It profoundly affects the tropical and subtropical region of the world. In addition, it is recognized as one of the worst weeds and most aggressive invasive species by the International Union for theConservation of Nature (IUCN). In Africa, Zimbabwe is one of the first African countries which water hyacinth was officially recorded. In Ethiopia, it announced in 1956 in Koka Lake and Awash river. Water hyacinth infestation around the Lake Tana is aggravated from time to time. This study was conducted on five woredas (such as Dera, Fogera, Libokemkem, Gondar Zuria and Dembia) which have a higher infestation of water hyacinth coverage. There were about 5394 hectares of water hyacinth areal coverage of the whole woredas at the cost of the Lake. From those woredas, Dembia was holding most areal coverage (2563 hectares) of water hyacinth infestation. To determine the areal extent of water hyacinth around the lake, consecutive ground control truck points was calibrated
