Question 460Navigation General

The correct answer is C) indicated by a broken line. On the Corps of Engineers' navigation maps, the channel is typically indicated by a broken line. This broken line represents the navigable portion of the waterway, denoting the area where vessels should operate. The broken line helps mariners visually identify the safe, recommended route to follow. The other answer choices are incorrect because: A) the channel is not simply omitted from the map, B) the depths are separately indicated, and D) the channel is not necessarily located midway between the banks, as it may meander or be offset.
