Abstract

Reservoirs, as critical water resources, serve diverse purposes such as irrigation, fisheries, and domestic water supply. This study evaluates the physicochemical parameters of Sabke Reservoir in Katsina State, Nigeria, with focusing on understanding their ecological impact and pollution status. The research, conducted between June and November 2024, analysed parameters such as temperature, pH, turbidity, dissolved oxygen (DO), biochemical oxygen demand (BOD), total dissolved solids (TDS), and conductivity across three sampling stations (upstream, middle, and downstream). Measurements were taken following APHA standards and subjected to statistical analysis using ANOVA and the Duncan Multiple Range Test at a 95% confidence interval. Results revealed significant seasonal and spatial variations in the reservoir’s physicochemical parameters. Temperature ranged from 27.96°C to 30.00°C, with higher values observed during October. Turbidity peaked at 55.83 NTU in November, exceeding WHO permissible limits and reflecting sedimentation and runoff impacts. pH values remained neutral to slightly acidic (6.32–6.89), suitable for aquatic organisms. DO concentrations (5.09–5.63 mg/L) were stable but slightly below WHO recommendations for aquatic life. TDS values (319.3–397.3 mg/L) exceeded permissible limits, correlating strongly with conductivity (r=0.617, p<0.01), indicating increased ionic concentrations. The study underscores the influence of seasonal changes and anthropogenic activities on water quality. High turbidity and TDS levels pose potential risks to aquatic biodiversity and ecosystem functionality. These findings are consistent with studies across Nigeria and other tropical regions, emphasizing the need for integrated management strategies to mitigate pollution and sustain the ecological health of reservoirs.
