THAILAND, 11th September 2018, (NNT) - Much of Thailand will have a break from rainfall tomorrow (12th), but elsewhere, its expected that as many as 28 provinces will experience continuing precipitation. 

The 28 provinces are Mae Hong Son, Chiang Rai, Chiang Mai, Lamphun, Lampang, Tak, Chaiyaphum, Nakhon Ratchasima, Khon Kaen, Maha Sarakham, Roi Et, Mukdahan, Amnat Charoen, Ubon Ratchathani, Prachinburi, Chanthaburi, Trat, Kanchanaburi, Uthai Thani, Nakhon Sawan, Lopburi, Saraburi, Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Prakan, Samut Sakhon and the capital Bangkok. 

Currently there are also six major reservoirs where the water level is still more than 80% of the dam's capacity. 

In Sakon Nakhon, water held in Nam Oun Dam is at 547 million cubic meters, which is 105% of its capacity. Meanwhile, the inflow and outflow rates of the dam have decreased. Officials are planning to adjust the water release rate to accommodate the draining process in the area behind the reservoir. 

In Phetchaburi, Kaeng Krachan Dam’s water storage is now measured at 721 million cubic meters, 102% of its capacity. The level is still 24 centimeters higher than the spillway. 

The water content of Vajiralongkorn Dam in Kanchanaburi Province is at 8.4 billion cubic meters at the time of this report - 95% of its capacity. Meanwhile, officials have indicated that Srinagarind Dam is holding 16.2 billion cubic meters, which transposes to 92% of its capacity. Both dams in the province have reported a decreased outflow rate. 

On the other hand in Nakhon Nayok, Khun Dan Prakan Chon Dam’s water storage is now at 191 million cubic meters, which is 86% of its capacity. Finally in Prachinburi, the water in Naruebodindrachinta Reservoir is recorded at 262 million cubic meters, which is 89% of its capacity. The management of both dams is expected to further release water in anticipation of the upcoming precipitation.

Dam rainy season . . . they seem to happen every year, these days ?

A few of the reservoirs will be in drought condition by the end of the rainy season! unless it rains more ?

Reckon I could be a valid employee of the weather bureau ?

They do twaddle out some nonsense ? 

It´s raining in Bangkok this morning.

Is it my imagination, or is the wet seasom longer and wetter this year ??

Still much more wetness to come in the next few months I personally love it although I do feel for the people getting flooded.

Not in Buriram it isn't. We are still waiting for it to start.

I think so in Bangkok. It was raining regularly from June. 

 

If you think June - October is not far off half a year of pretty regular rain. 

Actually I was just thinking yesterday that this year's "rainy" season is no where near what it has been in other years. Either that or they've done a fantastic job at mitigating the flood problems in Pattaya because there has been hardly any news (or video) of the massive floods that usually cause such chaos in the city.

When we have heavy rains here there is a spot where the water from the car port roof meets the main roof and shoots out into the soi and the rain gutters are overflowing as they can't handle the amount coming off the rest of the roof (which isn't very large and the gutters/drain pipes are clear so there isn't any blockage).
I've only had that water stream off the roof once this year. The rest of the time the rain has been very light and (usually) not long lasting.

And it was just 3 years ago that they were asking farmers to not plant a second (rice) crop because the water levels were so low they were almost at a critical level.

It also seems odd how the rains seem to skip around certain provinces. I rarely see Sa Kaeo mentioned (and I'm told by people that live there that they never have problems with the land flooding, which I find a bit hard to believe). 

Even this warning (in the OP), it mentions Chanthaburi and Trat, but not Rayong or Chon Buri.

It mentions Bangkok, but not Chachoengsao.
It mentions Ubon Ratchathani and Prachinburi, but not the 3 provinces between those 2 (Sisaket, Surin and Buriram). It also skips Sa Kaeo even though the provinces to the south (Chanthaburi) and west (Prachinburi) are mentioned.

Almost like the rains know where the provincial boundaries are and skirt around some of them !

Mathematically speaking, how can you accommodate water in a dam exceeding 100% - or did I miss something during my heydays at school?

Definitely your imagination. It's been shorter and drier here . . . and that is Thailand . . . not the Sahara.

Sorry I haven't time to read it, K, but it sure gets a 'like' from me, for presentation alone!

Click on link above, levels in this area way down on previous years so far, rainy season hasn't bought the volumes of water we usually see.

It's been pissing down since march, after the diabolical ice age receded. Even the decent weather has forsaken Thailand.

We are still awaiting the last two the goons promised us so we won't hold our breath this time either up here

I live in rural Khampaeng Phet next to the Mae Wong national park and most years my fish pond is at least 2/3 full at this time of the year. In reality it is almost empty (it holds about 500,000 litres when it is full) and the last time it was full was during the big floods of 2011, 7 years ago.

Well there is a design capacity which theoretically should mean 100% and an ultimate holding capacity which could be 100 to 112% + of the design capacity.

 

That's the factual stuff anyway which of course would be way above the water mangement's heads so the Thai's base their dam capacity status reports on the the following, much simpler observations.

 

 

80% Full   - the reservoir looks pretty dark to me sitting in my car

100% Full -  It looks a bit more then last weeks 80%

110% Full  - Hell its nearer the top of that thingy stopping the water 

120% Full - I can see the water flowing over that thingy sitting in my car 20 kms away.

Here in Kalasin we have had rain for almost every day for over two months now.

Your imagination, in Rayong,  we are way below normal

Ours are much much larger then yours but up here in the NE same story.  Lowest they have been at this time of the year for the last 5 years

We're halfway twix town and airport and dry as a bone.

Living in SE Rayong, our pond is at least a meter lower than it was at this time the last two years

The water is all down here in Prachinburi and Nakon Nayok.

 

From whence it is headed to northeastern Bangkok, Chahchengsao and Samut Sokhon.

Airport in Kalasin? We live about 20 km northeast of Kalasin town.

Err, no. Buriram. Since about 16:30 the heavens opened and made me out to be a fake news generator...........Might get some rice this year after all.

Same here. Less than a day after I posted and we got a massive rainstorm in Pattaya last night. I didn't bother getting out of bed and turning on the lights to see if the gutters were overflowing though (from the sounds of the rain on the roof, I was sure that they were).

But the way things have been going, that could be it for the rest of the "rainy" season ! Better stop the outflow on those dams soon or in a couple of months everyone will be crying about not having any water !

 

(Instead of "feast or famine" it always seems to be "flood or drought" around here !)

We had a heavy downpour for about 20 minutes yesterday afternoon, a bit of steady rain for a couple of hours later but nothing for the last 15 hours.

 

My pond is rain fed so unless we get a couple of weeks of solid heavy rain it will useless this year.

That is the problem, the dams are used for 2 purposes, 1 storing water for farmers, 2 preventing floods.

 

They want them both good and by doing so increase risks for failing at both.

 

So either you protect the farmers and others from flooding and they might not have enough water from farming but always dry feet (just let out more water keep the dams low ect) or you keep the dams high accept flooding but will have enough water for farming.

 

By trying to do both they often fail at both. Their choice but i see why things are often going wrong here.. nothing to do with incompetence alone.. but more with trying to pursue 2 goals at once and by doing so risking to fail at both.

The  whole year has been  wetter than last year and the previous 4-5 years which has seen some major  droughts.
