The following guidelines prepared by the Louisiana State Planning 

 Office are among those recommended for canal dredging in the Louisiana 

 marshlands [73]. 



1. Where possible, existing channels should be used. 



2. Dredging operations should be carried out as quickly as possible 

 in order to limit siltation of oyster beds and other marine 

 areas and minimize extended light reduction.
