with varying heights of 15–25 m (49–82 ft). To pass the design flood discharge two spillway structures have been built. To release water for irrigation to the canal system low level sluices have been built at the downstream toe of the dam with two control valves of the Howell-Bunger type which function as energy dissipation bypass valves.

The third phase of the project will provide water to
Kandahar City. It will help hundreds of thousands of families to have access to drinking water after it is processed. Meanwhile, three turbines will be installed on the dam. Each of them will produce eight megawatts of power. All the turbines will

In the first phase the rehabilitation works were carried out by Canada during the period from 2009 to 2012 under the project titled "Arghandab
Irrigation Rehabilitation Project" at a cost of nearly $ 44 million US dollars. Desilting and repairs to 77.6 km (48.2 mi) of main canal and about

On completion of the rehabilitation works by raising the height of the dam and related appurtenant works, and the improvements of the canal system, the volume of available water would be increased from 300 million cubic meters to 484 million cubic meters. This would facilitate irrigation to command

The reservoir created by the dam has a storage capacity of 314 MCM. The irrigation system designed to provide irrigation to 30,000 ha (74,000 acres) of land in the
Kandahar province consisted of 77.6 km (48.2 mi) of the main canal and 415 km (258 mi) of branch canals; with

The Dahla Dam is an embankment structure made of earth and rock fill. It is 55 m (180 ft) in height. The length of the dam at the crest is about 535 m (1,755 ft). In the periphery of the dam six saddle dams have been built which together measure 2,040 m (6,690 ft) and

Raising the height of the dam is seen crucial to increasing the volume of available water, which has reduced to around 290 million cubic meters from about 500 million cubic meters water. The rehabilitation work during this phase involved raising the height of the dam by 8 m (26 ft), of

415 km (258 mi) of branch and minor canals, replacement of water valves and erecting gates to improve control over the flow of water supplying to farm fields from the reservoir of the Dahla Dam were carried out.
