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 Elfin Cove, Port Althorp from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 11.0 ft above it and mean sea level 5.7 ft. These datums are controlled from NOAA's Sitka, AK gauge. Source: NOAA CO-OPS station 9452634, a National Water Level Observation Network gauge, established 1938. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
