Well, right under the sea serpent and above the mermaid it says '' 1927
DATUM , Soundings in Feet at MLW''

Low Low Water Low Tide?????

How old is that chart? All of my US charts from the recent past use MLLW

as the datum for
soundings. I even checked in my Chesapeake ChartKit to see if they were

different.

OK - Here's a quiz: What's the meaning of LLWLT?

BTW, I thought of commenting on the "8 feet above MLW" also - around here

we have 10 foot
tides and flooding is measured above MHW

Found the 'old' chart. It reads '' controlling depths in feet at Mean

Low
Water (MLW)''. AND; depths reffered to soundings (MLW)''.

Are you sure?
Don't keep charts at the house, thus the ''I believe'' .

No they are not. Read the chart legend
