The Hanalei River decides a lot of days on the North Shore. This app tells you
where it stands, in one number, plus everything you need to read it.

THE RIVER RIGHT NOW
Open the app and the river's height sits at the top of the screen, in feet,
next to what it means against the 5 ft flood stage: Normal, Elevated, Near
flood stage, or Flood stage. A trend chip says whether the river is rising,
falling, or holding, and by how much in the last hour. Every reading is stamped
with its age, and when a gauge goes quiet or the USGS equipment fails, the app
says so. An old number never gets dressed up as a live one.

THE LAST FEW DAYS AT A GLANCE
A stage chart plots recent gauge history, with the flood line drawn in whenever
the river is anywhere near it. You see a squall's rise and fall, not just this
minute's reading.

LIVE ROAD CAM

own, so it keeps working when the broadcast restarts.

WEATHER THAT LEADS WITH WHAT MATTERS
Watches, warnings, and advisories in force for the North Shore come first, not
buried in a technical narrative. Under that, the seven-period NWS forecast with
temperature, wind, and chance of rain, and the full forecast discussion from
NWS Honolulu when you want the reasoning behind it. Active flood alerts show up
on the river screen too.

TIDE AND DISCHARGE
A tide curve for the day ahead with the next high or low called out, plus the
river's discharge in cubic feet per second.

EVERY GAUGE ON KAUAI
One tab, one row per river: current level, direction, and a sparkline of recent
readings. Hanalei, Wailua, Waimea, and the rest — the whole island in a few
seconds of scrolling.

ON YOUR WRIST
The Apple Watch app keeps current height, reading time, discharge, and the next
tide a glance away.

NO ACCOUNT, NO ADS
Nothing to sign up for. Pull to refresh, or just reopen the app and it updates
itself. Full dark mode, so a 2 a.m. check doesn't light up the room.

Readings come from the USGS gauge on the Hanalei River, tide predictions from
NOAA, and alerts and forecasts from the National Weather Service.

A gauge reading is not a road report. The app can tell you the river has
reached flood stage; it cannot tell you whether water is over the road. Follow
county and emergency guidance, and never drive through moving water.
