I am working with similar data for some uncharted areas of BC.
doesn't take these data directly/easily. (If a gpx file is available, you could bring this in, but that might be very cluttered.)
I have been using QGIS to import
these data (I import
xyz files), and then to output various files (including depth
contours though I am not so happy with the contours).
You could create Geotif files which can then be overlaid in OPENCPN
as a transparent layer using Photolayer plugin
. Indeed you could do this using the easily accessed "PDF Plotsheet" provided for each USACE survey
(QGIS can create a geotiff of the cropped pdf, after you use its calibration function.)
