Thus, a waterway in its original condition might have had substantial obstructions which were overcome by frontier boats and/or portages, and nevertheless be a “channel” of commerce, even though boats had to be removed from the water in some stretches, or logs be brought around an obstruction by means of artificial chutes. However, the question is ultimately a matter of degree, and it must be recognized that there is some point beyond which navigability could not be established.","path":["Title 33—Navigation and Navigable Waters","CHAPTER II—CORPS OF ENGINEERS, DEPARTMENT OF THE ARMY, DEPARTMENT OF DEFENSE","PART 329—DEFINITION OF NAVIGABLE WATERS OF THE UNITED STATES"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-33.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:25:35Z","sha256":"895024be268b3b5cc55e48ae00d884db3963e38ec484a9e6b3f567e0f4c1a4d4","source_id":"us-cfr","stale":true,"prev":"us/33-cfr-329.9","next":"us/33-cfr-329.11"},"notice":"GroundRules: Original legal text.
