Current Tide Level

Real-time tide level shown in feet relative to mean low low water (MLLW) which is the average height of the lowest daily tide recorded at the tide station. The bottom of the Ockway Bay is at approximately one foot below MLLW in shallow areas.  When the needle is in the red boats with a draft of 1 foot are likely to get stuck in shallow areas like Ockway Bay and Mashpee River.  Yellow is the zone where boaters should be careful in shallow areas but should be able to navigate the bay with their outboard motors tilted up.
