Bhumibol Dam

 

The Office of National Water Resources (ONWR) reported that four major dams in Thailand's Chao Phraya basin are now over 95% full. Despite concerns, these high levels do not currently pose a flood risk as rainfall in upper Thailand is expected to decrease this week. According to ONWR, key dams Bhumibol, Sirikit, Kwae Noi Bamrung Dan, and Pa Sak Jolasid have reached 95%, 97%, 101%, and 99% capacity, respectively.

 

The Chao Phraya Dam in Chainat province is releasing water at 2,000 cubic metres per second, maintaining river levels in Nakhon Sawan and Pathum Thani safely below the riverbanks. The ONWR clarified that rainfall reduction results from the monsoon trough's southward shift over the lower Central region, East, and upper South. Rainfall in upper Thailand is anticipated to lessen from November 3 to 7.

 

While major dams nationwide are at 87% of total storage, holding about 70.144 billion cubic metres, some areas are experiencing drought conditions. In response, the ONWR has initiated measures like installing water pumps to divert water from Phra Roj Creek to Sa Nong Pha Reservoir. This effort aims to supply tap water to Ban Nong Pham village in Ubon Ratchathani, ensuring relief for 135 affected households, reported The Nation.

 

Looking forward, authorities are monitoring weather patterns closely to manage water resources effectively. Preventive measures will remain in place to ensure safety and mitigate the potential impacts of any future heavy rainfall. The ONWR continues to coordinate with local agencies to address both water scarcity and flood management as necessary.

 

Key Takeaways

 

• Four major dams in the Chao Phraya basin are over 95% full but not currently a flood risk.
• Rainfall is expected to reduce from November 3 to 7 due to monsoon shifts.
• Some areas face drought, with measures in place to alleviate the situation.

I always hate when reading this type of news. It usually means just the opposite and to prepare for the worst. 95% capacity is quite full. 1 or 2 good storms will raise that level to overflowing. 

Also, flooding in major cities will still occur during storms. If will only be quicker to drain if there are places for the water to go other than in the streets. 

Friend of mine has just been flooded out in Don Meung area, as has all of her neighbours, from rising river and canal levels.

Yeah, we have a friend in a similar situation.

 

Very heavy rain on Sunday night filled up Khlong Rangsit and it couldn't drain to the river (high tide).
