Inside the EPA – Episode 1: Hydrometric and Groundwater Unit
“Inside the EPA” is a new series that shows a day in the life of our talented EPA staff as they carry out their environmental protection roles across Ireland. In this first episode, we follow the Hydrometric and Groundwater Unit in their mission to measure and monitor Ireland’s water levels and flows.
The EPA monitors river flows and the water levels of our rivers, lakes and groundwater (wells and springs). It does this by operating a hydrometric network of over 350 surface water and groundwater monitoring stations in the Republic of Ireland, as part of the National Hydrometric Programme.
The collected data can be viewed in our monthly national hydrology bulletins, which provide a factual summary of river flows, lake levels, turlough and groundwater levels for the previous month, and on our HydroNet portal.
Other bodies also monitor water levels and flow:
- Office of Public Works (OPW) measures river flows and river and lake water levels in relation to flood management and protection. Further information is available from the OPW on the flood risk management plans and the activities of the Shannon catchment flood risk management group.
- Waterways Ireland monitors and manages the water levels and flows in our canals.
- ESB monitors and manages the water levels and flows associated with our hydroelectric dams.
- Marine Institute monitors sea-level fluctuations around our coasts.
Long-term water level monitoring is also undertaken by institutions such as the Geological Survey of Ireland and Irish Water. It may be carried out in relation to specific activities (e.g. by industry in relation to licence conditions) or for research (e.g. by the agricultural research institute Teagasc).
