An understanding of watershed characteristics like areal, linear and relief aspect has paramount significance for watershed planning and management. An automatic extraction of these characteristics from digital elevation model is so effective and efficient. The main objective of this research work was Morphometric analysis of Lake Langano watershed characteristics from Digital Elevation model using GIS. This research work employs an automatic extraction of hydrological characteristics using Geographical Information system. The results of finding show that the watershed has highly permeable soil type which absorbs the water passing over the soil. Drainage texture of the watershed is very coarse and the watershed is less affected by erosion. There is high runoff in the watershed due to large number of overland flow length. The shape of the watershed is elongated shape and experiences low peak flow over longer duration of time. Circulatory value of the watershed indicates that lake Langano watershed is not under flood risk. Relief characteristics of the watershed indicate that most part of the watershed is characterized by gentle slope and the peak of south eastern part is characterized by steep slope.
