| Khe Ngang Dam can only store water for one spring rice crop, the summer-autumn crop is exhausted. To ensure rice irrigation when the reservoir does not have enough water, Thanh Lam Agricultural Service Cooperative had to use an additional Son Linh 1 electric pump to pump water from Lam River to supplement the rice acreage.

The water regulating valve system from the reservoir to the iron pipe has been severely damaged for a long time. It is impossible to open the valve to increase the amount of irrigation water, or close the valve when the water is full. Currently, the water source is flowing freely from the reservoir to the fields. In the photo: The water regulating valve system is damaged. Photo: Van Truong |
