In May 1976, implementing the central government's policy on merging provincial and district administrative units, the three provinces of Quang Binh, Quang Tri, Thua Thien Hue and Vinh Linh area merged into Binh Tri Thien province. After merging into the province, on March 5, 1977, Binh Tri Thien Provincial Party Committee issued Resolution No. 02 on merging districts in the province, two districts of Trieu Phong and Hai Lang into Trieu Hai district. This period marked memorable milestones in water control, irrigation system development, expansion of irrigation canals, laying the foundation for the agricultural development of Hai Lang district until now.
From earth and water to go up
After 3 years of coming out of the brutal war, which left extremely serious consequences, to build the homeland, in agricultural production, the main task of Hai Lang people at that time was to actively reclaim and restore land, expand the cultivated area, improve the fields, and at the same time focus on building technical facilities to serve the intensive cultivation of wet rice. Considering irrigation as the leading measure, promoting the irrigation movement in the whole region.

In particular, with the attention of the central government and the province, and the support and assistance of the people of Binh Tri Thien province, the Nam Thach Han irrigation project was started from March 1978 to June 1979 and put into operation, providing irrigation water for many communes of Hai Lang, with an average of 7,000 - 7,500 hectares of rice fields per year in 1984-1985. In addition, the district invested 14 million VND with 1.5 million working days of cooperatives to build 68 medium and small irrigation works for water irrigation.
In the hilly area, 5 medium-sized reservoirs and a number of small reservoirs with a capacity of 11 million m3 of water have been built and formed, including those in Hai Chanh, Hai Son, Hai Lam, Hai Phu communes... Thanks to the additional irrigation water source and the promotion of intensive farming, rice productivity has increased significantly.
In 1981, there were 17 cooperatives in Hai Lang that intensively cultivated rice with an area of 2,000 hectares, increasing the productivity from 50 tons/ha/year to 82 tons/ha/year. There were 3 cooperatives that achieved a productivity of over 70 tons/ha/year. In 1982, there were 23 cooperatives that achieved a productivity of over 50 tons/ha/year, 4 cooperatives achieved over 75 tons/ha/year - leading in rice productivity in the whole province, including Long Hung Cooperative (Hai Phu) which became the leading flag of Binh Tri Thien province in agricultural development.
It is worth noting that by 1983, the total rice output of the whole district reached over 62,100 tons, the average yield on the two-crop fields was 51.04 quintals/ha, Long Hung Cooperative alone reached over 100 quintals/ha. In 1984, the food output of the whole district reached 62,540 tons, this was the year Trieu Hai district achieved the highest output since the merger.
Irrigation system is increasingly improved
In the process of developing agricultural production, Hai Lang district always focuses on maintaining, repairing and expanding the irrigation system to ensure timely and effective irrigation. Statistics show that in 2024, the total irrigated area of annual crops in the district is 18,304.64 hectares, of which the total irrigated rice area is over 13,600 hectares.
Of the 13,600 hectares of irrigated rice, farmers use natural water to irrigate 4,617.14 hectares, use electric pumps to irrigate over 9,000 hectares and use oil pumps to irrigate 73 hectares. The localities with larger irrigated areas compared to the communes in the district are: Hai Phong (2,410.27 hectares), Hai Duong (2,112.8 hectares), Hai Dinh (1,870.82 hectares), Hai Hung (1,824.5 hectares), Hai Ba (1,136.2 hectares)...
Currently, the total length of canals in Hai Lang district is nearly 360 km, of which 178.78 km have been solidified, reaching a rate of nearly 50%. Of these, the rate of solidified canals in some communes is quite high such as Hai Phu (92.08%), Hai Lam (85.07%), Hai Que (68.38%), Hai Ba (66.49%)...
In addition to the water source from the self-flowing irrigation system, to be ready to pump water for rice when the crop season begins as well as proactively prevent flooding in low-lying areas, Hai Lang district has also arranged a system of irrigation pumping stations, drainage pumping stations and combined irrigation pumping stations.
The district currently has 55 irrigation pumping stations with a total designed flow of 51,800 m3 /h; 5 drainage pumping stations with a total designed flow of 28,300 m3 /h; 26 combined irrigation pumping stations with a total designed irrigation flow of 45,700 m3 /h, and a total designed drainage flow of 45,700 m3 /h. The localities with many pumping stations for irrigation and drainage include the communes of Hai Phong (10), Hai Chanh (8), Hai Dinh (7), Hai Hung (7)...
Hai Lang district has also brought 26 existing dams and reservoirs in the area to participate in supplying water for agricultural production with a total designed capacity of 16.635 million m3 of water, distributed in the communes: Hai Chanh, Hai Son, Hai Truong, Hai Lam, Hai Thuong, Hai Dinh, Hai Phu... Taking advantage of water sources from lakes: Kieu Ngu (Hai Phu), Tram Khang (Hai Truong), Khe Che (Dien Sanh town); dams: Ho Phan (Hai Thuong), Bau Suu (Hai Lam), Truong Xuan, Tram Vung (Hai Truong), Tan Trung, Ruong Cay (Hai Chanh); Tram Tra Loc (Hai Hung)... to "bring water to the fields", especially during dry weather.
Thanks to these efforts, Hai Lang district is currently one of the leading localities in rice production in Quang Tri province with a total rice cultivation area of over 13,600 hectares for the whole year (2024). The average yield of the whole district is the highest ever, reaching 64.67 quintals/ha. Paddy output is 88,188.4 tons. Production value per unit area is 126 million VND/ha.
