If anyone has data or live monitoring sites please post here. The more the merrier.

Let's keep everyone informed and keep our feet dry!

 

We're going to need it! Need to get a reading on the water level in the dams, too.

https://www.thaiwater.net/ is worth a look but it can be a bit slow and confusing.

Unfortunately, specific, real-time data on the water levels and discharge rates of all dams in Thailand for today, May 14, 2025, is not readily available in a single, comprehensive source. The information is often spread across various reports and updates from different agencies.

However, based on the available information, we can provide some insights and comparisons with data from last year (2024):

Current Situation (May 14, 2025):

• Major Dams: Thaiwater.net provides some current levels for major dams:
  • Bhumibol Dam: Current level is at 55% of normal capacity (27% usable storage).
  • Sirikit Dam: Current level is at 58% of normal capacity (28% usable storage).
  • Pa Sak Jorasit Dam: Current level is at 21% of normal capacity (21% usable storage). This indicates a significantly lower level compared to the other two major dams.
  • Wachiralongkorn Dam: Current level is at 59% of normal capacity (25% usable storage).
• Chao Phraya River Basin: Reports from early May 2025 indicated a rising water level in the Chao Phraya River in Bangkok due to increased discharge from upstream, with northern runoffs around 1,900 cubic meters per second.  
   
• Overall Reservoir Storage: A report from late April 2025 stated that the total water volume in large-scale reservoirs nationwide was 59% of total capacity, with 39% usable storage. This was noted as being higher than the same period in 2024.
• Mekong River: Water levels at key monitoring stations along the Lower Mekong mainstream, particularly in northern Thailand, reached alarm levels in late August 2024 due to persistent heavy rainfall. Nong Khai station reached flood level. While this was a situation from last year, it highlights the potential for rapid changes in water levels due to rainfall.

Comparison with Last Year (2024):

• A report from late April 2025 mentioned that the overall usable water volume in large-scale reservoirs was higher (by 2,055 MCM) compared to the same period in 2024.
• In late September 2024, there were warnings issued for provinces along the Chao Phraya River due to increased discharge rates from the Chao Phraya Dam, necessitated by heavy rains and runoffs from the North. This led to concerns about potential flooding in low-lying areas.  
   
• In late October 2024, further warnings were issued for downstream provinces of the Chao Phraya Dam due to heavy rainfall in upstream areas, leading to increased discharge rates up to 1,600 cubic meters per second.

High tide at Ko-Kret

 

 

And the Green House

 

 

 

 

High tide at Ko-Kret, not really much to report as yet.

 

 

 

This was high-tide at Ko Kret this morning, definitely a bit of upness, but still well in the green.

 

 

There are big tides coming towards the end of the month https://www.tide-forecast.com/locations/Bangkok-Thailand/tides/latest we shall see if anything significant occurs then.

 

Flood warnings upstream?

High this morning.

 

 

Tonight will be the highest.

 

 

 

High last night, hopefully this is the highest, for now.

 

 

This morning at the Green House.

 

 

I've set up one of our CCTV cameras for a river view, it's not available on the public internet just yet (that's Task B) but I can monitor it from anywhere.

 

A slightly different view but the main features are there 🙂

Dam level update from Gemini.

 

Here's the latest information as of June 12, 2025, or as close as possible:

Current Situation (June 12, 2025):

• Overall Reservoir Storage: As of June 9, 2025 (the most recent comprehensive data available), national reservoir storage had reached 43,246 million cubic meters, accounting for 57% of total capacity. These reservoirs still have the capacity to receive an additional 33,245 million cubic meters (43% of their full capacity). This indicates a healthy overall water situation for the start of the rainy season.

• Major Dams (Chao Phraya River Basin - as of June 9, 2025):

• The four major dams in the Chao Phraya River Basin (Bhumibol, Sirikit, Kwae Noi Bamrung Dan, and Pasak Jolasid) currently store a combined 13,158 million cubic meters, which represents 53%1 of their total capacity. They can still accommodate 11,713 million cubic meters of water.

• Specific percentages for individual dams (as of early June/late May 2025 reports):

• Bhumibol Dam: Around 55-57% of normal capacity (28% usable storage as of latest Thaiwater.net).

• Sirikit Dam: Around 53-58% of normal capacity (23-28% usable storage as of latest Thaiwater.net).

• Pa Sak Jorasit Dam: Around 16% of normal capacity (16% usable storage as of latest Thaiwater.net). This dam consistently shows lower levels compared to the others.

• Wachiralongkorn Dam: Around 55% of normal capacity (21% usable storage as of latest Thaiwater.net).

• Srinagarind Dam: Reported at 72.94% capacity (April 2025 data).

• Bang Lang Dam: Reported at 82.28% capacity (April 2025 data).

• Rajjaprabha Dam: Reported at 62.52% capacity (April 2025 data).

• Chao Phraya River & Discharge Rates:

• Recent continuous rainfall across several regions has increased water inflows.

• The Royal Irrigation Department (RID) has been actively managing discharge rates. As of a recent report (early June 2025), the RID found it necessary to gradually increase the discharge through the Chao Phraya Dam at station C13 (Sapphaya district, Chai Nat province) from2 600 cubic meters per second to 700 cubic meters per second, effective from June 9, 2025. This was due to rising water flow from the North.

• River water levels in northern Thailand's major tributaries remain within normal ranges. For instance, the Ping River near Banphot Phisai District in Nakhon Sawan was about 4 meters below the riverbank, and the Nan River in Chum Saeng District was 6 meters below (as of June 9, 2025).

• The water flow at station C.2 in Mueang Nakhon Sawan District (where the Ping and Nan rivers converge to form the Chao Phraya) measured 710 cubic meters per second, still approximately 7 meters below the riverbank.

• Recent Warnings/Events:

• On May 28, 2025, residents in Ang Thong and Ayutthaya were warned of possible Chao Phraya River overflow due to increased discharge from the Chao Phraya barrage, which had increased its water discharge to 1,000 cubic meters per second. This raised downstream levels by 0.6 to 1.7 meters.

• The Thai Meteorological Department has issued warnings of continued heavy rain in the North due to a passing monsoon trough, raising the risk of flash floods and landslides.

Comparison with Last Year (2024):

• Higher Overall Storage: A significant point is that the total water volume in large-scale and medium-scale reservoirs as of May 25, 2025, was 3,022 MCM higher than in 2024 for all reservoirs, and 2,918 MCM higher for large-scale reservoirs specifically. The Northern region's reservoir volume was also 2,525 MCM (or 23%) higher than in 2024. This indicates a generally better water reserve situation at the start of the rainy season this year.

• Chao Phraya Dam Discharge: Last year, around late September 2024, the Chao Phraya Dam increased its outflow from 1,500 to 2,000 cubic meters per second due to higher water from the North. This was a significantly higher discharge rate compared to the current 700 cubic meters per second. This suggests that while there is an increase in discharge this year, it's not at the same critical levels as late last rainy season.

• Drought Concerns: In early May 2025, the Lam Takhong Dam in Nakhon Ratchasima was reported at its lowest water level in 20 years (9% capacity), highlighting that some regions are still facing drought challenges despite improved overall national storage. Last year, in November 2024, farmers in Korat were warned against a second rice crop due to low dam levels, indicating ongoing regional water stress.

In summary:

As of June 12, 2025, Thailand's major reservoirs appear to be in a better water storage position than at the same time last year, thanks to recent rainfall. The Royal Irrigation Department is actively managing dam discharges, with current increases being implemented in response to northern runoffs, though these rates are generally lower than peak discharge events seen in late 2024. The emphasis is on balancing flood mitigation with ensuring sufficient water for the dry season. However, localized drought concerns persist in some areas, like Nakhon Ratchasima.

For the very latest real-time data, it is always recommended to check the official websites of the Royal Irrigation Department (RID) or Thaiwater.net, as water conditions can change rapidly with weather patterns.

High last night (big tide) nothing to worry about right now.

 

In reaction to this thread 

 

Here is last night's high at Ko Kret, towards to top of the green but nothing to worry about at present.

 

Peak of the current tide cycle will be on Saturday evening.

Here’s a snapshot of Thailand’s dam conditions as of early August 2025, compared with the same date in 2024:

---

Current (≈ August 3–6, 2025)

• Sirikit Dam

  • Storage: over 80% capacity, with only ~1.5 billion m³ free (Bangkok Post)

  • Discharge: maintained at 40 million m³/day (ongoing through ~August 10) (nationthailand)

• Chao Phraya Dam

  • Discharge: reduced to 1,000 m³/s to prevent downstream flooding (nationthailand)

• Bhumibol Dam

  • Storage: around 58% capacity (7.79 billion m³ of water) (nationthailand)

• Other Northern dams (July 2025 data)

  • Mae Ngat Somboon Chon Dam: 67% capacity

  • Mae Kuang Udom Thara Dam: 51% capacity (tiwrmdev.hii.or.th, nationthailand)

---

Same Period in 2024 (Late August 2024)

• Bhumibol Dam: ~45% full

• Sirikit Dam: ~71% full

• Khwae Noi Bamrung Daen Dam: ~38% full

• Pa Sak Jolasid Dam: ~30% full (InterRisk Asia (Thailand) Co., Ltd., ASEAN NOW, Wikipedia)

Comparative Table: 3–6 August 2025 vs. ~26–31 August 2024

Dam / Location	Approx. Date	Storage Level	Discharge Rate
Sirikit Dam	Aug 2025 (early)	> 80%	~40 million m³/day
	Late Aug 2024	~71%	—
Bhumibol Dam	Aug 2025	~58%	—
	Late Aug 2024	~45%	—
Chao Phraya Dam	Aug 2025	—	~1,000 m³/s
Other Northern Dams	Aug 2025	51–67% (varies)	—
	Late Aug 2024	—	—

---

Interpretation

• Significantly higher storage in early August 2025 compared to late August 2024—Sirikit is up from ~71% to over 80%, and Bhumibol rose from ~45% to ~58%.

• Discharge rates in 2025 (Sirikit: 40 M m³/day; Chao Phraya: 1,000 m³/s) reflect active management to create buffer space and mitigate flood risk.

Note on Data Gaps

Unfortunately, there’s no precise day-for-day data (e.g., August 3, 2025 vs. August 3, 2024). The 2025 figures are from early August, while the 2024 data comes from later in the month. Still, the contrast is stark: 2025 saw wetter conditions and fuller reservoirs at this point in the season.

If you'd like, I can keep an eye out for additional dam data or daily auto-updating sources. Just let me know!

Peak tide for this cycle. Not much going on, yet.

Key Insights

• Significant increase in dam storage by mid-August 2025:

  • Sirikit dam rose to 83% (vs ~71% in 2024).

  • Bhumibol storage is substantially higher (~8.7 billion m³ vs ~45% full last year).

• More proactive discharge management in 2025:

  • Sirikit kept discharge at 55 million m³/day to create capacity ahead of heavy rains.

  • Discharge rates for Chao Phraya Dam are comparable but data suggests cautious adjustments.

• Overall water availability is noticeably better in 2025, offering more buffer for the coming dry season.

Ko Kret high last night.

 

 

Crossy floodcam.

 

 

 

I asked chatGPT to do us a graph of the important data, the available data is incomplete but the trend for fill-level and discharge rate is definitely on the up.

 

I'll try to keep it updated as data becomes available.

 

Last night's high at Ko Kret, not really much going on right now.

 

Next big tides are around september 7th.

 

 

Village is definitely damp but well below our worry level at present.

 

Somewhere near last night's high (the EON stream is a bit variable), definitely showing a degree of upness.

 

High last night, nice to see Mr Jetski has a life preserver on board.

 

No data update from the dams at present.

 

 

Definite dampness in the village but nowhere near worry level yet.

 

 

 

 

High last night, stable. For now!

 

 

Bangkok tide for the next couple of weeks.

 

Last night's high, a bit of a jump since the previous night.

 

Watching closely.

 

 

 

And the rise continues, cue the "Jaws" music ...

 

 

Wow! Water everywhere. Let's hope it don't rain.

For us local rain isn't really an issue other than making the garden like a swamp. It's hammered down several times over the last week, and drizzled all night too, no flash-flooding.

 

It's the slow-motion train wreck caused by what fell up-north a few days ago and has now been released from the dams that's the issue. Last time we actually flooded it didn't rain at all during the inundation, lovely sunny days in fact.

 

Really heavy rain in our area near Kuchinarai.

First time in 8 years the rain has flooded the garage.

Good we have 2 doors, let it in 1 door and out the other.

Overcame the water spouts.
