About this Bulletin:
The Hydrology Summary Bulletin provides a factual summary of river flows, lake levels and groundwater levels for the previous month and also includes a comparison to historic monthly values.
The bulletin contains river flow and water level graphs for a sample of surface water and groundwater hydrometric stations across Ireland. The bulletin also contains maps which show how flows and levels at stations across the country compare to the average for the month.
The EPA runs a national hydrometric monitoring programme which measures the flow in rivers, lake levels and groundwater levels at a network of over 350 stations across Ireland. The data is used for environmental assessment, research, and regulatory purposes.
