“…1031mg/L while that of the Lake was 5.468±0. 2803mg/L.The DO value in this study of both River and Lake was comparable with the previous study report by Dirisu and Ezenwa (2018) from surface water. The DO value of current study both in the River and Lake Water was lower than the previous report (9.19 ±0.99) by Divya et al (2016) from Tamiraparani River but higher than the WHO (2017) permissible limit.…”

“…The EC value of this finding in the River water (533 µS/cm) was comparable with the previous study report (575µS/cm)by Maryam and Seyed (2022) from Zarrineh River in Iran. The mean EC value of the current finding both in River and Lake was higher than the study recorded in (Dirisu and Ezenwa, 2018). However, the previous study finding by Okey et al(2021) reported higher mean value of EC(756.98 µS/cm) than the present finding in the River (541.4 µS/cm).…”

“…The BOD5 values obtained in this study ranged from 15.2 to 18.8 (mean, 16.268 ± 1.47) mg/L (in the River and from 14.78 to 17.9 mg/L (mean, 16.28 ±1.133 mg/L) in the Lake. The mean BOD5values of the current finding both in River and Lake were higher than the study recorded (3.91mg/L) by Dirisu and Ezenwa (2018) from surface water and (2.43mg/L) by Divya et al (2016) from River.

The study’s surface water bodies, which include the lower Omo River and Lake Turkana in Ethiopia, are the most significant supplies of water for human activities, but they are also severely stressed by environmental factors and are in danger due to human activity. The physicochemical parameters were determined using standard analytical procedures in the Laboratory. The mean BOD5 values obtained in this study were 16.268± 1.47 mg/l and 16.28 ±1.133 mg/l in the upstream and in the downstream respectively. The COD value was higher in the River(upstream) (mean 376.06 ±130.45mg/L) than in the Lake (downstream) (mean 136.00± 41.52 mg/L).The mean fluoride ion level in the River were 0.89 ±0.0135 while that of the Lake was 2.026±0.064mg/l. The mean concentration of total nitrogen were 8.938±1.327mg/L) and 17.84 ± 4.0083mg/L) in River and Lake respectively .The value for PO4-3 was 1.866 ± 0.625mg/L in the River (LOR) while in Lake (ELT) , the concentration was 5.108±0.975mg/L . Mean concentrations for NH3 were 0.54 ±0.361and 1.354 ± 0.655 in the river and lake respectively. The finding of Water quality index (WQI) revealed that the water quality status was very poor and unsuitable for drinking in the lower Omo River and Omo Delta. Hence monitoring the effluent standards from the upstream industries, managing the waste disposal system in the towns along the river side are vital to protect the freshwater from further pollution.

Human encroachment, urban and agricultural expansion, frequent droughts, eutrophication, infestation of weeds, and overexploitation of resources has predominantly impacted the water quality and biodiversity of the Baraila wetland. The present seasonal study has aimed to explore an under-researched subject of analyzing the water quality of the wetland through multi-metric biomonitoring approaches in 2022. A total of 24 water and benthic samples were collected from the four sampling locations. All the water parameters were within a suitable range to support diverse range of flora and fauna, except total suspended solids (TSS) and nutrient, indicating toward the impact of agricultural expansion in the wetland's area. Out of the 13 identified families of benthic macroinvertebrates, the semi-tolerant family of Viviparidae and Bithyniidae has dominated the wetland, with a relative abundance of 27.04 and 37.77%, respectively, in the comparative seasons. Moreover, the indices used in the study has categorized the wetland under moderately polluted condition. The Hierarchical Cluster Analysis (HCA) analysis has revealed the sensitivity toward organic pollution and habitat preferences has played major role in the species-specific assemblage of benthic community. The Mantel's correlogram further validates that the moderately polluted status of wetland has favored semi-tolerant to tolerant fauna in the wetland.
