costal waterways is one of the rights enumerated in the Texas Constitution.1) Texas streams are considered navigable when they are either “navigable in fact” or “navigable by statute.” The courts have not adhered to any one test in determining whether a stream is “navigable in fact,” acknowledging that a variety of uses may establish navigability. Such uses include boating (both commercial and pleasure), log flotation, and capacity for commercial use.2) The Texas Supreme Court has held waters that, in their natural state for a considerable portion of the year, are useful to the public are “navigable in fact.”3) Streams are “navigable by statute” if they retain an average width of thirty feet from the mouth up.4) The entire width of the stream bed, from fast-land bank to fast-land bank, is included in this measurement.5)

Generally, the beds and waters of streams that are either “navigable in fact” or “navigable by statute” are owned by the state in trust for the public and are subject to use by the public for navigation, fishing, and other lawful purposes.6) Public lakes in Texas include both navigable natural lakes (of which there are few), and man-made lakes created by damming navigable streams. Tidal waters (i.e., waterways connected to and subject to the ebb and flow of the Gulf of Mexico) also are considered public waters in Texas.7) Assuming there exists some means of lawful access, the public (at the least) has the right to boat on and fish from public waters.8)

Extent of Public Rights in Navigable and Non-Navigable Rivers

Typically, the public must obtain access to public waters (and public submerged lands) by lawful means. In other words, to make use of public waters and public submerged lands, members of the general public need to obtain access by way of public lands (e.g., public parks or roadways) or by permission of private riparian owners (e.g., by way of a privately owned campgrounds that permit access to campers). Access over private land without permission of the landowner is considered a trespass under Texas.9)

Members of the public may engage in a wide variety of lawful activities on, in, and along navigable streams. These activities include boating; swimming; wading; camping; picnicking; and (with appropriate licenses) fishing and, in some locations, hunting. Permitted activities are generally limited to the waters themselves and the streambeds. In Texas, streambeds cover that portion of the soil that falls between the “gradient boundary” on each stream bank. The Supreme Court has defined the “gradient boundary as “a gradient of the flowing water in the stream, [which] is located midway between the lower level of the flowing water in that just reaches the cut bank and the higher level of it that just does not overtop the cut bank.”10) In the case of tidal waters within the state boundaries, the state owns the water and the beds and the shores of the Gulf of Mexico and the arms of the gulf, including all land that is covered by the gulf and its arms either at low tide or high tides. The public has no right of passage beyond the gradient boundary or the inland tidal water boundary without the consent of the riparian owner.11)

In the case of man-made lakes, wading and shoreline access will depend not only upon whether the lake is public (i.e., navigable), but also upon whether the submerged land under the lake and the shoreline is public or private. With the exception of “Small Bill” streams (see supra note 6), the issue of wading rights in public waters flowing over privately-held lands appears unsettled.12) In any case, even when public waters flow over privately-owned lands, the public still has the right to boat on and fish from these waters (subject to licensing requirements). This is true in the case of both tidal waters and man-made navigable lakes.13)

The existence of portage and scouting rights in Texas is still unsettled. The Texas Parks and Wildlife Code, for example, states that “recreational use of a protected freshwater area,” including portage and scouting cannot create a “prescriptive easement over private property . . . .”14) The same section of the Parks and Wildlife Code, however, also provides that ”[n]othing in this section shall limit the right of a person to navigate in, on, or around a protected freshwater area.15) Moreover, as already noted, navigation in the state's inland and coastal waters is a right recognized by the Texas Constitution. It is possible (but far from certain) that portage and scouting activities might fall within necessity defense.16)


The Texas Water Code, the Texas Parks and Wildlife Code, the Texas Natural Resources Code, and the Texas Penal Code all contain regulations regarding the obstruction of navigable streams and/or the construction of unauthorized private structures in or along streambeds. For example, the Texas Parks and Wildlife Code generally provides that a person may not restrict, obstruct, interfere with, or otherwise limit the public's recreational use of protected freshwater areas (subject to trespass laws and other legal exceptions).17) The Texas Water Code prohibits the obstruction of navigable streams by cutting or felling trees or by building dikes, bridges, and the like on or across a stream.18) The Texas Penal Code inter alia makes obstructing public waterways without legal authority a Class B misdemeanor. Obstruction for purposes of the Penal Code means rendering the waterway impassable or unreasonably inconvenient or hazardous.19) The Texas Natural Resources Code prohibits the construction or maintenance of non-permitted structures on lands owned by the state. Violations can result in monetary fines and liability for removal costs incurred by the state.20) Under Texas case law, water obstructions also may constitute unlawful purprestures if they encroach on public rights or appropriate that which belongs to the public for private use.21) The Texas Attorney General also has opined that riparian owners may not erect fences on their property that prevent the public from accessing a public waterway by means of a highway right-of-way. Nor can a riparian owner prevent the public from navigating up and down public waterways in boats and fishing by constructing fences stretching across the waterway.22)

The Texas Disaster Act of 1975, codified as Section 418 of the Texas Government Code, authorizes state and local officials to take temporary actions in the case of disasters and impending disasters. These laws most likely give state and local authorities the right to close waterways for reasons of public safety (e.g., high water, contamination, or other dangerous conditions). Actions taken under the Texas Disaster Act cannot remain in effect indefinitely from their inception, but rather are subject to certain review/renewal requirements.

Helpful Internet Resources:

The Texas Parks and Wildlife Department maintains a website with comprehensive information about Texas public waterways. This website includes helpful publications on navigation rights and laws in Texas. See, e.g.,;

The Texas Parks and Wildlife Department (TPWD) is also in the process of creating a interactive catalog of hundreds of public areas used to access Texas rivers, reservoirs and coastal areas. The result will be a comprehensive internet database of public boater access sites for major river and coastal basins throughout the state that includes maps and detailed information about each access site. At present, information is available only for the Colorado River Basin and the Guadalupe River Basin (which served as the pilot project for the database).

According to the TPWD website, data currently is being collected in other river/coastal basins throughout Texas.

The Texas General Land Office maintains a website that provides access and recreation information for areas along the Texas coast.

Civil Revised Statutes, Article 5414a) , Texas relinquished some rights in the beds of some navigable streams to riparian owners (primarily to give these landowners the right to royalties from oil and gas located under stream beds that abutted the landowners property). The Small Bill, however, does not alter the public status of navigable streams or impair the public’s right to use of them. The Texas Attorney General has concluded that the public retains wading rights and the right to walk dry stream beds of streams falling under the Small Bill. Op. Tex. Att’y Gen. S-208 (1956).

Notice can take the form of written or oral notice from the landowner, fencing, visible signage, purple paint markings on trees, and/or crop cultivation and harvesting. Criminal trespass in Texas is a usually Class B misdemeanor, punishable by a fine of up to $2000 and a jail term of up to 180 days. Trespass on agricultural land within 100 feed to the boundary is a Class C misdemeanor, punishable by a fine of up to $500. Trespass may be elevated to a Class A misdemeanor under certain conditions, e.g. if the trespasser is carrying a deadly weapon. A Class A misdemeanor is punishable by a fine of up to $4,000 and a jail term of up to one year. See Tex. Penal Code §§ 30.05(d); 12.21-12.23.
