Subcatchment Assessment

WFD Cycle 2 Catchment Lower Shannon Subcatchment BROSNA_SC_070 Code 25A_11 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 There are 6 river waterbodies in this subcatchment. 3 are NOT AT RISK - Brosna 120 ( wehich is High Status in 2013- 2015) and Brosna 130 and Silver (Kilcormac)_040 both with improved or maintain Good ecological status in 2013-2015. 2 Unassigned river water bodies Kilnagall_010 and Kyleboher_010 are now AT REVIEW and will which require investigative monitoring. Silver (Kilcormac)_050 is AT RISK due to the Moderate Status assigned in the 2013-2015 cycle. This was mainly driven by Fish status but also moderate total organic nitrogen (TON). Rehab works have been recently undertaken by IFI with BNM and ESB for instream fisheries rehab works that includes gravel and weirs. Fish status is anticipated to improve, with monitoring of this required. The water body has also been flagged as High Priority for a hydromorphological desktop risk assessment. The significant pressures within the catchment range from hydromorphology, agricultural atctivities and peat extraction.
