New study reveals remote lakes in Ecuador are not immune to climate change
From Queen’s University
A study of three remote lakes in Ecuador led by Queen’s University researchers has revealed the vulnerability of tropical high mountain lakes to global climate change – the first study of its kind to show this. The data explains how the lakes are changing due to the water warming as the result of climate change.
The results could have far-reaching consequences for Andean water resources as the lakes provide 60 per cent of the drinking water for Cuenca, the third largest city in Ecuador.
“Until recently we knew little about the effects of recent climate changes on tropical high-mountain lakes,” says Neal Michelutti (Biology), lead author and a senior research scientist at Queen’s University’s Paleoecological Environmental Assessment and Research Lab (PEARL). “We saw major changes in the algae consistent with the water warming that indicates changes in the physical structure of the water column.”
Dr. Michelutti and his research team visited three lakes in Cajas National Park. They retrieved water and core samples from the centre of each of the lakes for analysis. The lakes are accessible only by hiking trails and boats are prohibited. There is also no development within the park meaning the lakes are still in pristine condition.
“Andean societies are amongst the most vulnerable when it comes to the impact of climate change,” says Dr. Michelutti. “Warming in the Andes is occurring at a rate nearly twice the global average and it’s already impacting water resources as shown in this research. These changes are also a sign of bigger changes that are coming.”
Dr. Michelutti and his team are planning to return to the region for further research this summer and will be working with lake managers in the area to try to preserve the water.
“We have previously recorded similar types of threshold shifts in polar and temperate regions,” says research team member John Smol (Biology). “These changes are harbingers of processes that will likely affect the food chain and reverberate throughout the ecosystem. We now have data showing that lakes from the Arctic to the Andes, and everywhere in between, are rapidly changing due to our impacts on climate.”

Is there any place on earth that isn’t warming at twice the average?
I’m sure Lake Wobegon is. Everything there is above average.
Twice nothing is nothing.
So we have evidence of Ecuadoran Warming (well they say they do).
And Ecuador is what percentage of the globe to which the term “global Warming” relates ??
It worse than that! I might be warming at 100 or 1000 times the global average rate!
Global average rate = 0
1000 * 0 = 0
Everywhere seems to be warming at twice the global average. Makes you wonder a bit, about how the global average for warming rates is calculated.
Haha!!!! You are so right! “Warming at twice the global average”!
Definition — Boilerplate is any text that is or can be reused in new context or application without being greatly changed from the original.
And, of course, the global average of warming for the last 18 years has been zero. Twice times zero is zero and zero is always zero.
But wait! Perhaps not in the new math of climatology.
Multiple computer runs of multiple computer simulations of global warming have given climatologists a range of potential values for zero — therefore some zeroes can be greater or lesser than other zeroes. Therefore climatologists can endlessly use and reuse the phrase “Warming at twice the global average” when the global average of warming is zero.. The models provide the data about the various potential values of zero and indeed, some of of the computer runs do show warming at twice (or more) the rate of others when the actual warming has been zero.
All very simple. Climatologists have proved that zero can have multiple values! The big surprise is that these various values for zero are all positive. Perhaps that needs intense investigation.

What I’d like too see them come out and discover is locations where the average temperature is cooling, to allow for the greater than average warming in other places.
It is simple, you take the actual warming signal from stations around the globe then calculate the median temperature change. Subtract the median anomaly difference from the actual measurements and divide the anomaly by 2. Then, when measured against the actual anomaly for any given station, the warming signal indicates twice the global average for every measurement used.
Another example of ‘everywhere is warming faster than everywhere else’?
Except Boston!
Yes, but the cold in Boston is caused by Global Warming.
Well, isn’t it a warmer cold?
/grin
Just as you are freezing to death, you suddenly feel hot! Thus, ….
The cold is rotten doncha know.
Well that “warmth” is all in their heads anyway.
The actual Temperature isn’t increasing at any statistically non-zero rate.

Well Ecuador always used to have very pretty postage stamps.
Yep – the observed changes are definitely due to us. These guys wouldn’t have a clue but they’re obliged to attribute the changes to us. For shame.
At least they may have access to renewable, eco-friendly geothermal energy.

makes you laugh, they write – the co2 has an effect on the atmos- but “These volcanoes are pumping out 2,100-degree-hot basalt and scalding hot water” doesn’t.

One possibility is changes in the Evapotranspiration rates from the adjacent Amazon Jungle caused by clearing for farming within the region. Similar to the Kilimanjaro effect.

The lake on the illustration photo is Skelton Lake on North Ellesmere Island in Nunavut, Canada!
Even the photos are changing. That’s unprecedented, but is it sustainable?
And probably taken during the summer. Winter temps in Nunavut are approx. -40 C in the winter
Huh?
The Canadian province of Ecuador?
Geez, I must have missed a map update.
Well the Canuks got tired of owning a big chunk of the Arctic circle, so they started investing in buying up equatorial properties, and some clunkhead misspelled it on the deed, so they ended up with Ecuador, instead of Equator.
Pretty easy to get them confused.
Global Warming radically changes geography.
Given lakes like Lake Titicaca in the Andes are 12,500 ft (around 2 miles) above sea level, how is it possible that CO2 could be causing them to warm at “twice the global average”?
A significant portion of the atmosphere, a significant part of the greenhouse blanket, is below the lake elevation.
(A wasted posting effort by a banned sockpuppet. Comment DELETED. -mod)
According to the Wiki entry, 50% of the atmosphere is below 18,000 ft. Assuming a linear distribution of mass up to 18,000 ft, this means around 30% of the atmosphere is below 12,000ft – so the greenhouse effect at 12,000 ft should be 30% weaker than at sea level.
http://en.wikipedia.org/wiki/Atmosphere_of_Earth
How can a greenhouse effect which is 30% weaker cause warming which is twice as fast as the global average?
(A wasted posting effort by a banned sockpuppet. Comment DELETED. -mod)
“I don’t think 2 miles is a significant part of the atmosphere.”
A really simple way to compute the percentage of atmosphere above and below is compare atmospheric pressure at an altitude to surface pressure. Since surface pressure is roughly 1000mb, then the percentage of the atmosphere above you at some altitude is just the pressure in mb divided by 10.
Pressure Approx. Approx.
Level Altitude Altitude
850 mb 5,000 feet 1,500 m
700 mb 10,000 feet 3,000 m
500 mb 18,000 feet 5,500 m
300 mb 30,000 feet 9,000 m
250 mb 35,000 feet 10,500 m
200 mb 39,000 feet 12,000 m
So at 2 miles, roughly 10,000 feet, 70% of the atmosphere is still above you (and so on).
“There is roughly 10ppm difference between 8-9km and 16-18km.”
Yes, CO2 is indeed “well-mixed” throughout the atmosphere, suggesting that a very large part of the global CO2 (natural and otherwise) has been absorbed and buffered by the oceans, which release it uniformly all over the globe.
icouldnthelpit, the 10ppm difference isn’t the big difference. It might even be 10 ppm difference a 50 or 90 miles, but mass, my friend is very different.
You “think” that over 1/3 of atmospheric mass is not “significant”? Hypoxia becomes a threat at elevations above 12,500′ msl.; why?
2000 feet is above the planetary boundary layer (PBL) below which frictional and other chaotic effects can dominate the weather and climate. Cooler and dryer too. But it’s still in the lower half of the troposphere, with significant impact on weather, not necessarily having any thing to do with co2.
(A wasted posting effort by a banned sockpuppet. Comment DELETED. -mod)
Icouldnthelpit : Although the paper referred to actually deals with 5-25 km profiles , no-one is arguing that the CO2 volume mixing ratio is not almost unchanged with altitude . That is a common chart in most standard textbooks like those of Goody or Salby .
However the number of CO2 molecules per unit volume will drop with altitude according to hydrostatic principles . Also if H2O is a relevant greenhouse gas , then , since its vol ratio drops so quickly with altitude, its contribution to radiative forcing is also lowered – making the assertion that this area is exhibiting more global warming than lowland levels a bit surprising.
I need to check the paper again to see what allowance is made for local solar input.
Whatever, but it still hasn’t been shown that LWIR can heat water. Period.
As the global average temperature has not increased over the last 18 years, what they are in effect saying is that the temperature in the lakes has not changed one iota!
I think they should have gone with 10x as much if thats the case. Really sell it guys!
Living at just 2500 meters , I find the notion that the atmosphere at 3900 meters holds enough heat to have changes in CO2 make any significant difference highly improbable . Even here the diurnal variation is about 20c year around . And atmospheric pressure declines exponentially with altitude .
If there are changes in the algae due to CO2 , they are almost surely due to it being the very building block , in equal measure with H2O , of the algae as of all life .
I agree especially with the last sentence!
Isn’t one of the base assumptions in the sampling of mean monthly temperature changes to determine the global annual temperature anomaly that any changes occur uniformly and simultaneously across the globe?
Would have been nice if they had compared their results with previous studies.
But it’s climate science, so as usual the spin is more important than the science.
They claim the first study of it’s kind (in the article). But seeing someone used a picture of a Canadian Arctic area lake I wonder if they ever went up there in the first place, IE go look for something no body has done, built a story and here comes the $$$$
Why do I think that this study is one that would not have received funding UNLESS the dire consequences of climate change are included?
Funny, as I am posting this I just heard on the radio about a British study that states “we were misinformed about fat in one’s diet”
Is the concentration of CO2 still 400ppm at higher altitudes?
Funny how the temperature drops the higher up you go. Funny how that happens even on high flat plains. Funny how the top of the Grand Canyon is colder than the bottom, even though the bottom receives shade from Canyon walls. Does the concentration of CO2 and water vapour drop dramatically as you ascend from the Canyon floor? Does the sun really warm the atmosphere from the surface up as claimed in the pictures presented to the public on greenhouse gasses?
Oh and if we could remove all “greenhouse” gasses from our atmosphere would the surface temperature drop to that of the moon? Would there be any change in temperature at different altitudes on land if that happened?
The day/night difference would change a lot anyway: see the diurnal temperature difference of dry deserts and compare them with other parts of the globe with huge humidity. Even without clouds in both, the difference in deserts is much larger, as water vapor retains more heat at night. Clouds makes the difference even (much) smaller, as they reflect sunlight up during the day and reflect IR down at night.
I doubt that the difference will approach the moon’s difference, as the warming/cooling there lasts 14 days each and on earth only 12 hours, where the warming/cooling of especially the oceans is much smaller in that time span. The oceans, water vapor and clouds are the main thermostats of the earth…
@ur momisugly wickedwenchfan February 10, 2015 at 5:01 am
The Sunshine heats the earth surface …. and the earth’s surface radiates that “heat” as Infrared Radiation (IR) which the “greenhouse” gasses in the atmosphere absorb and “warm up” …. IF said IR radiation makes contact with them ….. but then those warmed up “greenhouse” gasses immediately beging to radiate that “heat” back into the atmosphere.
But, …. but, …. if any of the other atmospheric gasses (Nitrogen, Oxygen, etc.) make contact with the “hot” earth surface (via action of the wind, etc.) or any of those warmed up “greenhouse” gasses then their said “heat” will be “conducted” directly to those other atmospheric gasses.
So, when you go outside in the “heat of the day” you are actually “feeling” MOSTLY the heat of the Nitrogen and Oxygen and not the heat of the “greenhouse” gasses. And iffen you use a fan to cool yourself down …. it is mostly the Nitrogen and Oxygen that are CONDUCTING the “heat” away from your person.
Thus, iffen there were no “greenhouse” gasses in earth’s atmosphere it would still get just as “hot” during the daytime ……. but would get a lot colder at night time ….. just like it now does in desert areas.
wickedwenchfan,
Water vapor is extremely variable and its maximum in air depends of temperature and pressure, CO2 is simply mixing in all ratios with air, giving it enough time to mix.
Near huge sources and sinks, like in the bottom of valleys and in general in the first few hundred meters over land, you can find hundreds of ppmv extra at night under inversion and less than average during the day (plant respiration and photosynthesis), but once a few hundred meters above the surface you will find near the same levels (+/- 2% of full scale) everywhere up to 24 km height.
Above that height, there is little stirring and the molecules are far from each other, thus having less collisions (Brownian motion), which makes that the heavier molecules like CO2 tend to drop out and the lighter like helium tend to be enriched.
PEARLS of wisdom.
Pearls of wisdom delivered by swine?
I am waiting peer-reviewed research that show the optimum climate for our biosphere. The first question that would naturally flow would be where is our current climate and trend in relation to this finding.
Strangely, nobody seems interested in this vital comparison. Not so strangely, the solutions that are frequently demanded in the most urgent voice, all converge on a socialist worldview: statism, bigger government, higher taxes, less personal liberty, even fewer people. That bigger picture tells me all that I need to know about “climate science”.
“the optimum climate for our biosphere”?
Let’s see: we find living things on Earth in environments ranging from sub-freezing Antarctica to the bottom of the Pacific ocean near boiling thermal vents, an enormous range of temperatures and pressures. Clearly there are as many ‘optimum climates’ as there are organisms.
Which suggests that the notion that the Earth has a single ‘climate’ is a chimera, an abstraction in search of a referent. ‘Climate science’ is essentially the study of an imaginary entity. No wonder its practitioners act like the adherents of a religion.
/Mr Lynn
“Until recently we knew little about the effects of recent climate changes on tropical high-mountain lakes,”
So in reality they little data to go on and less historic data but ‘know ‘ these is ‘ also a sign of bigger changes that are coming’ models plus speculations does not equal data nor proof . Meanwhile they are right in that if you want any more of theses trips they better make sure that their ‘results’ hit the funding honey pot of AGW.
And none of that makes any difference to the reality that despite the claims we are simply not seeing increase in temperature in line with increases in CO2 in the manner they where told .,by settled science, we would .
The actual study may be found at PLOS|One: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0115338#pone.0115338.ref028
I am not challenging the author’s findings, which may be an accurate assessment of relatively recent ecological changes in the region. The study’s basic protocols appear sound and their findings appear defensible. I do wonder, however, if they have successfully excluded potentially confounding factors.
For example, it would be interesting to compare the Cañar meteorological station data (~ 30 km away), which they utilized, to that from the Park Ranger’s weather station at Laguna Toreadora itself, if available. The climate-related conclusions of the study depend upon two factors: a presumed increase in average temperature at these lakes (~ 1.15 C) and a reduction in average windspeed (down to about 5 km/hr). Eyeballing their Figure 2 left me wondering if there was any relationship between temperature, windspeed, and SST over the period studied. That’s important because these factors are presumed to have reduced historical mixing of the lake waters and resulted in thermal stratification, thus promoting measurable changes in the predominent plankton species.
I also note that a paved road is visible in photos of Laguna Toreadora at the official National Park website: http://parque-nacional-cajas.org/weer.html. The authors state that “[t]he lakes are accessible only by hiking trails.” Perhaps the other two lakes sampled were a bit more remote from the Park’s access roads. The authors mention that shore fishing is allowed at Park lakes but there is no data on whether this human activity is on the increase or whether their lakes have any introduced species.
In any event, the first lake to experience a shift in plankton populations was Laguna Toreadora, commencing in the 1960s. [“The Discostella rise first occurs in the highest elevation lake (Laguna Toreadora, 3,920 m asl) beginning in the early 1960s, and latest in the lowest elevation site (Laguna Llaviuco, 3,140 m asl) during the late 1980s.”] Yet that early period there appears to have no correlation to higher temperatures or lower windspeeds, again based upon their Figure 2. As noted above, Laguna Toreadora appears to be one of the more accessible lakes in the Park. Perhaps there is an overlooked correlation with road paving (enhanced human access) and plankton populations?
Thanks for this considered reply to the study. Why would the changes start in 1960s when there was no evidence of “climate change” then? How can they construct a temperature sequence leading to this drastic increase in temperatures at this height if the place is so inaccessible and without stevenson screens? The GISS method of extending temperatures for miles away from a station has been proven to be shall we say “shaky” so really the study is probably based more on assumptions that reality. Good try though and will probably keep the money flowing.
Because that was two (2) years after Keeling “nailed down” the atmospheric CO2 ppm numbers.
Checking the satellite views on Google maps, it looks like Highway 585 is a two lane paved road that passes about 500 meters from Lake Toreadora. There seem to be some paths or perhaps little used unpaved roads leading to various spots on the South Shore. The rest of the region seems relatively free of roads although there is a rather unusual construction a few kilometers West at -2.7983,-79.2797 Lots of small lakes.
Another problem with the study is that they use different sampling densities at different deep. In the most recent layer 1 cm-spacing, in the deeper layer 5 cm, Based on this I can’t see how they can claim that the recent change is “unprecedented” since sampling density in the lower layer is too sparse to detect changes over 20-50 year periods.
Also note that the wind data aren’t measured. They are NCEP/NCAR 600 mb reanalysis data, i e modelled, and I have no idea how reliable reanalysis data are in this part of the World, particularly in complex mountain terrain.
I had assumed the sampling was based on sedimentation rates but will have to look at the paper again. I’ve mostly moved on since this paper — like almost every other paper I’ve examined on climate induced ecological disaster (frogs, polar bears, coral reefs, bird habitat, etc.) — is based upon an assumption that climate is changing the examined habitat/behavior rather than a scientific demonstration linking the two. Typically, that is because there is no data on point so the authors substitute speculation. The press release then ignores the speculative aspect and presents the “findings” as further confirmation of climate doom. One grows weary…

No boats and sampling the middle of the lake? Sure hope they washed their boots, as that seemed to be the problem in the ‘Great Frog Extinction” story.
Problem with drinking water?? A simple sand filter will take out 99.9% of bio materials, less than 4 foot is common in modern waterplants.
Could someone please tell me what a Paleoecological Environmental Assessment and Research Lab really is? Is it similar to a Paleomicroagression Gender Assessment and …?
Tom, Here’s his spiel explaining his function in proving CAGW:
I wonder if the researchers took into account the fact that this area is where high altitude and the South Atlantic Anomaly come together in a perfect storm of solar UV variability. And they’re talking about the effect on algae.
It is true that increased UV can suppress phytoplankton growth rates and would be likely to alter population balances. A few years ago, this paper would have been presented as proof that the ozone hole was worse than we thought.
But plankton isn’t the only thing sensitive to UV radiation. The UV exposure in equatorial regions is naturally greater than at high latitudes (due to the angle of the sun and the effective “depth” of the ozone layer). In addition, for every 1000 feet in altitude the ultraviolet flux increases by about 4 percent. The Canadian researchers started about 3000 miles from the equator and within a few hundred feet of sea level so I hope they took lots of sunscreen.
Check. Climate change never, ever happened before 1960.
Sounds so much like the old acid rain scare that was supposedly destroying lakes world wide. Repackage and repeat.

“There is no development in the park so the lakes are pristine” and “the lakes provide 60 percent of the drinking water for Cuenca, the third largest city in Ecuador”
Hmmm…so, like, doesn’t the initial construction and continuing operation of all that gadgetry that taps into these lakes and moves water in such a volume that it provides the third largest city in Ecuador with 60 percent of its drinking water constitute a sorta, kinda “development”, that just might–just maybe, is all I’m sayin’–make lefty, hive-tool claims that these lakes are “pristine”, a cause for skeptical wonderment–you know, like, along the lines of are we possibly dealin’ here with just another one of your standard-issue, hyped, hive-bozo, agit-prop scare-boogers, beautifully timed to lend good-comrade support to the brazen-hypocrite, carbon-piggie eco-conference to be held, later this year, in Paris? You know, that sort of thing.
“They retrived water and core samples from the center of each of the lakes for analysis” and “boats are prohibited” and “We saw major changes in the algae consistent [WEASEL-WORD ALERT!!!] with the water warming”
I may be engaged in some over-active head-scratching here, but, if no boats are allowed in the park, then how did the guys takin’ the water and core samples from the lake, get to the middle of the lake to take their samples, I’m wonderin’? “Sumpin’s not right here”, my little B. S. Detector is flashin’. Wait!…I’m gettin’ another reading now on my B. S. Detector (this one’s all caps in the original): ASK ‘EM IF, IN THE COURSE OF ALL THE SCIENTIFIC STUDY OF THE LAKES AND MAJOR CONSTRUCTION OF ALL THAT WATER-MOVING WHAT-NOT, SOMEONE DIDN’T TRACK IN ALGAE FROM WARMER, LOWER ALTITUDES THAT WAS ADAPTABLE TO THE CONDITIONS OF THESE HIGHER ALTITUDE LAKES AND HARDIER AND MORE COMPETITIVE THAN THE LAKE’S ORIGINAL ALGAE!!!
Anybody?
‘Cause dey dragged a big kettle all de way up de hill to da pristine lake, then built a fire ‘longside dat dere pristine lake with da logs dey also dragged up da hill to da pristine lake; and done did boiled alllll da water de also dragged up de hill to da pristine lake (causin’ it is a pristine lake in all ya know) and dat dere heat in da boilin’ water did kill all da algeas on de boat dey used to sample da water in da middle of dat dere pristine lake.
Yep. De did all dat. Cause it is a pristine lake, ya know.

Here is your ecological “threshold” tickler.
The lakes being studied here are between 3,000 and 4,000 m above sea level. Bear in mind that at altitude CO2 will be relatively more important than water vapor.
Hey guys!
Don’t know if anyone noticed, but I just got a “shout-out” in HotWhopper’s latest blog-post–some real braggin’ rights there!
You know, I’m beginin’ to get this sneakin’ suspicion that once you get on her good side, HotWhopper is not really the school-marmish scold she wants everyone to think she is, but, rather, that she has a good-fun sense-of-humor, after all. And then some, I’m thinkin’.
dang you got there before me Thanks though, people pressure as usual.
I noted they used a rubber dinghy to get to the middle of the lake. (These must not count as “boats”)
I also noted they blamed El Nino “Second-order fluctuations in temperature bear a strong relationship to El Niño-driven sea surface temperature (SST) anomalies (Fig. 2B), conferring the direct influence of Pacific Ocean inter-annual variability, superposed on the secular recent warming trend. ”
and their last statement ” Given the inevitability of increasing human pressure on lakes regionally, the observation of pronounced ecological restructuring becomes especially sobering.” how is sobering a scientific term? LOL…
OK, has anyone taken the time to check out these lakes on Google Earth? An asphalt highway was built through the valley and the “pristine” Toreadora is all of 400 feet from the road. Has a big parking lot, too. Llaviacu is a mile and some from the highway but has its own side road and facilities. It is also less than ten miles from the center of Cuenca, with 400,000 people and 700,000 including the area surrounding. I wonder when the roads and facilities was built? I think this is an example of poor science. Go here to see more.

In the lake photo, isn’t that a volcanic cinder cone in the middle of the lake basin?
As pointed out above, that photo is not from the Andes. Look here http://post.queensu.ca/~pearl/PNAS2005.htm, where it’s described as, “A typical lake from north-central Ellesmere Island, Nunavut, Canadian High Arctic.” It’s credited to “Bronwyn Keatley, Queen’s University, July 2003”.
Parts of the Ecuadorean Andes appears to be volcanically active with volcanic lakes and calderas too. Obviously just food for thought.

@ur momisugly Jim, I googled that lake there is access to this one houses are built I wonder about the waste water for these pristine lakes (i know you posted the picture as an example but it just makes you wonder how far the warmistas are willing to go)
“Andean societies are amongst the most vulnerable when it comes to the impact of climate change,” Please define vulnerability from climate change. You mean like too much snow? Too many hurricanes? Tornadoes? A growing season?
That’s just the setup for the emotional appeal.
They are the human penguins and polar bears which are helpless creatures. Except when they want to migrate or eat other animals (penguins are predator birds, by the way! Big time!).
You folks have to realize that with Antarctica getting colder, there has to be a lot of places in the world “warming at twice the global average” to make up for it, so it is easy to understand now why the global average has been stagnant for 15 to 20 years, right? Just think how much worse it would have been if Antarctica wasn’t working it’s little heart out trying to balance all that warming!
It sure would be nice to see some of all that research money going into finding ways to mitigate the problem without destroying civilization instead of being wasted on useless research that solves nothing at all accept employing imaginative researchers. If the truth is that the key to saving the world was finding a way to curb carbon dioxide, it seems to me that money spent on these sort of wasted research projects would have been better spent finding that new elusive and practical energy source we need, but no, we have to keep on throwing money down a research rat hole that serves no purpose what so ever.
Hey, the initial CO2 global warming meme originated in the late 70’s/early 80’s as a method to tax the rich and transfer wealth to the poor in a good old world government, we know what’s best, way. We are now at least 35 years later and the scheme continues unabated . . . . follow the money . . . politicians, researchers, NGO’s, doom dayers/sayers, on and on. The weird thing is most of the global warming do-gooders are actually getting in the way of the commerce necessary to improve the well being of all global citizens. Read books like Abundance for a different, and optimistic, view of the future.
water quality is endangered by 1.7C +
IN ANY CASE such lakes must not be used for drinking water supply!
