Abstract: Construction of micro dams to harvest the available surface water resources of dry land area is inevitable. Elbahi micro-dam is located near to Jigjiga town in Ethiopia Somali Regional state; it was constructed from 1986-1993 with multi-purpose dam to serve the community as a source of water supply for irrigation, domestic and livestock consumptions, and to protecting Jigjiga town from flood problems. Elbahi-micro dam watershed has bi-modal rainfall distribution. The larger amount of mean monthly precipitation of Elbahi-micro dam watershed received during the main rainy season which extends from March to May while the second rainy season when lesser amount of mean monthly precipitation received extends from July to September. The mean annual precipitation in Elbahi micro dam watershed is estimated as 550.1mm. The major soil classes in the Elbahi micro-dam watershed are; Dystric nitisols (48%), Vertic cambisols (50%) and chromic luvisols (2%), which affect soil degradation differently.
