2 STATUS/IMPACTS Overall status Status elements Possible Impacts - EPA Water Quality River Water Bodies - 16 Good, 22 Moderate, 8 Poor, 2 Bad Q score dictates overall status in most WBs, Phys Chemical drives the status of 3 good and 2 moderate WBs. Phys Chemical status ranges between moderate and high where monitored. Status for 23 WBs were extrapolated. Chemical status was not monitored. ATHY STREAM - Upper reaches (0200) heavily silted and weedy, lower reaches heavily calcified. Sensitive species not observed at either location. Unsatisfactory. Agriculture suspected. *Silt. Waterbody Code: SE_14_1288 / Status 09: Moderate (Based on Q value 3-4) AUGHNACREW - An impoverished fauna lacking sensitive macroinvertebrates indicated some considerable ecological upset in the middle reaches (0300) of this stream in October 2003 but the lower reaches (0500) although quite weedy were assessed as satisfactory for the time being. Waterbody Code: SE_14_1921 / status 09 : Moderate (Based on Q value 3-4) BALLYNABOLEY STREAM - As in previous surveys indications were of somewhat less than satisfactory quality in this small stream in Unsatisfactory. No change. Waterbody Code:SE_14_951 / Status 09: Poor (Based on Q 3) BARROW - As indicated by the net increase (of two) in the number of Class A locations and a corresponding reduction in Class C and because the number of locations showing some improvement (six) the number deteriorating (three) it is clear that there has been an overall improvement in the Barrow since This despite the fact that water levels were generally below normal everywhere and were very low in the upper river thus providing less dilution capacity for wastes. However, eutrophication continued to be widespread due to suspected agriculture in the upper river and to suspected sewage and other discharges from Portlaoise and Carlow. DOUGLAS (LAOIS) - The overall quality situation in the Douglas river in 2003 was very similar to the generally unsatisfactory condition recorded in the previous survey: marked eutrophication was again apparent at 0080 and 0200 and the lower reaches (0300), although slightly improved since 2000, were heavily silted. Severe bank erosion was apparent at the upper surveyed location (0080).*Silt. Waterbody code: SE_14_1304 / Status 09: Good (Based on Q4 in 2006);SE_14_1490 Status 09:Good Based on Q Score and Physchem. DUNRALLY STREAM - Widespread eutrophication plus heavy siltation by watering cattle in the lower reaches again reflect the unsatisfactory quality status of this stream. High conductivity values indicated a groundwater input at Stations. *Silt. Waterbody Code: SE_14_1746 / 2009 WB status: Moderate (Based on Q value 3-4) FUER -As in 2000 extremely low water level prevented sampling but from the quantities of animal manure observed on the substratum at Fuer Bridge it would be reasonable to assume that quality was unlikely to have been of a satisfactory standard in Waterbody code: SE_14_1482 / 2009 WB status:moderate:based on fail in physchem) FUSHOGE - Following a marked improvement in its lower reaches (0290) water quality was assessed as satisfactory at each of the three locations surveyed on the Fushoge River in early October However, heavy siltation and substratum disturbance by watering cattle threatened this situation at Strand Bridge (0050). Waterbody Code: SE_14_ Status 09: Moderate (Based on physchem) GOWRAN - The Gowran River was in a generally unsatisfactory condition due to widespread eutrophication in October 2003; just one of the six locations surveyed (i.e., 0050) was satisfactory. Abundant sewage fungus and the virtual absence of resident macroinvertebrates pointed to serious pollution of agricultural origin (silage suspected) in the Freneystown area (0020) while municipal and industrial discharges are suspected for the unsatisfactory, hypertrophic condition of the river in and below Gowran (0100, 0220, 0300 and 0400). (Since survey in 2003, there has been a new WWTP at Gowran Village in 2009) Waterbody Code: SE_14_ status: Poor (Based on Q value 3-4) MONEFELIM - The Monefelim River was in a mostly satisfactory condition as regards water quality in October 2003 but the lower reaches (0800, 1000) were assessed as eutrophic due to suspected agriculture (slurry), a reversal of the recovery recorded in the previous survey of Waterbody Code: SE_14_ Status: Moderate (Based on Q value 3-4) OLD LEIGHLIN STREAM - Water levels were very low in this small stream in October 2003 when quality was assessed as satisfactory at Old Leighlin (0500) but excessive algal growths indicated significant eutrophication in the lower reaches (0700) where the DO concentration was 158 percent of saturation at the time of this survey. Waterbody Code: SE_14_1382 Status 2009: Moderate (Based on Q value 3-4) POWERSTOWN - An improvement to Fair quality was recorded in the lower reaches (0400) of this small stream in late July The upper reaches were again over-enriched as in previous surveys. Waterbody Code: SE_14_1383 / 2009 status: Good (Based on Q Score) TULLY STREAM - Minor improvements at 0100 and 0200 contrast with substantial deterioration at 0300 and 0390 where the river was seriously polluted at the time of this survey in late August Waterbody Code: SE_14_842 / Status 09: Bad (Based on Q value 2 and fail on physchem) 4% 17% 46% River Status 33% High Good Moderate Poor Bad Yet to be determined
