Dried-up Mekong River inflicts 450 million baht loss to Chiang Rai; Haze remains critical

BANGKOK, 28 March 2013 (NNT) – Drought in the North has dried up the Mekong River and stalled as many as 20 cargo ships in Chiang Rai, while the haze situation in the province remains critical.


With the ships unable to further their journey along the now-shallow Mekong River, as much as 450 million baht of economic losses has been inflicted upon Chiang Rai province.

In the meantime, Chiang Rai city municipal workers have been using firetruck hoses to spray water into the air in downtown areas, in hopes of forcing dust particles in the air onto the ground and alleviating health effects on the public. The attempt was in response to the municipality's finding that 39-265 micrograms per cubic meter of micro particles under 10 microns in diameter were present in the air. The reading was considered to be at a level that endangered the public.

Wanchai Chongsutthanamani, the mayor of Chiang Rai City municipality, distributed dust masks to locals and tourists in Chiang Rai, as well as students at various schools.

The Department of Pollution Control has found that at present, readings in the northern region were the worst in Mae Sai district, followed by Mueang Chiang Rai, Mueang Mae Hong Son, Mueang Nan and Mueang Phrae districts.

Clearly you haven’t done your homework. This is a normal phenomenon this time of year and neither strange nor unusual. The smoke will be with us until we get a heavy sustained downpour and there is nothing in the forecast as yet. Strange, would be to have no smoke around this time.

I guess I haven't. The smoke even reached this point yesterday. You should know...

I could just suck it up and go anyway..

But only since farmers try to have an additional harvest and and using extremely high quantities of water therefor...

spray water (a few meters) in the air, now that is a thai invention to stop not only global warming but also air pollution

Not an ounce, or gram, of brains, do they really think that spraying water into the air is going to make any noticeable difference, if brains were dynamite, these fools wouldn't have enough to make a spark. Wasting water, when there's a drought, you really have to shake your head at the stupidity of it all.

Looks like you are taking the scenic route.smile.png Sorry the conditions aren't better for mountain views.sad.png

The reason the Mekong is dried up is because there are numerous dams siphoning all the water off upstream in China, came down that stretch of Mekong recently and even the small and light(but long) river canal boats scraped the bottom a couple of times.

There were water makers from 5-10 years ago and these show the Mekong at about 5 metres higher than what it is today.

Water volume wise theres less than 5 metres depth left in many areas so doesn't that make it less than half the original water flow rate.

I would guess those 5-10 year water (markers?) were showing the river at its highest during the rainy season and not during the dry season. I don’t know but I would also guess some of the dams have been around at least that long as well. Again I am guessing the math for calculating “original water flow rate” and comparing it to present day flow rates is a bit more complicated than that.

@Village Farang, these pictures will explain more clearly, we're definitely not talking seasonal variation because you can see from the markings on the rocks there are large irregular none returning dips(new dams?). Locals told me that most of the drop was about 5 years ago and its definitely not a rainy season thing thats for sure and the fisherman confirm that anyway. (Dont know the timeline for the dams and how that fits btw)

I don’t know, but when the river is in full flow, the lovely rocks I love to take pictures of are nowhere to be found and there is nothing but water from bank to bank, and quite boring to look at. If those rocks are submerged every year I am not sure how reliable they are as markers of river doom. I am not denying the human pressure on the river just the reliability of river rocks for making any kind of observation.

The Chinese dams up-river are relatively newly built. Last I heard, they had built 3 of 8. It's debatable how much up-river dams affect water levels downstream, and is also predicated on how much those dams are diverting and releasing. My guess is they're diverting water for their own use, and not releasing water until they feel they have to - due to dams filling up - which they're probably not doing now, due to dry season. In sum, the people building and controlling the dams are the ones with the most effect on how much water gets downstream. The Mekong River Commission has as its members: Thailand, Vietnam, Cambodia, Laos and Burma. Notably, China, by far the biggest manipulator of the Mekong, is not a signatory. So, although China has mega influence on the river and the countries/people/nature downstream, it is not bound by anything the little countries decide.

The first victims of unusually low water are the natural components such as fish. Right alongside are the little people who try to eke out a living along the river, and those, further afield, using its water. None of those things are a concern for China, which is only looking out for its own interests.

I'll be traveling to Chiang Rai in a week. I was just wondering about the smog.How serious is the situation?Should I bring a dust mask with me? Goggles and eyedrops? siamiam

Chances are it will be worse by the time you arrive but no one can be sure. We had a brief respite after recent thunderstorms, where PM10 readings dropped below hazardous. Now it is back over 120 but not yet anywhere near the 200’s we had a while back.

I guess it depends on how sensitive you are and what you will be doing. It wouldn’t hurt to bring a mask and eyedrops, I suppose.

Always when i plan a trip somewhere something strange happens. Well maybe the dust is cleared in a week,

Reminds me of a letter I saw in the San Francisco Enquirer, decades ago. A couple would travel, looking for sunny weather, but everywhere they went, it would rain. They decided to rent out their services: Any place that needed rain,could simply hire them to come visit ....voila - rain.

If the Chinese dams are hydroelectric, then they have to release enough water to run the generators. (Turbines) That's a significant amount of water.

Selfish management of a dam would be to store it full of water for the dry season for irrigation and power generation. Depending on terrain, they might be able to run water through the turbines at the bottom of the dam where there's sufficient pressure, and still capture it for irrigation. Otherwise they'd need to take water from a higher level to get it to flow into irrigation ditches.

One would release a lot of water just before the rainy season for flood control, then release as much as needed thereafter to keep a high but steady river flow below the dam, averaging out the affects of rain.

Then just before the end of the rainy season, one would again shut of all water except that going through the turbines, to fill the dam for the dry season use.

A good dam is a very handy thing to have but it should dam a river that flows into the ocean on the dam owner's own soil. Or, it should be jointly owned and managed. I can't imagine China sharing anything with anyone.

It could well be that the water level would be lower without the dams after this long drought. The Mekong flows trough mountaineous terrain in China, there is little agriculture, in particular not during the winter. Looks like this, the pic is from the Xiaowan dam.

Here are all the Mekong dams

You can see the drainage area widens considerably South of Jinghong dam and that's about were the river enters the tropics with supposedly more rainfall. It failed so far this year. Jinghong sells a lot of electricity to Thailand, and it can only be sold when the water is running. Thailand didn't have to build coal-fired plants or other polluters, good.

Very interesting map, thanks for posting that. It shows the watershed which flows through China, but it's the section packed with dams. It doesn't show the upper part of the watershed which comes out of the mighty Himalayas. Water doesn't necessarily fall in greater quantity in lower latitudes. Plus, the terrain shown in the dam photo, above, doesn't soak up rainwater near as well as healthy rain forests one would expect in more temperate zones further south.

Maybe I'm a hopeless tree hugger, but it's a bit sad to think that the Mekong was one of the last great rivers which was undammed - until a few years ago, and now it looks destined to be heavily dammed top and bottom. If the amount of investment in dams would have been focused on solar, both PV and passive, the benefits would be greater, and the destruction to environment would have been avoided.

Solar is not just some PV panels put up on a house roof. It is much more, and advances are happening weekly. Another way to source the power of a river are river flow generators. Only a few exist (all in western countries), but one or two non-intrusive floating generators, could power a small town. As usual, Asians will play catch-up, following western leaders in such innovations. Maybe there's hope for subsequent generations, if they get some incentives to think innovatively.

The upper part is all on the Tibetan Plateau for 2,000 km. Actually a long way from the Himalayas. That's a desert with 100 to 300 mm of precipitation per year, there are no trees to hug. I like lakes, and can see nothing but advantages in reservoires. You might argue that some species of fish can't wander anymore, but what they get in return is a lot more volume of water to thrive in, no droughts anymore that killed whole stocks, etc. It's not destruction of the environment, it's adding a beautiful and useful feature we and the biosphere profit from.
