4. Is there any alternative? At least one city in the United States (Tampa Bay) uses desalination.

It's not free or cheap, but it works.

Saudi Arabia has also enlarged its water desalination capacity using high-tech green technology and it produces more than 24 million cubic meters of water per day.

Desalinated water, of course, would have no value to inland resevoirs like the one in Noblesville, Ind unless there was a way to transport the water. In the past, we built the Erie Canal and even the Panama Canal. Plus the energy companies currently use lengthy pipelines to transport oil and gas. As expensive as it would be, it would be possible to desalinate water and transport it inland. Saudi Arabia can do this. If we are going to have permanent climate change, maybe we should consider it. Maybe those in Indianapolis who rely upon the Morse Reservoir, and others who rely upon other reservoirs, should consider it.
