Stations

The Stations tab is a searchable list of gauges: Sentient Things hyperlocal sensors; SECOORA, NERACOOS, and USGS stations (NOAA typically publishes no tide tables there — we use raw observations and compute our own predictions from measurements at that location, which track that waterway more closely even if NOAA publishes a table nearby); and public NOAA stations that provide live or recent readings with NOAA predictions. We do not pad the list with NOAA subordinate estimates that only offset a distant harmonic gauge. Filters sit above the list and can be collapsed.

Stations list and search. Count depends on filters and coverage — not a promise of a fixed number on every device.

Tap a row to open that station. Overview shows a live (or latest) reading and a chart preview. Favoriting a station is for signed-in users.
