The Ban Mong Reservoir Project was approved in 2009 with the task of providing irrigation water for 18,858 hectares along the Hieu River, including 4,551 hectares with gravity irrigation and the remainder with pumped irrigation; supplying approximately 22 ^m³ /s of water to the Ca River during the dry season; combining power generation with irrigation with an installed capacity of 45 MW; creating a water source for industry, domestic use, and livestock farming; aquaculture and environmental improvement; and partially reducing flooding downstream of the Hieu River.

Regarding the construction component, it includes the Ban Mong reservoir with a capacity of 224.78 million ^m³ and a 45MW hydroelectric power plant with an annual electricity output of 168 million kWh, and 8 pumping stations for drawing water downstream from the Hieu River.

The project commenced construction in 2010; however, due to funding difficulties, the progress had to be postponed beyond 2011 according to Government Directive No. 1792/CT-TTg dated October 15, 2011. Changes in land clearance policies rendered the approved investment amount from 2009 unsuitable. The Ministry of Agriculture and Rural Development (now the Ministry of Agriculture and Environment) reported this to the Prime Minister, who approved the phased investment using additional funds from the Ministry's contingency fund for the 2017-2020 period.

The Ban Mong reservoir is the first irrigation project to research and apply fly ash, a waste product of thermal power plants, to conventional concrete. In fact, the project consumed approximately 22,000 tons of fly ash, replacing about 30% of the cement used. This not only limited environmental impact but also accelerated construction progress and reduced investment costs by approximately 85 billion VND.

During the implementation of phase 1 of the project, the investors and relevant units fully complied with all procedures and formalities; the construction process was inspected by the State Inspection Council, which also reviewed the investor's acceptance of the work.

Land clearance work has been actively carried out by the People's Committees of Nghe An and Thanh Hoa provinces and local authorities at all levels. They regularly hold press conferences and dialogues with people in the project area to share and understand the policies, so that people proactively relocate and hand over parts of the land for the completion of each project item.

The Ministry of Agriculture and Environment has proactively coordinated and repeatedly worked directly with the Secretaries and Chairmen of the People's Committees of the provinces and relevant departments and agencies to resolve difficulties and obstacles.

To date, the entire headworks complex (including the main dam, auxiliary dam, spillway, deep discharge culvert combined with sand discharge, hydropower plant, and water intake culvert), with Project Management Board 1 as the investor, has been basically completed. The quality of the works meets technical requirements, conforms to applicable regulations and standards, and the approved design documents. Eight pumping stations drawing water from the Hieu River, with the Department of Agriculture and Rural Development of Nghe An province as the investor, have been completed, ensuring irrigation water supply for 3,098 hectares.

Land clearance work carried out by Nghe An and Thanh Hoa provinces has basically met the construction schedule; specifically, the reservoir area has been handed over up to elevation +71.86m, while the remaining area from elevation +(71.86÷76.40)m is being actively implemented by the two localities and will be completed in the near future.

The decision to put the Ban Mong reservoir headworks into operation and initially fill the reservoir to an elevation of +71.86m during the celebration of the 14th National Congress of the Party is consistent with the current practical conditions of the project, contributing to the early realization of the project's effectiveness and serving as an important prerequisite for the implementation and completion of the Ban Mong project phase 2 (self-flowing canal system), in order to maximize the efficient use of investment capital.
