What is the definition of "navigable waters"?

The definition of "navigable waters" refers specifically to bodies of water where navigation is possible by boats. This concept is fundamental in boating regulations and environmental law, as navigable waters are typically those that can support the movement of vessels and are therefore subject to certain legal protections and navigational rights.

When considering this definition, it encompasses rivers, lakes, and oceans that are deep enough and wide enough to allow safe passage for various types of watercraft. This distinction is essential for determining where boats can travel and for the enforcement of boating laws and regulations.

The other options describe scenarios or characteristics of water bodies that do not align with the concept of navigability. For instance, bodies of water where fishing is restricted or those intended solely for swimming lack the criteria that define navigable waters, as they do not prioritize the passage of boats. Being shallow and unsafe also does not qualify these waters as navigable, as such conditions would hinder rather than support boat movement.
