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 Sitka and are referenced to MLLW there. Source: NOAA CO-OPS station 9451468.
