Abstract: African reservoirs are under serious threats due to heavy metals pollution as a result of environmental contamination and some anthropogenic activities and their bio-toxic effects on organisms are of great concern. This study assessed the concentration of some heavy metals (Cd, Pb, Fe, Cu, Zn, Cr) in the surface water samples from Bakajeba reservoir, Bakajeba in Niger State, Nigeria from November, 2018 to July, 2019 to ascertain the quality of the water. To determine the heavy metal contents, three sampling stations were collected on the basis of human and agricultural activities as well as the adjoining tributaries which were analyzed by means of standard method of the Atomic Absorption Spectrophotometer (AAS). All the metals were present in the water samples and the concentration gradient of the metals in mg/L followed the following trends Cd (0.45±0.01) > Pb (0.37±0.02) > Fe (0.27±0.11) > Cu (0.27±0.04) > Zn (0.26±0.02) > Cr (0.24±0.10). The concentrations of all the assessed metals in the surface water exceeded the WHO standards for both domestic usage and aquatic productivity. These may have adverse effects on health of the people who utilize the water and aquatic lives in the reservoir
