Wouldn't it be a hoot if GPS somehow caused it to rise?

I'm sorry, but this makes no sense to me. I was never good at science, but land rising because of a lack of water underneath it doesn't make sense. And the mountains rising for the same reason makes even less.
Water has substance right? If water is underneath something else of substance, like the earth, and the water goes away then the earth will lower because of gravity. Right? When a sponge loses water it shrinks. Right? Seriously, someone set me straight with this.
Know what I think? I think there are pranksters out there raising those stations just enough to freak pepole out. That's what I think.

So California is utilized to much water. That lack of water is leading to physical changes in the Earth. California is allowing millions of illegal aliens into their state. The millions of illegal are utilized more water, which will cause more physical changes to the earth. Therefore
Illegal Allen's = Climate Change

The earth crust is very flexible, the water is/was in the ground not underneath it.
In this case it's the weight of the water that weighs down the crust of earth, when that weight of water is gone the flexibility of the earth crust will make it rise and the magma underneath the crust will push it up.
I'm just surprised it haven't caused any earthquakes as that seems to be a lot of movement in an already tense earthquake area.
Rising mountains dried out Central Asia, Stanford scientists say
The uplift of two mountain ranges in Central Asia beginning 30 million years ago expanded the Gobi Desert and set Central Asia on its path to extreme aridity, a Stanford study suggests.
THE ANDES
The Andes is the longest mountain range on land. It was formed along the western margin of South America, where two tectonic plates (rocky plates that make up the Earth’s crust) collided. The mountains are still rising by about 10 cm (4 in) every century.
One might think that all this precipitation and glaciation would grind down these mountains faster than tectonic plates can collide to push them up. Yet St. Elias is the steepest mountain belt in the world, rising from sea level to more than 5,500 meters in just 10 kilometers. (To compare, the peaks in the Himalayas rise from a base that’s already 4,600 meters above sea level. From that baseline, Everest is “just” 4,300 meters high. St. Elias is also among the world’s fastest growing ranges, rising 3 to 4 millimeters per year.
Mountain Ranges Rise Dramatically Faster Than Expected

Summary:
Two new studies by a University of Rochester researcher show that mountain ranges rise to their height in as little as two million years -- several times faster than geologists have always thought. Each of the findings came from two pioneering methods of measuring ancient mountain elevations, and the results are in tight agreement.
Both studies yielded the same results: between 10 million and 7 million years ago, the Andes shot up.
To their surprise, researchers have discovered that the GPS network has also been recording an entirely different phenomenon: the massive drying of the landscape caused by the drought that has intensified over much of the region since last year.
Geophysicist Adrian Borsa of the Scripps Institution of Oceanography and his colleagues report in this week's Science that, based on the GPS measurements, the loss of water from lakes, streams, snowpack, and groundwater totals some 240 billion metric tons—equivalent, they say, to a four-inch-deep layer of water covering the entire western U.S. from the Rockies to the Pacific.

The principle behind the new measurements is simple. The weight of surface water and groundwater deforms Earth's elastic crust, much as a sleeper's body deforms a mattress. Remove the water, and the crust rebounds.
