Problems with cost array generation

We are using hydrography maps from NOAA since all our work is in the ocean and rivers of North America.
I am getting my cost raster and backlink rasters generated.  However the results seem to ignore land.

The values are listed for the cost array as 0 -> 6xxx and I wonder if the 0 values is the issue.  Can't confirm but I think the land areas may have a value of 0 instead of NoData. 

Any suggestions?
