The physicochemical characteristics of Kangimi reservoir were investigated monthly at two stations of the reservoir between July 1998 and September 1999. This was done to determine if acceptable water quality standards are being maintained in the reservoir and to assess if the water could maintain a thriving fishery. All the physicochemical parameters investigated fell within the range of allowable standards for potable waters according to the World Health Organization (WHO, 1993) . Alkalinity, conductivity, nitrate‐nitrogen and phosphate phosphorus showed significantly higher ( P < 0.05) values during the rains, which was associated with surface runoff, whereas dissolved oxygen, hardness, transparency and chlorophyll‐a showed significantly higher values ( P < 0.05) during the dry season. The reservoir was indicated to be oligotrophic. The biological significance of these findings are discussed.
