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 a number of water bodies which are cross border within this subcatchment, and ongoing discussions with the Northern Environment Agency are needed to help identify the significant pressures for these shared water bodies. The two lake water bodies within the subcatchment, Melvin and Lattone, are At Risk; has Moderate 2010-2015 ecological status (driven by macrophytes) and Lattone has Bad ecological status for 2010-2015 (driven by Bad fish status and Moderate total phosphorus). Investigative assessments are needed to determine the significant pressures impacting the fish status for Lough Lattone, with nutrients being the likely pressure for both lakes. It is noted that activities such as fishing take place on both water bodies, and there have been reports of foam forming on Melvin lake on the Northern Ireland side. Both lakes are verified to have the invasive zebra mussel present.

There are a number of areas within the subcatchment that have steep slopes, with runoff exacerbated by the topography likely to be impacting water bodies. Forestry activities involving felling have also been identified. Seven of the river water bodies have unassigned status with no biology or chemistry data available. These water bodies are under Review, given the limited information about the extent of potential pressures within their subbasins and therefore further characterisation is needed to establish water body risks and pressures. Forestry, agricultural activities and wastewater discharges are the main potentially significant pressures.

There is one High Ecological Status Objective water body, Glenaniff_010, which has maintained its High ecological status for 2010-2015.
