The canal receives its water from the Jumna River at Okia, about ten miles below Delhi. The weir across the Jumna was the first attempted in Upper India upon a foundation of fine sand; it is about 800-yard long, and rises seven-feet above the summer level of the river.
From Okla the canal follows the high land between the Khari-nadi and the Jumna, and finally joins the Banganga river about 20 miles below Agra. Navigable branches connect the canal with Muttra and Agra.
