Since water shortage occurs in the lower reaches of the river basin on the territory of Uzbekistan
efficient water management in the upstream country will result in mutual benefits. The Papan 
Reservoir in the upstream with a net capacity of 250 Mm
3
allows seasonal flow regulation (Figure 2).
Comparison of the inflow and the outflow curves suggests that only 6% of the total water released 
from the reservoir in high water years is delivered during the summer season and 25% in low
water years. In high water years, the irrigation season normally starts in late June due to heavy spring 
rainfall resulting in high soil moisture reserves. As a result, the farmers from the lower reaches of the 
basin have enough water to grow a second crop and the irrigation season lasts till the second half
of October. In low water years, the irrigation season normally starts in April due to the dry spring and 
low soil moisture reserves. Water allocation for the second crop is restricted and the irrigation season 
ends in the second half of September.
