44 about 25 miles from Kandahar, and (3) extension of the Boghra canal some 35 miles into the Dasht-i-Margo, and also another branch-canal some 65 miles long, following the flood plain of the Helmand near the village of Shamalan. Work on the above program proceeded with despatch. By the end of 1950, excavation of the Boghra Canal to its farthest extent in the Marja desert was completed. Actual construction of the Kajaki Dam got underway in July 1951, and it was completed by January 1953. The site selected for this dam is at a point where the river flows through a deep narrow canyon in a limestone ridge. Jast above this site the valley widens into a broad alluvial plain, providing an excep-tional combination of a vast reservoir impounded by a very short dam. At full development, the capacity of the lake is nearly 3,000,000 acre-feet (3,500 million cubic meters). The dam is of composite earth and rockfill type with a rolled-filled impervious core. The maximum height of the embankment above the foundation is 94 metres, and the length along the crest is 273 metres. The width of the dam at the base is over 400 metres. The total volume of material placed in the fill is about 3,225,000 cubic metres of which 1,285,000 cubic metres is rock. The dam also provides for building a hydro-electric plant and installing three turbines and generator units with a total capacity of some 120,000 kilowatts. This plant will be built in the future when markets and demand have developed for power of this magnitude. The amount of land which has been farmed in the valley within the recent past is not known, but it is estimated that perhaps 350,000 jereebs (one jereeb is 1/2 of an acre) may be in crops in any one year. By the construction of the Kajaki Dam not only will
