Subcatchment Assessment

WFD Cycle 2 Catchment Mal Bay Subcatchment Doonbeg_SC_010 Code 28_3 2UGQDQFH6XUYH\,UHODQG$OOULJKWVUHVHUYHG/LFHQFH1XPEHU(1 Generated on: 07 Nov 2018 1 Generated by WFD Application Assessment Purpose This assessment has been produced as part of the national characterisation programme undertaken for the second cycle of Water Framework Directive river basin management planning. It has been led by the EPA, with input from Local Authorities and other public bodies, and with support from RPS consultants. The characterisation assessments are automatically generated from the information stored in the WFD Application. They are based on information available to the end of 2015 but may be subject to change until the final 2018-21 river basin management plan is published. Users should ensure that they have the most up to date information by downloading the latest assessment before use. 2 Evaluation of PrioritySubcatchment Issues Four of the seven river water bodies in this subcatchment, as well as the one lake, are Not at Risk: Doonbeg_010, Doonbeg_020, Doonbeg_040, Doonbeg_050 and Namina Lough. The Kilmihil Stream_010 has Poor 2010-2015 ecological status and is noted to have increasing annual average concentrations of nutrients, particularly orthophosphate, and is therefore At Risk. Urban wastewater discharges are identified as the significant pressure, however the wastewater treatment plant is noted to have since been upgraded. The Investigative Assessment will monitor for a decline in nutrient concentrations as a result. Doonbeg_030 also has Poor 2010-2015 ecological status, and therefore the water body is At Risk. Chemistry data indicates nutrients are not an issue, however as the monitoring station is on a tributary in the upper reaches of the subbasin, the impacts are likely related to siltation from forestry operations. An Investigative Assessment will be undertaken to confirm and identify critical source areas for sediment. As there is limited data available for Ballard_010, land use around this water body is similar as for the other water bodies in this subcatchment. As a result, the water body is at Review, and an Investigative Assessment is required to determine its water quality in the first instance.
