The term "Tributary" of a river means any surface channel whether in continuous or intermittent flow and by whatever name called, whose waters in the natural course would fall into that river, e.g. a tributary, a torrent, a natural drainage, an artificial drainage, a nadi, a nallah, a nai, a khad, a cho. The term also includes any sub-tributary or branch or subsidiary channel, by whatever name called, whose waters, in the natural course, would directly or otherwise flow into that surface channel.
The term "The Indus," "The Jhelum," "The Chenab," "The Ravi," "The Beas" or "The Sutlej" means the named river (including Connecting Lakes, if any) and all its Tributaries : Provided however that
1. none of the rivers named above shall be deemed to be a Tributary;
2. The Chenab shall be deemed to include the river Panjnad; and
3. the river Chandra and the river Bhaga shall be deemed to be Tributaries of The Chenab.
The term "Main" added after Indus, Jhelum, Chenab, Sutlej, Beas or Ravi means the main stem of the named river excluding its Tributaries, but including all channels and creeks of the main stem of that river and such Connecting Lakes as form part of the main stem itself. The Jhelum Main shall be deemed to extend up to Verinag, and the Chenab Main up to the confluence of the river Chandra and the river Bhaga.
The term "Eastern Rivers" means The Sutlej, The Beas and The Ravi taken together.
The term 'Western Rivers" means The Indus, The Jhelum and The Chenab taken together.
The term "the Rivers" means all the rivers, The Sutlej, The Beas, The Ravi, The Indus, The Jelum and The Chenab.

but the term does not include Agricultural Use or use for the generation of hydro-electric power.

Any act of withdrawal therefrom; or
Any man-made obstruction to their flow which causes a change in the volume (within the practical range of measurement) of the daily flow of the water : Provided however that an obstruction which involves only an insignificant and incidental change in the volume of the daily now, for example, fluctuations due to afflux caused by bridge piers or a temporary by-pass, etc., shall not be deemed to be an interference with the waters.

Provisions Regarding Eastern Rivers

All the waters of the Eastern Rivers shall be available for the unrestricted use of India, except as otherwise expressly provided in this Article.
Except for Domestic Use and Non-Consumptive Use, Pakistan shall be under an obligation to let flow, and shall not permit any interference with, the waters of the Sutlej Main and the Ravi Main in the reaches where these rivers flow in Pakistan and have not yet finally crossed into Pakistan. The Points of final crossing are the following : (a) near the new Hasta Bund upstream of Suleimanke in the case of the Sutlej Main, and (b) about one and a half miles upstream of the syphon for the B-R-B-D Link in the case of the Ravi Main.

Provisions Regarding Eastern Rivers and Western Rivers

Pakistan shall use its best endeavours to construct and bring into operation, with due regard to expedition and economy, that part of a system of works which will accomplish the replacement, from the Western Rivers and other sources, of water supplies for irrigation canals in Pakistan which, on 15th August 1947, were dependent on water supplies from the Eastern Rivers .
Each Party agrees that any Non-Consumptive Use made by it shall be so made as not to materially change, on account of such use, the flow in any channel to the prejudice of the uses on that channel by the other Party under the provisions of this Treaty. In executing any scheme of flood protection or flood control each Party will avoid, as far as practicable, any material damage to the other Party, and any such scheme carried out by India on the Wejern Rivers shall not involve any use of water or any storage in addition to that provided under Article III.
Nothing in this Treaty shall be construed as having the effect of preventing either Party from undertaking schemes of drainage, river training, conservation of soil against erosion and dredging, or from removal of stones, gravel or sand from the beds of the Rivers : Provided that
1. in executing any of the schemes mentioned above, each Party will avoid, as far as practicable, any material damage to the other Party;
2. any such scheme carried out by India on the Western Rivers shall not involve any use of water or any storage in addition to that provided under Article III;
3. except as provided in Paragraph (5) and Article VII(l)(b), India shall not take any action to increase the catchment area, beyond the area on the Effective Date, of any natural or artificial drainage or drain which crosses into Pakistan, and shall not undertake such construction or remodelling of any drainage or drain which so crosses or falls into a drainage or drain which so crosses as might cause material damage in Pakistan or entail the construction of a new drain or enlargement of an existing drainage or drain in Pakistan; and
4. should Pakistan desire to increase the catchment area, beyond the area on the Effective Date, of any natural or artificial drainage or drain, which receives drainage waters from India, or, except in an emergency, to pour any waters into it in excess of the quantities received by it as on the Effective Date, Pakistan shall, before undertaking any work for these purposes, increase the capacity of that drainage or drain to the extent necessary so as not to impair its efficacy for dealing with drainage waters received from India as on the Effective Date.
Pakistan shall maintain in good order its portions of the drainages mentioned below with capacities not less than the capacities as on the Effective Date
1. Hudiara Drain
2. Kasur Nala
3. Salimshah Drain
4. Fazilka Drain.
If India finds it necessary that any of the drainages mentioned in Paragraph (4) should be deepened or widened in Pakistan, Pakistan agrees to undertake to do so as a work of public interest, provided India agrees to pay the cost of the deepening or widening.
Each Party will use its best endeavours to maintain the natural channels of the Rivers, as on the Effective Date, in such condition as will avoid, as far as practicable, any obstruction to the flow in these channels likely to cause material damage to the other Party.
Neither Party will take any action which would have the effect of diverting the Ravi Main between Madhopur and Lahore, or the Sutlej Main between Harike and Suleimanke, from its natural channel between high banks.
The use of the natural channels of the Rivers for the discharge of flood or other excess waters shall be free and not subject to limitation by either Party, and neither Party shall have any claim against the other in respect of any damage caused by such use. Each Party agrees to communicate to the other Party, as far in advance as practicable, any information it may have in regard to such extraordinary discharges of water from reservoirs and flood flows as may affect the other Party.
Each Party declares its intention to operate its storage dams, barrages and irrigation canals in such manner, consistent with the normal operations of its hydraulic systems, as to avoid, as far as feasible, material damage to the other Party.
Each Party declares its intention to prevent, as far as practicable, undue pollution of the waters of the Rivers which might affect adversely uses similar in nature to those to which the waters were put on the Effective Date, and agrees to take all reasonable measures to ensure that, before any sewage or industrial waste is allowed to flow into the Rivers, it will be treated, where necessary, in such manner as not materiallv to affect those uses : Provided that the criterion of reasonableness shall be the customary practice in similar situations on the Rivers.
The Parties agree to adopt, as far as feasible, appropriate measures for the recovery, and restoration to owners, of timber and other property floated or floating down the Rivers, subject to appropriate charges being paid by the owners.
The use of water for industrial purposes under Articles 11(2), 11(3) and HIM shall not exceed
1. in the case of an industrial process known on the Effective Date, such quantum of use as was customary in that process on the Effective Date;
2. in the case of an industrial process not known on the Effective Date : (i) such quantum of use as was customary on the Effective Date in similar or in any way comparable industrial processes; or (ii) if there was no industrial process on the Effective Date similar or in any way comparable to the new process, such quantum of use as would not have a substantially adverse effect on the other Party.
Such part of any water withdrawn for Domestic Use under the provisions of Articles 11(3) and 111(2) as is subsequently applied to Agricultural Use shall be accounted for as part of the Agricultural Use specified in Annexure B and Annexure C respectively; each Party will use its best endeavours to return to the same river (directly or through one of its Tributaries) all water withdrawn therefrom for industrial purposes and not consumed either in the industrial processes for which it was withdrawn or in some other Domestic Use.
In the event that either Party should develop a use of the waters of the Rivers which is not in accordance with the provisions of this Treaty, that Party shall not acquire by reason of such use any right, by prescription or otherwise, to a continuance of such use.
Except as otherwise required by the express provisions of this Treaty, nothing in this Treaty shall be construed as affecting existing territorial rights over the waters of any of the Rivers or the bod& ar,banks thereofi or as affecting existing property rights under municipal law over such waters or beds or banks.

In consideration of the fact that the purpose of part of the system of works referred to in Article IV(1) is the replacement, from the Western Rivers and other sources, of water supplies for irrigation canals in Pakistan which, on 15th August 1947, were dependent on water supplies from the Eastern Rivers, India agrees to make a fixed contribution of Pounds Sterling 62,060,000 towards the costs of these works. The amount in Pounds Sterling of this contribution shall remain unchanged irrespective of any alteration in the par value of any currency.

If, at any time prior to 31st March 1965, Pakistan should represent to the Bank that, because of,the outbreak of large-scale international hostilities arising out of causes beyond the control of Pakistan, it is unable to obtain from abroad the materials and equipment necessary for the completion, by 31st March 1973, of that part of the system of works referred to in Article IVU) which relates to the replacement referred to therein, (hereinafter referred to as the replacement element") and if, after consideration of this representation in consultation with India, the Bank is of the opinion that

these hostilities are on a scale of which the consequence is that Pakistan is unable to obtain in time such materials and equipment as must be procured from abroad for the completion, by 31st March 1973, of the replacement element, and
since the Effective Date, Pakistan has taken all reasonable steps to obtain the said materials and equipment and, with such resources of materials and equipment as have been available to Pakistan both from within Pakistan and from abroad, has carried forward the construction of the replacement element with due diligence and all reasonable expedition,

the Bank shall immediately notify each of the Parties accordingly. The Parties undertake, without prejudice to the provisions of Article XII (3) and (4), that, on being so notified, they will forthwith consult together and enlist the good offices of the'Bank in their consultation, with a view to reaching mutual agreement as to whether or not, in the light of all the circumstances then prevailing, any modifications of the provisions of this Treaty are appropriate and advisable and, if so, the nature and the extent of the modifications.

ANNEXURE A-EXCHANGE OF NOTES BETWEEN GOVERNMENT OF INDIA AND GOVERNMENT OF PAKISTAN

I. Note dated 19th September 1960, from the High Commnissioner for India in Pakistan, Karachi, to the Minister for Foreign Affairs and Commonwealth Relations, Government of Pakistan.

19th September, 1960

I have been instructed by my Government to communicate to you the following :

"The Government of India agrees that, on the ratification of the Indus Waters Treaty 1960, the Inter-Dominion Agreement on the Canal Water Dispute signed at New Delhi on 4th May 1948 (of which a copy is annexed hereto) and the rights and obligations of either party thereto claimed under, or arising out of, that Agreement shall be without effect as from Ist April 1960.

The position of the Government of India stated above and Your Excellency's Note of to-day's date stating the position of the Government of Pakistan on this question will form part of Annexure A to the Indus Waters Treaty 1960."

Accept, Excellency, the renewed assurance of my highest consideration.

A dispute has arisen between the East and West Punjab Governments regarding the supply by East Punjab of water to the Central Bari Doab and the Depalpur canals in West Punjab. The contention of the East Punjab Government is that under the Punjab Partition (Apportionment of Assets and Liabilities) Order, 1947, and the Arbitral Award the proprietary rights in the waters of the rivers in East Punjab vest wholly in the East Punjab Government and that the West Punjab Government cannot claim any share of these waters as a right. The West Punjab Government disputes this contention, its view being that the point has conclusively been decided in its favour by implication by the Arbitral Award and that in accordance with international law and equity, West Punjab has a right to the waters of the East Punjab rivers.
The East Punjab Government has revived the flow of water into these canals on certain conditions of which two are disputed by West Punjab. One, which arises out of the contention in paragraph 1, is the right to the levy of seigniorage charges for water and the other is the question of the capital cost of the Madhavpurl Head Works and carrier channels to be taken into account.
The East and West Punjab Governments are anxious that this question should be settled in a spirit of goodwill and friendship. Without prejudice to its legal rights in the matter the East Punjab Government has assured the West Punjab Government that it has no intention suddenly to withhold water from West Punjab without giving it time to tap alternative sources. The West Punjab Government on its part recognise the natural anxiety of the East Punjab Government to discharge the obligation to develop areas where water is scarce and which were under-developed in relation to parts of West Punjab.
Apart, therefore, from the question of law involved, the Governments are anxious to approach the problem in a practical spirit on the basis of the East Punjab Government progressively diminishingits supply to these canals in order to give reasonable time to enable the West Punjab Government to tap alternative sources.
The West Punjab Government has agreed to deposit immediately in the Reserve Bank such ad hoc sum as may be specified by the Prime Minister of India. Out of this sum that Government agrees to the immediate transfer to East Punjab Government of sums over which there is no dispute.
After an examination by each party of the legal issues, of the method of estimating the cost of water to be supplied by the East Punjab Government and of the technical survey of water resources and the means of using them for supply to these canals, the two Governments agree that further meetings between their representatives should take place.
The Dominion Governments of India and Pakistan accept the above terms and express the hope that a friendly solution will be reached.

After an examination by each party of the legal issues, of the method of estimating the cost of water to be supplied by the East Punjab Government and of the technical survey of water resources and the means of using them for supply to these canals, the two Governments agree that further meetings between their representatives should take place.
The Dominion Governments of India and Pakistan accept the above terms and express the hope that a friendly solution will be reached.

PART 2-Distribution of the Waters of The Ravi
Subject to the provisions of Paragraph 20 and to the payment by Pakistan, by due date, of the amounts to be specified under the provisions of Paragraph 48, India agrees to continue the supply of water to the C.B.D.C., during the Transition Period, in accordance with the provisions of Paragraphs 7 to 19. The balance of the waters of The Ravi, after India has made the deliveries specified in these Paragraphs or the releases specified in Paragraph 20, shall be available for unrestricted use by India.
India will deliver supplies to the C.B.D.C. throughout rabi and during April 1-10 and September 21-30 in kharif (dates as at the points of delivery, no time-lag being allowed from Madhopur to these points), at the points noted in Column (3) of Table A below, according to indents to be placed by Pakistan, up to the maximum quantity noted against each point in
(a) The supply available in the Ravi Main, at Madhopur above, after deducting the actual withdrawal (the deduction being limited to a maximum of 120 cusecs during April 1-10 and September 21-30 and to nil cusecs during rabi) for the Kashmir (Basantpur) Canal, will be taken as the 'gross supply available': Provided that any withdrawal from The Ravi upstream of Madhopur by a new canal constructed after the Effective Date with a capacity of more than 10 cusecs will be accounted for in working out the supply available in the Ravi Main at Madhopur Above. (b) From the'gross supply available'as determined in (a) above, the escapages, if any, from the Tpper Bari Doab Canal into The Ravi will be deducted to get the 'net supply available'. India will use its best endeavours to limit these escapages to the minimum necessary for operational requirements. (c) The'net supply available'as determined in (b) above, limited to a daily ceiling of 6,800 cusecs during April 1-10 and 21st September to 15th October and of 5,770 cusecs during 16th October to 3 Ist March, will be taken as the 'distributable supply'.
If the 'distributable supply' falls below 6,8OrO cusecs during April 1-10 or 21st September to 15th October, the aggregate deliveries to the C.B.D.C. may be reduced to 34.7 per cent of the 'distributable supply'. If the'distributable supply'falls below 5,770 cusees during 16th October to 31st March, the aggregate deliveries to the C.B.D.C. may be reduced to 41 per cent of the'distributable suppy.
If in any year after the Rasul-Qadirabad and the Qadirabad Balloki Links are ready to operate, the average discharge for a period of five consecutive days during 21st February to 6th April in the Jhelum Main at Rasul Above (including the supply in the tail-race of the Rasul hydro-electric plant) exceeds 20,000 cusecs and the daily discharge is not less than 17,000 cusecs on any of these five days, India may, from a date four days after the expiry of the said period of five days, discontinue deliveries to the C.B.D.C. from that date until 10th April in that year : Provided that, if India should decide to exercise this option, India shall notify Pakistan telegraphically three days in advance of the date proposed for the discontinuance of deliveries.
As soon as the supplies specified in Paragraph 66 are available for reduction of deliveries by India during September 21-30 and rabi, the Commissioners will meet and agree upon suitable modifications in the provisions of this Part of this Annexure. In case the Commissioners are unable to agree, the difference shall be dealt with by a Neutral Expert in accordance with the provisions of Annexure F.
A rotational programme will be followed for the distribution of supplies during 16th October to 31st March; it will be extended, if necessary, for the distribution of supplies during 21st September to 15 October and April 1-10. This programme will be framed and, if necessary, modified by the Chief Engineer, Punjab, India, in such manner as will enable the C.B.D.C. to get the due percentage of the 'distributable supply' during each of the following Water-accounting Periods :
1. 21st September to 15th October.
2. 16th October to 2nd December (rabi sowing period).
3. 3rd December to 12th February (rabi growing period).
4. 13th February to 31st March (rabi maturing period).
5. April 1-10.

In framing, operating and, if necessary, modifying the rotational programme, the Chief Engineer, Punjab, will make every effort to see that, within each of the Water-accounting Periods specified above, the supplies delivered to the C.B.D.C. are spread out over the period as fairly as the prevailing circumstances permit.

any discharge observation made by India whenever it may consider necessary to do so, but not more often than once in two months; or
any joint discharge observation by India and Pakistan which may be undertaken at the request of either Commissioner, but not more often than once in three months; the observation shall be made within a fortnight of the receipt of the request.

India will supply to Pakistan, for each channel specified in Table A, a copy of the discharge table current on the Effective Date and of any revised discharge table prepared thereafter in accordance with (i) or (ii) above.

The supply available from the 'Sutlej Component at Ferozepore' and from the 'Beas Component at Ferozepore' less the withdrawals due to be made by India under the provisions of Paragraphs 21 (b), 22 and 23.
The appropriate 'gross amount', as at Ferozepore, detormined in accordance with Paragraph 22 (b).

(i) the supplies required at Trimmu above to meet the withdrawals of the Haveli and Panjnad Canals (after allowing a time-lag of five days from Trimmu to Panjnad), and

(ii) 7,500 cusecs during Phase I or 10,000 cusecs during Phase II, the deliveries specified in Paragraph 34(e) may be reduced, during March 1-10, 11-20 and 21-31 in that year, by amounts related to Pakistan's ability to replace. For March 1-10, 11-20 and 21-31, these amounts shall be taken as equal to 60 per cent of the 'gross amount' determined as follows :

When the sum of (a) the average discharge at Merala Above (obtained by limiting the daily values to a maximum of 25,000 cusecs during March 1-10, a maximum of 26,000 cusecs during March 11-20 and a maximum of 27,000 cusecs during March 21-31) and (b) the Ravi Component at Balloki Above (total supply at Balloki. Above minus the delivery at U.C.C. tall minus the delivery at M.R. Link outfall minus the delivery into the Ravi Main through B.R.B.D. escapes, the result being limited to a minimum of zero) is less than or equal to the Floor Discharge shown in Column (2) of Table C below, the 'gross amount', as at Ferozepore, shall be zero. When this sum equals or exceeds the Ceiling Discharge shown in Column (3) of Table C, the 'gross amount', as at Ferozepore, shall be the amount shown in Column (4) of Table C. When the sum is between the values shown in the said Columns (2) and (3), the 'gross amount', as at Ferozepore, shall be the proportional intermediate amount.
