Water Levels
Water Levels
With all of this recent rain, have the water levels begun to rise?
When does the flow of the Tonle Tap change?
How high do the levels need to raise for the hydro plants to operate as normal?

near the end of the year novemberish there is a thing called the water festival in pp (best to be avoided at all costs) which supposedly celebrates the changing of the flows. look for the dates uself

The levels are looking extremely low:vladimir wrote: ↑Mon May 27, 2019 10:02 amI think you'll find info on levels here:

They are exceptionally low all the way up into Thailand and Laos, but completely not related to the dams built in China that they had to open the last time things were a bit iffy. Looks like either they're not cooperating this time around, or bizarrely nobody downstream has asked the Chinese why the water supply is so low.
My Chinese searching is not good enough to find out if the actual source is dried up versus normal years, or if there a gazillion cubic metres of the stuff sitting in reservoirs in China that somebody forgot to release.

Would that be another conspiracy theory then?Spigzy wrote: ↑Mon Jul 29, 2019 12:20 pmThey are exceptionally low all the way up into Thailand and Laos, but completely not related to the dams built in China that they had to open the last time things were a bit iffy.

People have been blaming the Chinese dams for low water flows in the Mekong system since they were completed over a decade ago, but their effects would be relatively insignificant.
The dams were built in the upper course of the river, close to the source. Discharge, which is measured in cubic metres/sec.. is very low there and would only contribute less than 10% to the volume passing through Phnom Penh.
About 2/3 of the water enters though the banks and bed of the river channel via groundflow, through the soil, and baseflow, through permeable rocks. Baseflow is very slow, taking as long as thousands of years to reach a river. On the other hand, groundflow is seriously affected by seasonal precipitation and subsequent changes to the level of the water table.The rest of the water cones from overland flow, through tributaries or over saturated surfaces during heavy rain.
The most likely explanations for the current low water levels would be an unusually hot and dry spell during the first 4 months of the year, which would have lowered the water table and reduced groundflow, plus the lower than normal precipitation in the first half of the wet season, which would significantly reduce overland flow. The northern part of Cambodia is currently classed as drought affected. The classification of what is called drought varies enormously worldwide, but it essentially means much lower precipitation than usual. Blame the weather; not the Chinese.

People generally classify hydropower as a wonder power but it ain't.
Alot of the time you have reduced or no rain and therefore reduced/no power or you have massive rains which means the turbines have to be turned off or the pressure will break them

That’s a proper reply, thanks for the lessonGilmore wrote: ↑Tue Jul 30, 2019 8:09 amPeople have been blaming the Chinese dams for low water flows in the Mekong system since they were completed over a decade ago, but their effects would be relatively insignificant.

Any source to check water levels at Tonle Sap? To see how it compares to previous years? I think the link above only shows for the Mekong River.

the closest monitoring station to the Tonle Sap Lake is at Prek Kdam, which i think that graft refers to,is on the Mekong River Commission website.
updated every Monday, Currently the water levels on the Tonle Sap Lake are 2.3 mtrs but raising quickly as they can do. i have seen the lake raise over a mtr in a week in the past. This year the levels are approx 3 to4 mtrs below the average and certainly about 4 mts lower than this time last year,

yes 2.3 mtrs yesterday, today it may well be 2.5 mts, that is a measurement taken from where our Queen Tara is moored which is out on the Lake, the highest i have recorded is just over 10 mtrs and lowest is half a mtr ,currently its raising quite quickly, of course the floor of the lake is silt so its a measurement from the current water levels to the silt,the lake is quite flat.it can vary of course as its also effected by tides and winds of some degree. last year i had taken a boat our PBR(gun ) boat from Phnom Penh to Siem Reap,at this time of the year and the levels where approx 6 mtrs (middle of the lake) and also where the Queen Tara was moored, so this year it has a lot of depths to make up:) it varies from year to year
