Frequently Asked Questions
Everything you need to know about Irish river levels, OPW and EPA hydrology data, typical ranges, spate behavior, and river safety.
How often is Irish river level data updated?▼
River levels (metres) and discharge flows (cumecs, m³/s) are updated every 15 minutes utilizing automated cellular telemetry directly from the Office of Public Works (OPW waterlevel.ie) and EPA Ireland across all 26 counties.
What do typical normal low and high ranges mean on Irish river gauges?▼
Typical flow ranges represent long-term seasonal baselines. Readings below the typical low indicate summer low flow with weed build-up, within range indicates prime navigable or angling conditions, and above the typical high warns of spate conditions, heavy current, and potential out-of-bank flooding.
How does the River Activity Score work for Irish waterways?▼
Our algorithm computes an activity score (1–10) tailored specifically for Wild Swimming & Dipping, Canoe Touring & Blueways, Whitewater Kayaking, or Salmon & Trout Angling. It analyzes real-time discharge, hydrograph stability (rising vs. falling spate), water temperature, solunar fish feeding periods, and rainfall forecasts.
Which Irish counties and provinces are covered?▼
Riverable Ireland covers all 26 counties across Munster (Cork, Kerry, Limerick, Clare, Tipperary, Waterford), Connacht (Galway, Mayo, Sligo, Leitrim, Roscommon), Leinster (Dublin, Kildare, Wicklow, Wexford, Carlow, Kilkenny, Laois, Offaly, Westmeath, Longford, Meath, Louth), and Ulster (Donegal, Cavan, Monaghan).
What safety guidance applies to canoeing, wild swimming, and angling in Ireland?▼
Always check live river levels before launching, beware of hazardous weir stoppers and back-washes, scout rapids, wear an approved PFD lifejacket, check for submerged hazards, and practice Check-Clean-Dry biosecurity to protect native salmonids.
Can I embed Irish river gauges on my angling club or tourism website?▼
Yes! We provide 100% free embeddable responsive river level and flow widgets. Visit our Widgets page to generate iframe snippets for any gauged river in Ireland.
