	Description:
		Abstract: This dataset consists of locations below the  surface of the water 
			where the depth of water is  precisely known relative to Mean Lower Low Water (MLLW). 
			Soundings were taken at prescribed intervals to determine the current condition of the 
			channel.  Data was collected in the field utilizing Hypack software. Collected 
			information was processed and mapped utilizing Hypack software, 
			Bentley	Microstation V8i and Bentley InRoads v8i.
		Purpose: This dataset is used for channel condition reports and project mapping.
