Harbour Survey

The Fowey Harbour Commissioners carry out an annual programme of surveys including Bathymetric and Side scan surveys in order to ascertain the navigable depths within the harbour, to maintain the shipping channel for commercial shipping.  

The survey information is used to inform the dredging protocol to ensure that dredging is efficient and effective.

The three extracts illustrate the seabed in Fowey during the 2006 surveys. Depths are colour coded as per the colour code bar on the left hand side of each drawing.


Key points to note are as follows

Heights are relative to Chart Datum. 

The scale of the depths has been multiplied relatively to the plan position in all drawings. The size of multiplication is between  x 2 and x 10, depending on location. 

The drawings are for illustrative purposes only and not to be used for navigation. 

Shoreline Surveys Limited have produced these drawings on behalf of the Fowey Harbour Commissioners.
