About
A citizen water map for Ireland
WaterWatch is a citizen-powered water map of Ireland. It covers open water (rivers, lakes and coast), bathing waters (both EPA-designated waters and community-added spots), and drinking-water supplies. Anyone can report on open water and bathing; drinking water is shown from official monitoring only. Those reports blend with official data to show where the concern is.
How it works
From what you see to what we know
Anyone can report
See something off, like foam, algae, discolouration, a bad smell, a dead fish, or dumping? Drop a pin and tell us what you saw. No account needed.
Blended with official data
Your observations sit alongside official monitoring and data integrations, so citizen reports and formal records share one map.
A concern reading per water body
Signals combine into a low, medium or high reading, so real issues get noticed and looked at sooner.
