Physicochemical parameters of water in earthen ponds and concrete water storage reservoirs in Bakolori irrigation project, Zamfara state, north western Nigeria

Physicochemical Parameters of large Earthen Ponds and Concrete water storage reservoirs (CWSRs) Bakolori Irrigation Project (BIP) were investigated from March 2019 to February 2020. Four sampling stations randomly selected the two body types. Air Water Temperature, Dissolved Oxygen (DO), pH, Electrical Conductivity (EC), Depth, Total Solids (TDS), Transparency & Salinity determined in situ, while samples collected monthly eight taken laboratory for analysis Alkalinity, Hardness, Nitrate-N Phosphate-P. The data arranged on bases seasons (dry wet) five sub-seasons, namely: Early dry (Oct - Dec); mid (Jan Feb); late (March May); rainy (June July) flood period (Aug Sept), subjected T test using Minitab statistical package. Results compared with quality standards Human consumption, aquatic life fish production aquaculture. showed that exception high Turbidity (low transparency) due mud debris reservoir some sub seasons, bodies suitable Aquatic Aquaculture. But partly unsafe human consumption. study recommends continuous assessment physicochemical parameters. It further use several mudfish (such as Clarias Hetrobranchus species) instead leaving them redundant observed during period.
