Bathing Water Details: Map 1: Bathing Water Location & Extent Bathing Water location and The bathing water at Lahinch is located on the west coast of Clare. extent: The designated bathing area is 0.05 km2 approx in size and extends 300m along the shoreline below the promenade at Lahinch. Main features of the Bathing Type of Bathing Water Water: Lahinch town is built around the bathing area. There is a defence barrier consisting of large boulders above the designated bathing area below the promenade, put in place to prevent coastal erosion. Lahinch is a sandy beach. The beach can be subject to strong waves and strong currents. Flora/Fauna, Riparian Zone The marine riparian zone at Lahinch is classified as heavily modified. Below the rocky defence barrier the bathing area is sandy with the absence of vegetation associated with the upper, middle and lower beach zones. Water Depth The depth of water increases slowly and steadily westward towards the horizon. Tidal Range During the bathing season the tidal ranges vary between 3.5m and 5.3m. Land Use Apart from the town of Lahinch itself land use in the immediate vicinity of the designated bathing area is recreational in the form of Lahinch Golf course. The predominant land use outside the urban area is agriculture. Visitor Numbers Max. number of visitor during a day in high season: 1000 Approx number of visitor during the bathing season: Activities available at the Surfing, including wind surfing and kite surfing, angling and horse riding are all activities that take place at Bathing Water: Lahinch Beach. Clare County Council introduced Beach byelaws in May 2008 under Part 19 Local Government Act, 2001, & Local Government Act, 2001 (Commencement) Order 2006. Under these bye- laws the following activities are prohibited: • Horse riding (between 11am and 6pm) • Dog walking (between 11am and 6pm) • Any use of motorised watercraft • Surfing in the vicinity of swimmers Contributing catchment The Inagh River Catchment and the Moy River Catchment are the main freshwater inputs to Liscannor details: Bay, which may impact on water quality at the designated bathing area in Lahinch. The River Inagh rises in Slieve Callan approximately 32km southeast of the mouth of the river where it flows into Liscannor Bay. This main river body is fed by 7 smaller catchments en route to the sea, namely the catchments of: • Aughaglanna River • Aillenabrockagh River • Ballymacravan River • Dealagh River • 4 smaller unnamed streams The River Inagh flows through Inagh village before passing through Drumcullaun Lough and flows onwards for a further 12km before passing through Ennistymon town and developing into the Inagh Estuary. The Inagh River Estuary is an estuarine channel that flows westwards to the sea from Ennistymon towards Lahinch (8500 p.e.). The estuaries of both the Inagh and Dealagh Rivers converge before O’Brien’s Bridge and enter Liscannor Bay. Immediately south of the designated bathing area three small streams discharge to the sea. All these streams are less than 1 km in distance. The stream immediately south of the designated bathing area is piped to the sea. All streams are located in sewered areas. The Moy River Catchment is located further south of Lahinch. The River Moy is 1.5km in length and discharges into Liscannor Bay approximately 1km south of Lahinch Beach. Overall the water quality status in the catchment is good. The land use in the Inagh catchment is predominantly rural with agriculture as the major land use. Risk from agriculture is classed largely as low with a smaller area (10%) classed as moderate. Wetlands and forestry also make up a small percentage of land use. The four waterbodies classified as poor status under the Water Framework Directive has been for the most part attributed to agriculture or forestry. The landuse of the Moy River catchment is agricultural and carries a moderate risk of pollution. Under the Shannon River Basin Management Plan (July 2010), this waterbody is classified as having good status. Monitoring point details: The designated bathing area is 0.05 km2 approx in size and extends 300m along the shoreline below the promenade at Lahinch. The location of the monitoring point is directly opposite the lifegaurd hut. Reason for selection of the Location where most bathers swim due to its location below the lifeguard hut. monitoring point: Water quality • 2010 -2013 : Excellent. assessment: 3.

Source: Agriculture in the catchment Type: Run off from agricultural land Short Term Pressure: Yes Nature: Low Risk Frequency: very infrequent Duration: < 24 hours Risk Assessment Methodology as recommended in EPA guidance document on preparing Bathing Water Profiles. Methodology: Risk Assessment The Microbial Pollution Potential (MPP) grades for agriculture risk were calculated based on the Results: distance from the bathing area and the agriculture risk associated with a particular area. The agriculture risk is census data based on pressures from cattle and sheep (Department of Agriculture 2000), tillage (Department of Agriculture 2000), and pigs and poultry (Teagasc 2000). For the Shannon River Basin Management Plan (July 2010) results have been applied to agriculture layers of the Corrine 2000 in Mapinfo. Details: Overall within the catchment there is a low risk of diffuse pollution occurring from agriculture during the bathing water season. Farmers are permitted to spread slurry, and other farm effluents, on spreadlands located within the catchment throughout the bathing season. However during times of heavy rainfall there is a risk of runoff from slurry spreading to adjacent waters, which may have adverse effects on the water quality at the bathing area in Lahinch. In the event that there is diffuse pollution from agriculture the duration of short-term pollution would be very short. Management Measures: Ensure that farmers are spreading slurry in accordance with the European Communities (Good Agriculture Practice for Protection of Waters) Regulations 2009. In this regard, it is not permitted to apply slurry to land within 48 hours of heavy rain being forecast. Enforcement notices will be issued to farmers who are not spreading slurry in accordance with European Communities (Good Agriculture Practice for Protection of Waters) Regulations 2009 Environment and Water Services Directorate, Clare County Council.

Management Measures: Regular maintenance and inspections are carried out at the pump stations to ensure that they are in working order at all times.
