The reservoirs are in various states of damage with six deemed unsafe for operation, according to the province’s Department of Irrigation.
Phan Công Ngôn, director of the province’s irrigation division, said that his office had checked all 43 reservoirs in the locality, assessed their damage and proposed repairs.
Most of the small-sized reservoirs, built before 1990, have been short of monitoring equipment, poorly constructed, and relatively unsafe for operations.
Besides, several reservoirs have poor or no drainage systems and sluice gates, causing sedimentation, erosion and cracks, he said.
To ensure safety for downstream areas, management of the reservoirs’ operations is also important, especially the large-scale ones, he said.
Some dams are at a high risk of being breached, including Ma Póh, Suối Đỉa-Cây Xoài, Tân Rai, Đạ Tẻ and Đạ Tô Tôn, he added.
Đinh Văn Hoàng, deputy chairman of the Tu Tra Commune’s People’s Committee, said the Suối Đỉa-Cây Xoài reservoir faces a high risk of breach, threatening the lives and property of 117 local households.
The committee has organised many activities to raise people’s awareness about protecting, managing and operating the reservoir, he said.
The province has a total of 219 reservoirs, including seven with a capacity of over 10 million cubic metres, an equal number with a capacity of 3-10 million cubic metres, 79 with a capacity of 0.2-3 million cubic metres, and the rest with capacity by less than 0.2 million cubic metres.
According to the agriculture ministry, 1,150 of more than 6,640 reservoirs nationwide suffering different degrees of damage that need to be repaired in the 2016-22 period.
