Lower Hudson River Mapping Program
Hey all you striper and lower hudson guys, DEC has this "benthic mapper" program that has recent bottom contours for the Hudson from Troy south to NYC. In some select areas, it even has side scan sonar images and bottom content analyzation. I put it up on the Stripers 24/7 hudson board, but there isn't too many people hanging around there this time of year.
Check it out!
