Rivers & reservoirs
A gauge measures water at one station. It cannot tell you the depth at your home or when floodwater will arrive.
Browse island-wide observations
Updating contacts the Irrigation Department’s ArcGIS service. No location is sent. Source record-edit times are not measurement times.
Open the official water mapsOptional ↗
Maps open on the official ArcGIS service in a new tab. Check each station’s date and coverage there. Ark does not send your coordinates.
Reservoir levels and gate releases are not ingested here yet. An open gate, reservoir percentage or nearby river alone does not establish risk at your location.
Sea & tides
A verified local tide feed is not connected. Sea forecasts do not establish river flooding or storm-surge depth.

Sources, freshness & what this tool cannot tell you
Ark is an independent OpenATG awareness tool. It is not a validated forecasting system or an official emergency service. No flood depth, arrival time or safe-route prediction is provided.
River connections, catchments, terrain, releases, rainfall and tides all matter. Straight-line distance cannot estimate flood arrival. Historical and satellite evidence is not a current local warning.
Bulletins are reviewed snapshots. Automatic server-side bulletin publishing is not enabled. River records can be refreshed while the page is open. A successful download does not make an old observation fresh.
Interface translations are provided for access; they are not official translations. Read the original bulletin in your language. Independent native-speaker safety review is pending.
