One of the EPA’s goals is to make environmental information available to the public and our stakeholders in a timely and accessible manner. In May 2020, we started to publish a monthly national hydrology bulletin.
The bulletin provides a factual summary of river flows, lake levels, turlough and groundwater levels for the previous month. It includes a comparison to the long-term historic monthly values.
The bulletin also contains:
The hydrometric data used in the publication are produced from the EPA/local authority and OPW hydrometric networks. The weather summary information contained in the bulletin is provided courtesy of Met Éireann.
Read the Hydrology Summary Bulletins below.
