Good points. The water in the lake will come back. The farmland and the farmers might not, if run out of business due to lack of water.
What was your friend’s response to this letter?
There should be riots ever this. The solution is easy, short term, and has been done before.
Makes more sense in 2014.

Instead of the high speed train we should be building 5-6 of these plants.
Heres some info on desalinization

Carlsbad Cal is building a plant which is slated to open in 2016, 16 years after the proposal was approved by the city. Administrative hearings and court processes in which environmental groups got several bites of the apple trying to shoot it down.
It will suppjy up to 10% of the countys water.
What happens to the salt?
The desalination plant typically uses three kilograms of seawater to produce 1 kilogram of fresh water. The extracted salt dissolves in the excess sea water used in the process to form so-called brine. The brine is returned to the sea where it is diluted again in its natural medium.
Can salt be recovered?
The usual desalination processes do not provide for such recovery. Whereas they concentrate seawater 1.5 times, recovery of salt would require seawater to be concentrated ten times. Under such conditions the first crystals would appear in the brine. This would require a lot of energy and cannot be justified on an economic standpoint. Today whenever a large surface area is available close to a sunny seashore, salt pans, which make use of solar energy, are still the best method of salt production.
