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 Seldovia, Kachemak Bay from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 18.0 ft above it and mean sea level 9.6 ft. Source: NOAA CO-OPS station 9455500, a National Water Level Observation Network gauge, established 1964. 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.
