Hydrometric & Hydrological Data

Real Time Water Level Data – www.waterlevel.ie

This website contains real time water level data recorded at hydrometric gauging stations operated by the OPW. The OPW presently operates surface water gauging stations at over 380 river, lake and tidal locations nationwide and water level data from the majority of these stations are now available in real time.

Archive Hydrometric Data - www.opw.ie/hydro

This website disseminates near real time and quality assessed hydrometric data (water level and river flow) from the OPW National Hydrometric Archive. This includes data from both active and inactive OPW gauging stations. The data from gauging stations operated by the OPW is derived from continuous measurement of surface water levels. At the majority of the sites, discharge can also be estimated through application of a site specific rating curve (known as a stage discharge relationship) developed from a series of flow measurements taken on an ongoing basis.

Along with general station information, quality assessed water level and flow data is presented in various commonly used formats including:

  • Daily mean water level and flow data
  • Water level & flow duration curves
  • Annual maxima water level and flow series

The Environmental Protection Agency (EPA) is required to prepare a national programme for the collection, analysis and publication of hydrometric data in the State and coordinates the implementation of the national hydrometric programme. The OPW, local authorities, and Waterways Ireland own, operate and maintain the vast majority of the existing surface water hydrometric network in Ireland. The EPA provides assistance in collecting data from local authority gauges and in the quality assurance, archiving and dissemination of this data; it also maintains the Register of Hydrometric Stations in Ireland. For further information, see the EPA Hydrometric website.

Flood Studies Update Programme

The aim of the Flood Studies Update (FSU) Programme is the development of new or recalibrated flood estimation methods to significantly improve flood estimation for the purposes of flood risk management. Following the completion of a comprehensive research programme, work is now underway on designing and developing a web-based applications portal to implement extreme rainfall and flood estimation computations at river locations in Ireland, based on the methodologies that have been developed.

Flood Emergency Response Planning Project

The objective of the Flood Emergency Response Planning Project is to assist the development and implementation of effective flood emergency response and recovery plans by the local authorities so as to minimise the impacts and damages caused by flood events.

Hydrology Ireland - www.opw.ie/hydrology

This website, supported and maintained by the OPW for the Irish National Committees for the International Hydrological Programme (IHP) and the International Commission on Irrigation and Drainage (ICID), acts as a focal point for hydrology in Ireland. It is updated on a regular basis to provide access to hydrological data and current information on recently published papers, seminars, conferences and other events.
