This work shows the results obtained from the design of the Earth Dam for the Mekin Hydropower project. This water retaining earth dam design includes the water retaining parts of the main dam and the auxiliary dam. To begin, the basic design data which includes the class of the water retaining structures, flood standard, characteristic water level and fetch length are determined. The work continues with the presentation of the exact location, and the different structures that constitute the earth dam. The dam slope and crest which make up the dam body are also presented followed by their sizing. In addition a study of the seepage-proofing soil and filling material of the dam body is done
