18 NAUTICAL CHART MANUAL 



INTRACOASTAL WATERWAY CHARTS 



The note printed in magenta on the Atlantic Intracoastal Waterway charts gives the project 

 depths and refers to the Notice to Mariners for the controlling depths. For example, the note 

 on chart 843 reads as follows: 



INTRACOASTAL WATERWAY 

 The Intracoastal Waterway is indicated 

 by a magenta line. Distances are shown in 

 International Nautical Miles. 



INTRACOASTAL WATERWAY 

 Project Depths 

 12 feet Norfolk, Va. to Fort Pierce, Flo. 

 8 feet Fort Pierce, Flo. to Miami, Fla. 

 7 feet Miami, Fla. to Cross Bank, Florida Boy. 

 The controlling depths are published 

 weekly in the Notice to Mariners. 



INTRACOASTAL WATERWAY AIDS 

 Intracoastal Waterway aids are character- 

 ized by a yellow band or border. Proceeding 

 from Norfolk, Va. to Key West, Fla.: 



1. Aids with red reflectors ore on the star- | 

 board side; green reflectors are on the port 



side. 



2. Where the Intracoastal Waterway co- 

 incides with another waterway, the dual- 

 purpose aids have distinctive yellow triangles 

 on the starboard side and yellow squares on 

 the port side. 



The article for insertion in the Notice to Mariners is prepared from the Corps of Engi- 

 neers' monthly report on the condition of the Waterway. This article must include detailed 

 information regarding the available depths, such as: "A channel 60 feet wide, 9 feet deep, is 

 available along the west side of the 5.0 foot shoal M niile south of Beacon 128 (chart No. 834)." 



The route lines shall be charted in magenta. When considered necessary, distances in 

 nautical miles, and true course in degrees and minutes (15 minute intervals) may be shown 

 adjacent to the route line, thus: 12M 008°15' TRUE. 



NOTICE TO MARINERS 



Information regarding important rocks, shoals, or landmarks which have been added to, 

 or removed from the charts, should be furnished the Aids Section for publication in the Notice 

 to Mariners.
