navigable waters

Boatable bodies of liquid

Navigable waters are bodies of water deep and wide enough for boats or ships to travel through.

The term has legal significance—in U.S. law, navigable waters fall under federal jurisdiction for purposes of commerce, environmental regulation, and public access.

The river was declared navigable waters, bringing it under Army Corps of Engineers authority.

What counts as navigable varies by context and has been subject to ongoing legal dispute.
