Doonbeg Priority Area for Action Desktop Report


Nov 2020

WFD app shows the water quality at Kilmihil stream is at Poor status due to elevated nutrient concentrations

WFD app indicates that sediment is the significant issue and the pressures are possibly forestry and/or an operational quarry upstream

Licence Register No. A0091-01 Kilmihil

The phosphate is likely to be reaching the river through discharge from UWWTP (Kilmihil Urban Waste Water Treatment Plant). Kilmihil wastewater treatment plant was identified in the EPA initial characterisation as the sole significant pressure on the Kilmihil Stream waterbody

EPA notes that this plant is overloaded (i.e. raw sewage is discharging untreated or partially treated to the river)

Last inspection was Nov 2019

Urban Waste Water Agglomerations Impacting on Freshwater Pearl Mussel

This shows all urban areas where improvements to waste water discharges are required to protect freshwater pearl mussel.

The standards set in each EPA waste water discharge licence have been set to achieve the requirements of the Urban Waste Water Treatment Directive and the Water Framework Directive, including the requirement to protect freshwater pearl mussel.

This data set shows all waste water treatment plants in agglomerations (towns/cities) where improvements are required to protect freshwater pearl mussel.


Formats provided do not obviously display the list of sites, needs checking

Does not include private/commercial waste waste treatment sites impacting on FPM

Owenriff Priority Area for Action Desktop Report

Jan 2020


The main pressure in this waterbody is hydromorphology from channelisation, which changing the hydrological and morphological dynamics of the river.

In terms of hydro morphology, there are historic OPW arterial drainage schemes, liaising with the OPW will be required to determine how to restore the waterbodies affected in the Owenriff PAA to their natural habitat. There are also historic land drains leading into the four river waterbodies in the PAA that maybe transporting volumes of sediment to the waterbodies, drain blocking will be required in these cases.

Upper Caragh Priority Area for Action Desktop Report


Feb 2020

High ecological status objective site, currently at Poor status and At Risk

Part of the Caragh Freshwater Pearl Mussel catchment

Important fishery for Arctic char

No water chemistry data available

Hydromorphology and agriculture were identified as the significant pressures

High risk of surface phosphate (and sediment) pathways. Corine land use and soil maps indicate pasture on peat in all three waterbodies, with the risk of ammonia loss to surface waters. Areas of land reclamation carry the risk of sediment loss to surface waters. Pathways may be both point sources (e.g. farmyards) and diffuse (e.g. slurry spreading, overland flow and land drains).

Ogeen Priority Area for Action Desktop Report


Nov 2020

Receiving water (Awbeg (Buttevant)_050 was failing to meet protected area objectives for Freshwater Pearl Mussel

Forestry / clear felling

Pre reg forestry may be responsible for the decline in biology (ortho-Phosphate and sediment).

Possible sediment issue linked to felling associated with windfarm construction. Corine land usage and soil maps show that the bulk of the waterbody is under forestry with much of this on peaty soils. This suggests that sediment is the significant issue impacting on water quality here. Linked to this is a possible nutrient issue (ammonium and phosphate) associated with sediment transport. Forestry felling may have released both sediment and nutrients to the waterbody.

The bulk of the sub-basin is under forestry

Forestry (clearfelling) as the sole significant pressure for Ogeen

Allow Priority Area for Action Desktop Report

August 2018


The Allow is part of the Munster Blackwater SAC which contains Otter, Salmon, Shad, Lamprey and Freshwater Pearl Mussel among others.

The RaptorLife project and IRD Duhallow are active in area with the possibility of ongoing agri-environment projects.

The main risk of diffuse pollution is likely to be phosphate via overland flow as well as sedimentation from modified channels and drainage

Failing to meet protected area objectives for Freshwater Pearl Mussel (19 of 27 catchments of S.I. 296 2009)

North Cork Creameries Co-operative (Section 4 site) – licensed industry with chemistry indicating elevated levels of phosphate and ammonia

Caha Priority Area for Action Desktop Report

Jan 2020


One of the 27 catchments included in the Freshwater Pearl Mussel Regulations (SI 269 of 2009). It is failing to meet the conservation objectives for Pearl Mussel under this legislation.

It is not clear what the issue impacting Caha is. Land use in the catchment consists of pasture and forestry. There is potential for sedimentation of the river substrate from recent forest clear-felling as well as historic quarries in the catchment. Both have been identified as potential significant pressures. Agriculture is primarily low intensity, but there are a few dairy farms in the area.

Coolkellure Lake is a 3.5-hectare (Type 7) lake, located in Coolkellure townland, close to the headwaters of Bandon. It is the drinking water source for Dunmanway (abstraction rate of 550 m3/day). It is currently at ‘Moderate’ status. 

Ecological monitoring in Coolkellure lake indicates a nutrient issue in the lake. Macrophyte and phytoplankton communities both show enrichment.

Forestry has been identified as a potential significant issue in the catchment. The lake is bounded by conifer plantation forestry that has been recently clear-felled. Given the proximity to the lake, steep slopes and peaty soils there is the potential for sediment and nutrient runoff to the lake as a result. Local catchment assessment will focus on the tributary streams to assess from where significant issues might be occurring.

There are two quarries that are no longer operational. Both could have been a source of sediment to the river in the past

Additional information requirements

• Felling records needed for Coolkellure lake and Caha_020

• Additional information from Cork Co Co on quarry discharges in Caha 020

Bleach & Lough Graney Priority Area for Action Desktop Report

March 2020


The PAA is located within the Shannon- Graney/Scarriff margaratifera sensitive area (i.e. catchment with previous records of margaritifera but current status unknown).

Land use is mainly forestry. Forestry is the sole significant pressure on this waterbody.

The significant issue impacting on water quality prior to the 2014 decline is likely to have been sediment and the significant pressure was forestry (probably felling, given the low level nutrient peaks observed).
Lough Graney (At Risk)

Moderate ecological status since monitoring commenced in 2007. Status is driven by macrophytes.

Land use in the sub-basin is mainly agriculture with some forestry to the west and north. Agriculture, and forestry are likely the significant pressures on this lake.

The significant issue impacting on water quality is most likely to be phosphorus.

Stream walks are required to identify whether pathways exist between forested areas and the river/its tributaries

Additional information requirements

Talk to Forest Service staff to obtain more detailed information on felling, particularly in the Bleach_010 headwaters during the period Summer 2012 to Summer 2014.

Also obtain information on aerial fertilization programmes undertaken here in the past.
