The water hyacinth, Eichhorrnia crassipes, has been widely recognized as the worst aquatic weed the world over and of increasing importance in Africa, Ethiopia inclusive. The aim of the research was to highlight the devastating impact of the water hyacinth on aquatic life and human activities on Aba Samuel Dam and to underline prospects of its beneficial use. Delphi technique and on-site observations were used. Eutrophication was found to be the main cause of the proliferation of the plant. However, a majority of its potential uses were identified. The absence of a distinct Ministry of Environment is retarding the efforts in fighting causes of water hyacinth spreading. Community awareness has also been identified as a vital component in eradication of water hyacinth. This research is of significant relevance to environmentalists and ecohydrologists in formulating appropriate strategies and policies for hampering proliferation of the weed.
