Lake level change is fluctuation of water level within the lakes that resulted from the shiftingrnof water balance from its static state. At national scale, the Ethiopian lakes level change wasrnnot studied yet using remote sensing method and there was no well-organized geodatabase thatrnshows their spatial variation with specified time interval. Therefore, this was the biggestrnchallenge in order to identify whether the lakes are in dynamic or in steady state. This studyrnaims to solve the above mentioned problem through assessing the Ethiopian lakes level changernby developing well-organized geodatabase and identifying the endangered lakes for the lastrnfour decades using Landsat satellite images (Landsat MSS, TM, ETM+ and OLI sensors). Thernresult shows that there are 108 natural and man-lakes and from these lakes endangered lakesrnwere identified with ranking their spatial extent fluctuation. Accordingly, Lake Abiyata,rnChamo, Chelelek and Haromaya, ranked top three declining lakes, and Lake Beseka, top onernrising lake, was identified as endangered lakes. Furthermore, Lake Abiyata and Chamo werernshrunk by 33.59% (66.64 km2) and 8.98% (29.43 km2) respectively and Lake Beseke wasrndrastically raised by above 900% compared to their 1970â€™s spatial extent. However, LakernChelelek and Haromya were desiccated before 2010â€™s due to anthropogenic factors. The mainrnfactors considered in this study was the Land use land cover of the lakes surrounding and overrnconsumption of the lakes water. Moreover, the verification for identified endangered lakes wererndone using the field collected coordinates of the lakes edge and the trend of water level of thernlakes measured by Ministry of Water, Irrigation and Energy. Due to the drastic decline, LakernAbiyata needs special rehabilitation practice and Lake Beseka also needs proper treatment.rnFurthermore, the final result of this study used as a benchmark for the coming researches.rnKey words: Landsat image, lakes level change, endangered lakes, Ethiopia, geodatabase
