What constitutes navigable waters?

Navigable waters are defined as bodies of water that are capable of being used for interstate or foreign commerce. This encompasses rivers, lakes, and waterways that are deep enough and wide enough to accommodate vessels for transport and trade. Therefore, bodies of water that serve as highways fit this definition perfectly, as they allow for passage and movement that is significant for commerce and transportation.

The term "navigable" implies that these waters are suited for navigation, meaning they must be deep and expansive enough to permit the operation of boats and ships. This is significant not only for commercial purposes but also for legal jurisdiction in terms of federal and state regulations.

The other choices do not accurately reflect the broader definition of navigable waters. Small ponds and streams typically lack the capacity for extensive navigation and commerce. Lakes and oceans, while they may be navigable, do not exclusively define navigable waters, as there are rivers and other waterways that also qualify. Lastly, water sources on private property might not serve the purpose of navigation and do not inherently qualify under the general legal definition of navigable waters, as their accessibility can be restricted and they are not necessarily suited for navigation. Thus, the definition of navigable waters is more inclusive of significant waterways that function as vital channels
