STATUS/IMPACTS
River Status
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)
PRESSURES/RISKS

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.

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.
