Yellow indicates reported depths below 12 feet, red indicates depths below 6 feet.

Note that these observations reflect the tide at the time, have not yet been corrected or added to the database for collective processing, and should NOT be used for navigation. Nonetheless, assume high tide and take advantage of the chartplotter on the boat in front of you. These reports will be available on the web site shortly, and we will provide future updates as appropriate.
