Jazan Valley Dam drives agricultural and water development for over 50 years
Jazan Valley Dam has regulated floodwaters and supported agriculture for more than five decades, with new projects underway to boost its efficiency and sustainability.
Key Takeaways
AIThe Jazan Valley Dam, established over five decades ago, continues to play a pivotal role in regulating floodwaters and advancing agricultural and water development in the Jazan region. Construction of the dam began in 1967 and it was inaugurated in 1971, making it a key component of the region’s water resource management system.
The dam measures 316 meters in length and 37.80 meters in height, with a storage capacity of 54.2 million cubic meters. Since its inception, it has helped regulate the flow of the Jazan Valley, reduce flood risks, supply irrigation water for farmland, and support groundwater recharge.
Development projects to enhance dam efficiency
The dam facility is currently undergoing several projects aimed at restoring and upgrading its structure, removing sediment from its reservoir, and ensuring ongoing maintenance. The total cost of these projects is approximately SAR 116,524,000, including SAR 15,137,000 for restoration and rehabilitation, SAR 85,302,000 for sediment removal, and SAR 16,085,000 for dam operation and maintenance.
Sediment removal is essential to maintain the reservoir’s storage efficiency, as accumulated sediment affects the capacity of the tanks. Rehabilitation and maintenance efforts also help ensure the dam’s readiness to handle water flows and preserve its infrastructure.
Ongoing environmental and developmental impact
The dam’s impact extends to the environment, with its reservoir promoting plant growth and providing habitats for wildlife and birds, adding ecological and aesthetic value to the area. The dam stands as an early example of water resource management with a developmental vision, transforming seasonal floodwaters into a regulated resource that supports agriculture and local communities.
With ongoing maintenance and rehabilitation, the Jazan Valley Dam remains a cornerstone for agricultural and water development in the region, continuing its positive impact for future generations.
