decision and India's interests were sacrificed. Besides, out of 40 years, from 1949
to 1988, there might have been some years of very high and some years of very
low discharges which should have been excluded from determining the average and
the maximum years of occurrence of predominant discharge should have been taken
into account to arrive at a reasonable volume of flow. The earlier agreement and the
MOUs took note of this but the 1996 accord did not.
The Treaty did not consider increasing the Ganga flow at Farakka in future, which
was falling in the lean season, especially from February to April. A comparison of
the actual flows reaching Farakka with those of the schedule of water-sharing at the
barrage from January to May, as per the 1977 agreement, or the MOUs of 1982 and
1985, reveals the facts, as shown in Table 11.1.
The table shows that the actual discharge at Farakka in 1988 and 1997 were far
less than the anticipated flow of 1977 and 1996, as recorded in the agreement and the
Treaty. For instance, the actual flow of 1988, compared to that mentioned in 1977
accord was about 11.5% less in January, 18% less in February, 12% less in March
but 1.50% and 23% more in April and May, respectively. From February to April,
when the demand is highest, the flow reduces. The excess flow in April 1988 was
due to sudden rise in the discharge in the last 10-daily period. Similarly, the actual
flow at Farakka in 1997, compared to the flow, envisaged in the 1996 Treaty, was
