"A view of Machai Branch canal at RD 71,000"

Introduction:
Machai canal is the left branch of upper Swat canal. The upper Swat canal was completed in 1914 for diverting a discharge of 68.5 m/s from Swat River at Amandara Head works to irrigate about 123434 hectors of land. Upper Swat canal is bifurcated into two branches at Dargai just down stream of tailrace canal of existing Dargai Power house. The canal flowing to the left is called Machai Branch Canal and the one flowing to the right is called the Abazai branch canal.

Power Potential on Machai Branch:
There are 19 sites on the Machai branch canal where falls have been designed for a uniform slope of the canal. The height of these falls varies in the range of 1.2m to 3.65m thereby resulting in the power potential at each fall. The indicated on individual fall thus ranges from 685 kW to 1726 kW. These potential sites are located between RD 240ft and RD 74025ft. A metaled petrol road leads along the length of this canal. There are pockets of population along the canal with basic infrastructure facilities available.
