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 fixes MLLW at Edgerley Island, Napa River from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 6.1 ft above it and mean sea level 3.2 ft. These datums are controlled from NOAA's San Francisco, CA gauge. Source: NOAA CO-OPS station 9415415, established 1979, gauge removed 1979. 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.
