What describes a "navigable waterway" in Texas?

A "navigable waterway" in Texas is defined as a stream that is navigable either in fact or in law, often determined by the width of the streambed. This definition encompasses waterways that are physically capable of supporting boats or vessels, as well as those deemed navigable by legal standards, which may take into account the historic use or potential for use for commercial navigation. This legal framework allows for public access rights and management of resources associated with these waterways.

The other options do not fully capture the legal and physical aspects of navigability. While a stream that can only be used by boats might indicate navigability, it is too narrow in scope and does not address the legal considerations. Similarly, a waterway with no restrictions on use or one accessible only during certain seasons fails to encompass the essential criteria that classify a waterway as navigable in the comprehensive sense recognized in Texas law. The key factor is the combination of physical navigability and the legal designation of navigable waters.
