junglechef Posted July 1, 2015 Share Posted July 1, 2015 The levels are supposably quite low at Mae Kuang Dam which supplies the Chiang Mai city. The klongs below it on the East side of San Sai are low while those on the West side that are supplied by Mae Gnat Dam are full. I was at farms yesterday on both sides of this city and there's a huge difference. Link to comment Share on other sites More sharing options...

A lot of aquifers were laid down over ten thousand years or more and some as recent as a 1000 years ago, the problem is we are mining water with no chance of replenishing it for future generations!!! Underground water is not a finite commodity as some may think. Link to comment Share on other sites More sharing options...
MESmith Posted July 1, 2015 Share Posted July 1, 2015 Rice farmers where I live, San Kamphaeng, are flooding their rice fields from boreholes. Every year more boreholes as more & more farmers copy their neighbours. Link to comment Share on other sites More sharing options...
junglechef Posted July 1, 2015 Share Posted July 1, 2015 Another issue for the small local organic farmers (those are one's whom I personally familiar with) is if there's not enough water in the klongs the cost of running pumps isn't cost effective. Even people who are growing veg just for their own family's consumption find it cheaper to buy them at the local market then pay for the additional electricity necessary to pump the water out of their existing wells.

chiang mai Posted July 1, 2015 Share Posted July 1, 2015 There is a klong that runs through our garden in Mae Rim, it sees a flood of water about every ten days, sometimes longer and this is right in the heart of rice fields. I can still get water for the garden from a four metre well and our deeper well, fifteen metres, is still sound, fingers crossed. Have to disagree about the cost of running a pump. a one HP pump uses about 0.75 kwh so the cost to run the pump for one hour is less than 5 baht.

junglechef Posted July 2, 2015 Share Posted July 2, 2015 I'm just repeating what they tell me ("they find it cheaper") as haven't seen a financial breakdown. But for 40 bth (8 hrs x 5 baht) one can buy a lot of veg. Of course there's what season it is and other factor to consider. They do release water from Mae Gnat for the needs of the rice farmers and other factors which I can't exactly figure out. Luckily you, as well as I, get our water from the bigger reservoir. As well as a few klongs that run through my property I have a pond which is fed by one of them as a reserve, a well and of course city water which I combine all for my watering needs. All one has to do is look around to see how much more greener it is over here. Link to comment Share on other sites More sharing options...
chiang mai Posted July 2, 2015 Share Posted July 2, 2015 I was planning to drive up to Mae Ngat to check out water levels, if anyone has any recent pictures they could post you'll save me a trip. Link to comment Share on other sites More sharing options...
kaptainrob Posted July 2, 2015 Share Posted July 2, 2015 I recently came across an old report done on the CM - Lamphun aquifer by German(?) engineers. IIRC, the summary mentioned the then (15 year ago) use was exceeding re-supply (via rainfall) and bores would have to go deeper and deeper with a bottom of ~200m. Currently, bores are relatively shallow at up to 50m and water quality good albeit high in iron and manganese. Going deeper presents difficulties with expense and higher fluoride content.

chiang mai Posted July 2, 2015 Share Posted July 2, 2015 Indeed, I'm surrounded by rice fields and I frequently see the same thing. I was more interested though to see the levels of the reservoir itself, the last time we went up there for lunch was about six months ago and we were shocked by how much the water levels had fallen since our previous visit.

HTT is a very small resevoir, Mae Ngat and Mae Kuang (just behind MaeJo) are the big ones. Mae Kuang Edited July 2, 2015 by MaeJoMTB Link to comment Share on other sites More sharing options...
Sparkles Posted July 2, 2015 Share Posted July 2, 2015 Driving home from the city, alongside the Ping this morning, south of the new mega baht weir it is indeed a dismal sight.There are parts where utilising sand bars you could almost walk across it. Hopefully Dave will be on duty with some photos. Which brings me to the fish farms coupl ekm or 2 further south.I guess they are still pulling fish out of them for sale. Maybe they are sold at local markets or by the side of the road.If so that practice should be terminated until there is an increased flow. Anyone got access to recent water quality readings in the Ping? I would suggest a distinct health hazard is a possibilty Link to comment Share on other sites More sharing options...

What, in Thailand? 55 If you saw what was running down a Pa Daet khlong (and ultimately into the Ping) today you would never ever consume fish farmed downstream. Stinking black gunge with garbage floating on top ... it's a wonder no-one reports this as it must be industrial waste from up near Hangdong road.

It seems to be about the same level very little noticeable change day to day. I didn't realize how shallow it was until the other day there was a fellow out about 40 to 50 feet wading in it and it was only up to his knees. This was on the West side of the river.

CNXBKKMAN Posted July 2, 2015 Share Posted July 2, 2015 I cycled around the reservoir at the back of the 700 Stadium. Basically because the water level is so low and there is a sandy shore. I passed a couple of days ago and the water is even lower. Link to comment Share on other sites More sharing options...

Presumably the more things get concreted over then less water is going to be soaking into the water table. The same should apply for areas of less vegetation where water will evaporate more quickly. One wonders when the love affair for concrete might end. Link to comment Share on other sites More sharing options...
kaptainrob Posted July 3, 2015 Share Posted July 3, 2015 @Sally .... aquifers are mainly fed by underground streams originating in the hills. Rainwater filters down through fissures and porous material and can take many years to find its way into the 'reservoir' below us. Fortunately very little comes from our polluted concrete environment directly above although some shallow bores may have contaminated water from seepage.

Fortunately very little comes from our polluted concrete environment directly above although some shallow bores may have contaminated water from seepage. Of major consideration would be that the zone between the hill watersheds and the urban areas has seen a decimation in the amount of ground cover. (That doesn't count the concrete "ground cover" !!) More evaporation, less damp areas, faster run off due to harder top soil. All these lead to less seepage into the underground water system.

chiangmaiexpat Posted July 3, 2015 Share Posted July 3, 2015 Yes, the water level at HTT is very low and the levels are also quite low in the other bigger reservoirs around CNX. Since we are experiencing unusually hot and dry climate and had little rain this year, it's no surprise. July is also suspiciously dry, so we could be headed for a drought.
