Flood Warnings 2011


Recommended Posts

Also the Mae Kuang res. if far from full, so no reason at all to release water.

Besides, if they do it will join the Ping well south of the city, they might not like it in Lamphun but it is not relevant for the water level in CM

Like I said in a previous post about Dams being released it is all hearsay. I haven't been up to the dams in a while so if they are only half full that is good news.

The guy didn't say which dam it was so who knows? The river is up more than 20cm (to 3.34m) since this thread started this afternoon and continues to rise in Sansai. It's just started to rain again so it's looking a bit like the crunch will come about breakfast time.

Opening the dam at Doi Saket should not effect Chiang Mai City, thats a different flood plain through San Kampang and onto Lamphun.

I have heard that at least one of the Moo Bans, Swirilai 3 has water up to the doors on the San Kampang road, so that cannot be good news.

San Kampang is lower than Chiang Mai.

The criteria to release water from the reservoirs is not how full they are. It's how strong the responsible officer estimates his dam. And that may lay far under 50 % of the capacity of the resorvoir...

Why are the latest river levels on the site below forbidden for me too see. Is this a worrying sign.:o

The info is still there, and updated but you have to tab through different screens.

As there is now a widespread problem (or anticipated problem) they have put several marker stations on one web page (Ping, Wang, Kuang, Pasang etc). They have made an hurly table for today and the next two days

I cannot paste a link as it just has the main web address.

At 11.00pm it was showing Nawarat as being 3.45metres.

They did have this graphic.

It seems that we are only 25cm from the critical, thankfully the rain seems to have held back a bit now....but the stuff from San Sai still has to come down so I am more concerned about how quickly the Ping discharges (and where).....

Looks (thankfully) like my 60cm estimate was wrong yesterday - it's risen a lot in Nong Hoi south of the bridge but still has about 30 cm to go. These pictures are of the area adjacent to the bridge looking east and show that there isn't much leeway there either.

Flooding in Pai according to the television news. Gonzo... Do you have an evacuation plan there?

It was flooding a bit (not there but seen photos on Facebook) but not as bad as in the great floods a few years ago. River level is very high, some light flooding, and of course as to be expected bamboo bridges and those straw hut guest houses right new to the river damaged.

CM seems to be fine now. Yesterday the canal road canal was close to overflowing in the morning - 5 - 10 cm under some bridges - then very low towards the evening - sure looks like the authorities are doing a good job preventing flooding, really, I can only imagine that extremely high level was due to draining a dam somewhere.

That CM flood map posted above was very interesting, thanks a lot for that. Does anyone have historic flood levels in the ping river?

We just bought some land at the very outskirts of the flood zone near HD road. In my estimate we should be OK if we raise the land by 80cm or so, then we should be well above any flooding. We were planning to do this anyway because that's what some of the neighbors in that moo baan had done and we figured there was probably a good reason... ;)
