PART 329_DEFINITION OF NAVIGABLE WATERS OF THE UNITED STATES--Table of 
 
Sec.  329.4  General definition.

    Navigable waters of the United States are those waters that are 
subject to the ebb and flow of the tide and/or are presently used, or 
have been used in the past, or may be susceptible for use to transport 
interstate or foreign commerce. A determination of navigability, once 
made, applies laterally over the entire surface of the waterbody, and is 
not extinguished by later actions or events which impede or destroy 
navigable capacity.
