Assessing the Borta Reservoir using physicochemical parameters, Oromia Regional State, Ethiopia


 This study was conducted in the Borta Reservoir (Ethiopia) to portray physicochemical parameters between September 2018 and July 2019 for three data collection sessions. Accordingly, the sampling site was purposely selected perimeter-wise from the Borta Reservoir based on the distance from human settlements; anthropogenic effect and accessibility for the study three stations (sampling sites) were purposely selected perimeter-wise and the sites were coded as Site one (S1), site two (S2), and site three (S3). Water samples were collected monthly for three sample collection sessions. Samples were collected from each site and transported to the Limnology Laboratory and other parameters were measured on-site using a pre-calibrated portable instrument. SPSS version 20 was used for the statistical analysis. The recorded physicochemical parameters were in the range of freshwaters. It was evident that the Borta Reservoir had been showing signs of water quality loss over time. This could have resulted from stressors linked to anthropogenic sources from domestic wastes and pollutants from agricultural lands. This study suggested a restoration action be undertaken.
