Overall status

11 River Water Bodies - 3 Good, 5 Moderate, 3 Poor. No lakes

Status elements

Q score dictates status, 1 good and 2 moderate sites were extrapolated. Phys Chemical status ranges from high to moderate where monitored. Chemical status not monitored

Possible Impacts - EPA Water Quality 2004

BOTHOGE- Has improved somewhat at Rathtoe Bridge (0100) but weed growth was excessive at both locations surveyed in 2003. Further improvement is required before a satisfactory quality status is achieved. Waterbody Code: SE_14_946 and SE_14_484 – waterbody status 2009: SE_14_946 – Poor (Based on Q value 3) and WB status for SE_14_484: Good (Based on Q value 4)GRANEY (LERR) - This hard-water stream was hypertrophic and heavily silted in Graney (0200) and heavily calcified in its lower reaches (0310) in early September 2003. Unsatisfactory. No change. Agriculture suspected. Waterbody Code: WE_14_620 / 09 Status: Moderate (Based on Q value 3-4) GRANGECON STREAM - Following minor changes at both locations surveyed this stream was assessed as satisfactory (‘Fair’ quality) at Ardsillish Bridge (0100) but slightly polluted and distinctly over-enriched in its lower reaches (0400) in early September 2003: DO at the latter point was 142%. Agriculture suspected. Waterbody Code: SE_14_1635 / 09 Status: Good (Based on Q value 4 in 2006). 07, 08 & 09 monitoring data shows high Ammonium, phosphorus and BOD at Ardsilish Bridge. Suspect Agriculture point source upstream.GREESE –- Despite a significant improvement in the Cross Keys area (0070) where serious pollution had abated, quality was nowhere satisfactory in the Greese River in early September 2003: all but two of the locations surveyed (0100, 0600) were significantly polluted. Industrial discharges are suspected at Cross Keys, sewage at Greese Bank (0200) and a combination of sewage and industrial wastes at Station 0350. Unsatisfactory. Waterbody code: SE_14_1747 / 2009 Status: Poor (Based on Q value 2-3). Agriculture suspected of adding Ammonium and Phosphorus upstream of station 40.LERR - The Lerr River was completely overgrown with the water-weed Apium sp. in Castledermot (0080) in September 2003 indicating considerable trophic enhancement while downstream of the town its quality status was assessed as doubtful at each of the three points surveyed. Sewage from Castledermot is suspected as the main reason for the unsatisfactory conditions below the town but ground-water input is suspected as a contributory factor in the lower reaches (0250, 0300). Waterbody Code; SE_14_377 / 2009 Status: Moderate (Based on Q value 3-4)PALATINE STREAM - Luxuriant Apium sp. growth (total cover) and a lack of sensitive Macroinvertebrates indicated highly eutrophic conditions in this stream in September 2003. Agriculture suspected. Unsatisfactory. No change. Waterbody Code: SE_14_429 / 2009 Status: Poor (Based on Q value 3)

Greese Lerr Water Management Unit Action PlanSELECTED ACTION PROGRAMMENB All relevant basic measures, general supplementary measures and SEA mitigation measures apply

Point Sources WWTP: See table below

INDUSTRY; Investigate discharges at risk.

Examine the terms of all discharge authorisations to determine whether they require review for the purpose of compliance with water body objectives including protected area objectives and environmental quality standards.

Diffuse Sources None

Other

OBJECTIVES

Restore/Protect 2015

7 water bodies

Alternative Objectives

Extended Deadlines – 4 water bodies with 2021 deadline

New Modifications or Development – none requiring alternative objectives at present.

HMWB/AWB - none

FUTURE DEVELOPMENT

Future Pressures and Developments

Throughout the river basin management cycle future pressures and developments will need to be managed to ensure compliance with the objectives of the Water Framework Directive and the Programme of Measures will need to be developed to ensure issues associated with these new pressures are addressed.
