The maps are available in PDF format using the free Adobe Reader. They were created to provide boaters and other users with general channel condition maps that are easier to read than the standard hydrographic survey maps. They are updated periodically with the latest hydrographic survey data for each project. Dates for each survey are noted on the maps.

NOTE: The condition surveys depicted on these drawings are not intended to replace nautical charts published by National Ocean Service, U.S. Coast Guard aids to navigation, or U.S. Coast Guard Notices to Mariners. The soundings on these drawings only indicate the general condition of the channel on the date of the survey and are not intended to be used for navigational purposes.
