Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA publishes no datums for this point. Its predictions are offsets from Port Chicago, Suisun Bay and are referenced to MLLW there. Source: NOAA CO-OPS station 9415176, established 1977, gauge removed 1991. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.
