Eutrophication is one of the pollution problems of aquatic environments. Nitrogen andrnphosphorus are the causal factors for eutrophication, and are creating a problem of algalrngrowth in Angereb Dam. This research was carried out to assess the trophic status of the waterrnin Angereb Dam. A systematic sampling approach was used to select sampling sites from whichrnsediment, soil and water samples were collected and analyzed using standard methods. Thernresults of the study revealed that the trophic status of the water in Angereb Dam was found at thernlevel of mesotrophic condition (4.2Î¼g/L of chlorophyll-a). Total nitrogen and total phosphorusrnwere also found in the water of the Dam at the level that could support the production of algae.rnDissolved oxygen, pH and temperature of the water in the Dam were found at the level that couldrnnot be harmful to aquatic inhabitants. On the other hand, the turbidity level was high. Sedimentsrnand soils of all the selected sub watersheds contained substantial amount of total nitrogen andrntotal phosphorus that could be the source of nutrients to the water in the Dam. Particularly,rnAngereb and Defecha sub watersheds could be the main sources of nutrients to the water in thernDam. Therefore, appropriate soil and water conservation measures are needed to reduce thernoverflow of nutrients to the Dam. Additionally, bio-manipulation techniques should bernundertaken to impede further growth of algae.rnKeywords: Angereb Dam, Eutrophication, Nitrogen, Phosphorus
