1. The 10-yr experience of operating the structures and equipment of the hydrostation showed that the reservoir created by the arch dam provides streamflow regulation for meeting the irrigation needs of 25,000 ha in the Draa River valley and the hydrostation provides the design production of electric energy. 2. The data of inspections of the hydrostation indicate a satisfactory condition of the structures and equipment. 3. The monitoring equipment installed in the dam permits operative monitoring of the safe operation of the dam. About 90% of the installed equipment is operating satisfactorily after 10 years. 4. An analysis of the data of long-term observations shows that at the design head the stresses, strains, displacements, and seepage stability of the dam foundation and bank abutments correspond to the design assumptions.
