Where is my local catchment?

With 46 catchments and 583 subcatchments across Ireland, your local catchment should be an area you are familiar with and know well.

You can find your catchment and subcatchment on the Maps page.

On the Maps page, you can find information about the current status of your local rivers, lakes and beaches. You will also get information about how these valuable resources are being used, and information about the environmental pressures on them.

The Dashboards will give you information about water quality and the significant pressures nationally and for each of our 46 catchments, 583 subcatchments and local authority areas.

On the Data pages, you can see an assessment for each of our 46 catchments and 583 subcatchments.

You can also access detailed results of scientific tests, including long-term trends.

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.

Environmental Protection Agency

The EPA is responsible for coordinating the monitoring, assessment and reporting on the status of our 4,842 water bodies, looking at trends and changes, determining which waterbodies are at risk and what could be causing this, and drafting environmental objectives for each.


Department of Housing, Local Government and Heritage

The Department is responsible for making sure that the right policies, regulations and resources are in place to implement the Water Framework Directive, and developing a River Basin Management Plan and Programme of Measures to protect and restore our waters.
