Physico-chemical variables were determined using standard methods, A total of 1304 macroinvertebrates were recovered. Twenty-seven taxa were recorded. The higher number of taxa (23) was recorded at station 2. The abundance of individuals was highest at station 3. The presence of low densities of pollution tolerant macroinvertebrate groups, the deteriorating water quality and the physco-chemical conditions of the water during the dry season months was a reflection of organic pollution stress caused by decomposing domestic refuse and inorganic fertilizer washed into the stream by irrigation.

INTRODUCTION Most major cities contain a number of waterways such as bays, harbors and rivers together with a small network of small streams. In Nigeria most of these streams have been subjected to an increasing pollution load from contaminated urban run-off water originating from industrial, agricultural, residential, commercial and recreational areas and institutions such as schools and hospitals (Adakole and Annune, 2003). Ogbogu and Hassan (1996) pointed out the effects of contaminants usually flushed into streams especially in areas of high human activities. Macroinvertebrate organisms form an integral part of an aquatic environment and are of ecological and economic importance as they maintain various levels of interaction between the community and the environment (Anderson and Sedel, 1979). According to Marques et. al. (2003) knowledge of the structure of the benthic macroinvertebrate community provides precise and local information on recent events, which can be seen in their structuring. The use of invertebrates and fish as bioindicators of water quality has been advocated by several researchers (Victor and Ogbeibu, 1985; Ofojekwu et. al., 1996; Edokpayi and Osimen, 2001; Adakole and Annune, 2003). The Barnawa stream is the main drainage system of most parts of Barnawa, an urban settlement in Kaduna metropolis. Although it is not a major river for fisheries activities because of its size it is the major effluent receiving stream in Barnawa as many gutters are linked to it. It is also used
