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.
Agra, once the capital of the Mughal Empire during the 16th and early 18th centuries, is one and a half hours by express train from New Delhi.
The garden is irrigated by the overflowing of canals.
Thus the quarters near the canals received a proper supply of water and could be used for growing flower-plants which would not hide the general view, while the distant quarters got a smaller supply of water meant for tall trees.
