Problems and Solutions

The major problem addressed in this study is that the existing water supply
condition is inadequate to irrigate the project area, This is due to the temporal
distribution of the runoff and insufficient storage capacity in the system, In other
words, there are high spring runoffs in excess of irrigation needs in the beginning of
the irrigation season. The excess spring runoff cannot be captured for beneficial
use in late season due to lack of storage capacity, The irrigation water shortages
are aggravated by the fact that most of the shortages occur late in the irrigation
season when steady water applications are required to sustain crop growth, Under
the existing condition, the irrigators in the project area tend to apply large
amounts of water to their lands early in the irrigation season in an attempt to
partially offset late season shortage. As a result, excessive application of water is
utilized in the beginning of the irrigation season when the runoff in the streams is
high.

Therefore, according to the consultant, the solution is to increase the use of the
available water sources by providing additional storage facilities in the system and
improving the overall management of the land and water resources, so that
shortages occurring later would be reduced,
