DUMPING GROUNDS (Fig. 1) (G-Gb; P-11) 



Dumping grounds are areas designated by the Corps of Engineers for dumping, by per- 

 mit, various types of materials. Generally, such areas are weU offshore or in deep water. 

 If existing depths indicate that future dumping is not intended to cause shoaling sufficient 

 to create a danger to surface navigation, soundings and depth curves may be charted within 

 the area. The area is labeled "Dumping Ground" and tinted blue, if justified by the 

 hydrography. 



The following note shall be used when dumping regulations have been prescribed by the 

 Corps of Engineers : 



DUMPING GROUND 

 Regulations and permission for dumping in area (or areas) 

 indicated, may be obtained at the office of the District Engineer, 

 Corps of Engineers, city state 



When advised that dumping has been discontinued in an area, it shall be so noted and 

 retained on the chart until a survey showing results after final dimaping is available for 

 charting. 



FISH TRAP AREAS (Fig. 1) (P-10) 



The Corps of Engineers, with the cooperation of the Coast and Geodetic Survey, has 

 defined by geographic coordinates the limits of areas in which fishing structures may be placed 

 in Chesapeake Bay and tributary waters. These coordinates are pubhshed in the Code of 

 Federal Regulations, Title 33, Section 206. 



The limits of other areas, although included in above publication, generally are not accu- 

 rately defined and may require supplemental information from the Corps of Engineers for 

 charting. 



The limits of fish trap areas (Fig. 1) shall be shown on charts of 1 :80,000 scale and larger. 

 The following note is used on all charts : 



FISH TRAP AREAS 



Boundary lines of fish trap areas are 

 shown thus: — —(magenta line) 



Caution: Submerged piling may exist , 

 in these areas. 



Due to the large scale, certain affected charts do not contain the entire area, so it wiU be 

 necessary to define the limits as follows :
