According to the 2025 spring crop plan, the whole province will plant 189,000 hectares of various crops. To ensure water sources for people to plant on time, irrigation works operators are actively coordinating with localities to implement measures to provide water sources for the production season to achieve high efficiency.
In the 2025 spring crop, Nong Cong Irrigation Branch - Song Chu One Member Co., Ltd. plans to supply water for more than 6,800 hectares of crops in Nong Cong district. To proactively source irrigation water for production, the branch has regularly maintained key irrigation works, operated pumping stations; mobilized staff and workers to dredge the canal system of pumping stations, irrigation canals for communes and towns to sow, irrigate and protect against cold for spring rice. Mr. Tran Van Hanh, Director of Nong Cong Irrigation Branch, said: Based on the crop varieties and the 2025 spring crop planting schedule of Nong Cong district, the branch determined the amount of water required for spring crop production to be about more than 28 million m3. Therefore, from the beginning of the production season, the branch has proactively planned irrigation and drought prevention for production periods. At the same time, coordinated with Song Chu One Member Co., Ltd. to reasonably operate irrigation water on the Muc and Chu river systems. Along with that, assign technical team members to go down to the clusters to coordinate operations in each region and commune, resolving bottlenecks on level 1 and level 2 canals. The branch implements a rotational irrigation plan to raise the water head to transport water faster and further, ensuring that irrigation schedules cover the entire area at the end of the irrigation canals.
According to the forecast of the Irrigation Department, the flow in the spring crop of 2025 on rivers and streams will gradually decrease to a level lower than the average of many years as well as the same period in 2024 from 5 - 10%. In the province, there are still 42/86 reservoirs on the list of damaged and unsafe reservoirs before the 2024 flood season, with no funding allocated for repair or only temporary repairs to serve production. In addition, the impact of climate change is unpredictable, extreme weather phenomena causing production losses can occur at any time such as drought, flood, pests, affecting irrigation and drainage work in the spring crop. The coastal estuary area is strongly affected by tides, saline intrusion in the coastal estuary area is at the average level of many years, and is likely to be affected by salinity.
Based on the actual water resources of reservoirs, the assessment of weather and hydrological trends, the area at risk of water shortage, drought and saltwater intrusion in the spring of 2025 is about 13,300ha - 17,200ha. In which, the large dam area with an area likely to experience water shortage and drought is from 6,300 - 7,700ha, mainly concentrated in the tail of the canal systems taking water from Cua Dat Lake (Bai Thuong system, North Chu River - South Ma River system), Song Muc Lake, Yen My Lake located in the districts of Tho Xuan, Thieu Hoa, Dong Son, Trieu Son, Yen Dinh, Nong Cong, Nghi Son town, Thanh Hoa city,... The coastal plain area and the area affected by saltwater intrusion are from 3,200 - 4,300ha, mainly in the districts, towns and cities in the coastal area and Thanh Hoa city in the South Chu River, North Ma River. This is the area where pumping stations take water from the downstream of Ma River, Len River, Hoat River, De Canal, Yen River... Irrigation areas on the banks of Ma River, Chu River, Buoi River, Cau Chay River with an area likely to be affected by water shortage and drought from 1,400 - 1,900ha, mainly concentrated in Vinh Loc, Thieu Hoa, Yen Dinh, Thach Thanh, Nong Cong, Cam Thuy districts. Irrigation areas using lakes, dams, small irrigation works with an area likely to be affected by water shortage and drought from 2,400 - 3,300ha, mainly concentrated in mountainous areas, reservoirs under construction and lakes with water levels below the dead water level.
Ms. Nguyen Thi Anh Nga, Deputy Head of Thanh Hoa Irrigation Sub-Department, said: Faced with the above situation, the sub-department regularly coordinates with localities in the province, units exploiting irrigation works to promptly inspect and repair machinery, equipment, incidents, and damage to the works to promptly and proactively support irrigation for the 2025 spring crop production. Along with that, mobilize forces to dredge water intakes of pumping stations, repair machinery and equipment of irrigation pumping stations, prepare materials to extend suction pipes when the water level drops, especially for irrigation pumping stations on river banks. Maintain the drought-resistant field pumps that have been installed in previous years, plan to install additional field pumps, take advantage of all water sources to pump and pump water to ensure smooth flow from the source to the field, and apply advanced water-saving irrigation techniques. Irrigation construction companies based on the actual situation decided to build temporary dams to retain water on Cau Chay, Mao Khe, Buoi rivers and large drainage canal systems... to store water for irrigation in the fields.
