I expect you're being downvoted because agricultural irrigation is the primary use of water, not residential water use. Residential water use makes up a relatively paltry fraction of total use compared to agricultural.

How much Lake Tahoe water (or feed water) is used for agriculture?

[gremlinsinc]

Can't speak for tahoe, but here in Utah, I read that total residential water use accounts for about 2% of the total water use of the state, and individual households it's something like 0.02% ... so really it's like comparing an ounce of piss to the ocean.

Alfalfa farms (of which the governor is an alfalfa farmer) are the worse culprits as it's a water heavy plant, and we're also a top exporter of alfalfa to Asia, so essentially Asia's buying our water from us via alfalfa.. there's plenty of other corporate/industrial culprits, but farms are a huge one here..

I'm specifically asking about Tahoe. Down in the valley below, California uses a LOT of water for agriculture, no question. But I'm not sure ag-use is an issue for Tahoe water.

I ask because it's a high alpine lake surrounded by mountains. It has no significant water outflow. I'm not sure there's a path for water from the lake's watershed into agricultural land. Water is lost from the lake to evaporation in enormous amounts and to local uses in much smaller but probably still significant amounts, and that might be about it.

But OP argues that overpopulation leads to increased water usage. Farming takes more water as more people it has to feed.

The statement was a pretty obvious insertion of humor to lighten the mood. I'll eat the downvotes because I don't want to be serious in a world that believes in punishing people for trying to have a sense of humor. :P
