Which of the following defines a navigable river in Texas?

1. Rivers for recreational purposes

2. Rivers that are shallow and slow-moving

3. Rivers used for commerce or transportation

4. Seasonal rivers with little commercial value

The correct answer is: Rivers used for commerce or transportation

A navigable river in Texas is defined as one that is used for commerce or transportation. This definition is rooted in common law, which characterizes navigability based on whether a river can support commercial trade and movement of goods or services. In Texas, the criteria for a river to be considered navigable typically include sufficient depth and width to accommodate vessels, making it viable for shipping. Navigable rivers are significant because they enhance economic activity and provide essential transport routes. They are also subject to specific regulatory frameworks regarding use and access, especially when it comes to public rights versus private ownership along the riverbanks. In contrast, rivers designated only for recreational purposes may not necessarily meet the criteria for navigability as they may lack the commercial activity or depth required for trade. Additionally, shallow and slow-moving rivers often do not support the types of transport or commerce that classify a river as navigable. Lastly, seasonal rivers with little commercial value do not contribute to navigation in a meaningful way that impacts trade, therefore they do not fit the definition of a navigable river in Texas.
