They should break down the US numbers by State.
I'm not sure breakdown by state would help, I founded something that says Americans love of beef adds a huge amount as does Italians love of pasta
Water withdrawals in that chart might be misleading but I think USA is high however it is looked at.
OECD wrote:Water withdrawals, or water abstractions, are defined as freshwater taken from ground or surface water sources, either permanently or temporarily, and conveyed to a place of use. If the water is returned to a surface water source, abstraction of the same water by the downstream user is counted again in compiling total abstractions: this may lead to double counting. The data include abstractions for public water supply, irrigation, industrial processes and cooling of electric power plants. Mine water and drainage water are included, whereas water used for hydroelectricity generation is normally excluded. This indicator is measured in m3 per capita (a cubic meter is the equivalent of one thousand 1 litre bottles).

If we look at Fresno & Tulare Counties, the snow melt used to flood the entire area, now to goes straight to the ocean bypassing all the farms. This forced the farmers to pump more ground water which has caused thousands of acres to subside by 3-6ft in places.
The latest move is someone has filed to have the Delta Smelt declared extinct & if that happens we can stop pissing all the fresh water into the ocean.

Zero water for the farmers...but they'll keep releasing water from the reservoirs into the ocean.
SACRAMENTO, Calif. - Today, the Bureau of Reclamation announced an update to the initial Central Valley Project 2021 water supply allocation for municipal and industrial water service and agricultural contractors. Allocation amounts are based on an estimate of water available for delivery to CVP water users and reflects current reservoir storages, precipitation, and snowpack in the Central Valley and Sierra Nevada.
The initial CVP water supply allocation was announced in February. Since then, hydrologic conditions have degraded. The 2021 water year for the Sacramento-San Joaquin River Basin is currently the driest since 1977. Between the April 1 and May 1 forecasts, there was a 685,000 acre-feet reduction in the projected natural flow to the Sacramento, Feather, Yuba, and American rivers.
Due to worsening hydrologic conditions, Reclamation is announcing the following updates to the initial 2021 CVP water supply allocation:
M&I water service contractors—north-of-Delta and south-of-Delta—allocation is reduced from 55% to 25% of historic use, which may be adjusted in accordance with the CVP M&I Shortage Policy.
The 5% allocation for CVP agricultural water service contractors—both north-of-Delta and south-of-Delta—which was previously suspended until further notice, is confirmed at 0%.
There are no updates to other CVP allocations at this time.

Nah, that's why they're building so often on floodplains. Solar panels on the roof powering filtration in the basement.
All planned, coming soon
They've actually built homes on a dry river bed near here. The entire river bed is several hundred feet wide, but usually there's just a 10-20ft trickle in the middle. I've seen that river full from bank to bank & several feet deep, fast enough to move rocks the size of small cars.
Looking forward to the next time it does that....
Doesn't look too bad:
However, the upper area outlined is actually part of the river bed & the other two areas are the flood plain...
Where that freeway crosses the river & curves off to the upper right there has been settling. The road surface is rippled like waves on water. Only about 2-3in, but the curve of the road couple with the ripples makes a vehicle pitch from side to side & front to rear.
It's most disconcerting to people who are unaware of what's going on & a shout of "Earthquake!" has passengers in near panic. Managed to catch out every visitor from the UK so far
I think you are making a strong case for the US to stop taking so much groundwater from boreholes. That is not quite the same as diverting all the rivers to industrial/agricultural use.
The real problem is that much of the western US is a desert. Accept that, and don't grow tomatoes in the desert because they need a shedload of water.

They use wells because the fresh water from the snowmelt is sent from the reservoirs to the ocean, Two years ago the reservoirs held enough water to last for 5-6 years (for domestic & ag use). It's all gone. The central valley was known for huge floods, sometimes it was a lake 300 miles long & 20+ miles wide. If the water wasn't sent to reservoirs & then to the ocean via canals etc, it would STILL flood... and those floods, plus irrigation from the canals meant that farmers didn't have to pump ground water.
This entire problem has been created by out of control environmentalists.
