Hydrology Bulletin, January 2023

The Hydrology Summary Bulletin for January 2023 has information on the flows in rivers, rainfall, lake levels, groundwater levels and spring outflows of over 300 stations across Ireland. It compares January 2023 to long term historical averages for that month.

Overview

Rainfall was below the long-term average in most places and wettest in the southwest. River flows
generally increased since December, with average river flows for January above the long-term
average at over half (53%) of river monitoring stations across the country. Similarly, average lake
levels rose during January, with almost three-quarters (73%) of lakes above the long-term average
for this month.


Average monthly groundwater levels also increased during January. Over half (53%) of monitoring
wells were above the long-term monthly average. Most monitored spring outflows were normal for
this time of year.

Who is involved?

Quite simply, everyone in Ireland has a role to play. This can be from something as simple as making sure you don’t pollute your local stream, or a local community working together to establish a Rivers Trust to enhance the rivers and lakes in their area, to a Government Department or Agency helping a Minister implement a new policy to help protect and enhance all our water bodies.

This website has been developed and is maintained by the Environmental Protection Agency, and is a collaboration between the Department of Housing, Planning and Local Government, the Environmental Protection Agency, and the Local Authority Waters Programme.
