Mean Lower Low Water (MLLW) - There are two low tides in each tidal cycle (so usually two low tides in each day).

The Mean Lower Low Water Level (chart depth) at the west bank is 7.9 feet. At the time of our crossing, there was approximately 3.0 feet of tide height above the Mean LLW (chart depth). Our boat's draft was 5.7 feet.
