  • Raster Navigational Charts® (NOAA RNCs): bitmap electronic images of paper charts
  • Electronic Navigational Charts® (NOAA ENCs): vector charts that conform to international standards
  • Portable Document Format (PDF)
The US Army Corps of Engineers conduct condition surveys for Humboldt Bay at least twice per year. To view the most recent survey, click US Army Corps of Engineers at the left side of this page to go to their website.
