Benthic macro – invertebrates (BMI) are good indicators of surface water qualitybutaquatic pollution in recent times threatens their existence.Information on anthropogenic effluents, BMI abundance and diversity in Gbalegbe River is limited, hence this study.Gbalegbe River (12.5 Km) was spatially divided into eight stations (S1, S2, S3, S4, S5, S6, S7 and S8) comprising three sampling units per station based on dominant anthropogenic activities.Water and BMI samples were collected from each station monthly for 24 months following standard methods.
