EPA Water Maps

EPA Map – Targeting Agricultural Measures

A farmer-friendly EPA Map on Targeting Agricultural Measures is now available, which has just the key information that will help farmers and other landholders understand their local water quality and where action needs to be taken.

This map has layers with information on:

  • Water Quality Status and Monitoring Stations
  • Targeting Agricultural Measures
    • Targeting Agricultural Measures: this layer shows which actions by farmers have the greatest potential to improve water quality for each area in the country. Where agricultural measures are needed to restore water quality, one or more colours indicate the types of water quality issues in that area:
      • Navy – Phosphorus/Sediment losses
      • Navy and Orange: Phosphorus/Sediment and Nitrate losses
      • Orange: Nitrate losses
      • Red, Orange and Navy– Point Source, Nitrate and Phosphorus/Sediment losses
      • White: Protect measures
    • River Agriculture Pressures – this layers shows all river waterbodies in Ireland where agriculture is a significant pressure. A significant agricultural pressure can be diffuse and/or point source of pollution. Agricultural pressures are subcategorised into pasture, arable, farmyard and agriculture. Many of our waterbodies have multiple significant pressures.
  • Pollution Impact Potential Maps for Nitrogen/Freely draining soils
  • Pollution Impact Potential Maps for Phosphorus/Heavy soils
    • This includes the Pollution Impact Potential Map for phosphorus, and additional layers for overland flow pathways and delivery points which can be used to target interception measures.

About the Pollution Impact Potential (PIP) Maps for nitrogen and phosphorus

ASSAP Advisor Meabh O’Hagan explains what the EPA Pollution Impact Potential maps are used for and how they can be used by farmers to identify water pressures in their area.

Map layers and categories

Any layer can be switched on by using the menu at the top of the map.

The categories and layers are:

  • Water, Land and Soil
    • Water: includes water features like catchments, subcatchments, river sub-basins and water bodies, along with river flow and river network layers
    • Geography: counties, local authority areas and settlements
    • Hydrogeology: GSI bedrock and gravel aquifers, GSI Vulnerability
    • Soil: Subsoils and susceptibility maps for nitrate and phosphate
  • Protected Areas
    • Drinking Water, Recreational Waters (designated Bathing Waters for swimming), Shellfish, Salmonid, Conservation Areas (SACs, SPAs)
  • Monitoring and Flow
    • Q Values – river ecology monitoring results from 1971 to present
    • Flows and Levels – both monitored and modelled, with links to all active hydrometric monitoring gauges
    • National Monitoring Stations
  • Status and Risk
    • Bathing Water Quality – this is updated during the bathing season which runs form 1 June to 15 September and includes links to www.beaches.ie, which has information on water quality, tides, accessibility and weather for all designated Bathing Waters
    • WFD Risk 3rd Cycle
    • WFD Status 2016-2021
    • WFD Status 2013-2018
    • WFD Risk 2nd Cycle
    • WFD 2010-2015
    • High Status Objective water bodies
  • Pressures and Activities
    • Significant Pressures for river, lake, transitional and coastal water bodies
    • Pollution Impact Potential Maps
    • EPA Licensed Activities – Urban Waste Water, waste and Industrial facilities
  • Taking Action
    • Stories – these are all stories from catchments.ie, showing how local communities and public bodies are working to protect and restore water quality in Ireland
    • WFD Areas for Action – this shows the Priority Areas for Action that are being focused on by the Local authority Waters Programme. Further details on all Areas for Action are available at www.catchments.ie/data/#/areaforaction
    • Catchment Projects: areas where there are already projects ongoing at catchment scale, or where funding or plans are in place, which will have benefits for water quality protection/restoration during WFD Cycle 3. They include community initiatives (like Rivers Trusts), LIFE, EIP, INTERREG and public body research projects.
    • Targeting Agricultural Measures: Where agricultural measures are needed to restore water quality, the Subbasin are highlighted with one or more coloured flags to indicate the types of water quality issues associated with that Subbasin.

Satellite Images

This means you can see satellite imagery for any area. This baser layer can be accessed by clicking the three dots in the lower right of the map and selecting ‘Bing Maps’.

If you select the three dots in the bottom right of the screen…
… and then Bing Maps you will get satellite imagery for your map.

Adjusting how your layers look

Once you switch a layer on, you can change how it looks by clicking the ‘Active Layer’ menu on the left of the map.

You can access the Active ;layers menu on the left of the maps…
Once you open the Active Layers menu if you click the icon highlighted above for any layer, you can see the legend and adjust how it looks.
The bar at the top of the screen (in a red box) allows you to adjust how this layer looks. Underneath you can see the legend which explains what the colours mean.
The Water Maps with the Active Layers menu open.

New tools for search, measurement and drawing

Search tools: You can now search by Address, Eircode, County/Town and Coordinates. You can access these by clicking the Magnifying Glass in the top right or by clicking the tools menu on the left of the maps

To find where you live, click on the magnifying glass in the top right….
… and you can find the place you want to know more about.

The Tools Menu: Search for a water feature, measure and draw on your map

The tools menu can be accessed from the left hand side of the map.

  • Search Tools – this is another way to access the Eircode/County/Coordinates search shown above already
  • Measurement Tools
  • Graphic Tools -these allow you to draw on the map
The tools menu on the new Water Map.

Graphic tools

These tools allow you to draw on the map and to add text. You can also print your map after you have added a drawing or text.

These new Graphic Tools mean you can draw or write on you map.

Print Map

This allows you to print the map on screen, along with any shapes or text you may have drawn on the map with the Graphic Tools. You can do this by clicking on the Print Map icon in the bottom right of the Maps.

Click the Printer image highlighted red above to print you map.

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.


Local Authority Waters Programme

The Local Authority Waters Programme coordinates the efforts of local authorities and other public bodies in the implementation of the River Basin Management Plan, and supports local community and stakeholder involvement in managing our natural waters, for everyone’s benefit.


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.
