(a) Channel cut through Bar.
(&) Strong Shamal. This wind helps to decrease the depth of water in the
river and adjoining marshes : a south wind has the opposite effect.
(c) Rise in Euphrates.
(d) Dredged.
(e) Corresponding fall in Euphrates between Nov. 16 and 20.
Note .—On Nov. 7 the minimum depth on the lake was 2 ft., and hellams
could load to 2 ft. 1 in. The rise on that date was said to be curious, as there
was no corresponding rise in the gauge readings at Nasiriyeh, though between
Oct. 27 and Nov. 4 there had been a rise of 2| in. at Nasiriyeh. (The rise in
the Hammar on Nov. 7 may have been due to Tigris water.) After Nov. 20 the
Euphrates had begun to rise slowly.

The full control of the Euphrates, both for prevention of excessive
floods and for irrigation, must depend on a system of barrage and
escape near the head of its delta.
Provision has further to be made for the water diverted by the
escape. The storage of flood-water is necessary for the development
of Irak, as water is needed for the crops in the summer months of
low supply, when the amount actually in the rivers is not nearly
enough for the thorough irrigation of the country. The heavy irri
gation of Upper Mesopotamia would increase the need of Irak for
great quantities of stored water. If another Power held and irrigated
Upper Mesopotamia an agreement would be necessary as to the
division of the low supply : for the whole of the low supply of the
Euphrates, and much of that of the Tigris, could be cut off from
Irak by irrigation works farther N.
In 1911 Sir William Willcocks mentioned a point below Fellujeh,
near the head of the Abu Ghoreib Canal, as a suitable site for a
