Does this include the suburbs of Las Vegas? A quick google search gives a report that the whole state of Nevada as a whole has increased their water use (edit: at least for domestic usage). This is in line with most of the population moving out of city centers as people moved into the suburbs that has happened for the last few decades.[0]

Anyway, the fact that the water use of the state as a whole has increased throws out any suggestion that "here, this one segment of the state has decreased their usage" as if that is a serious argument against the rise of water consumption being an issue.

[0] It's a report with data until 1995 but lucky for us it compares levels with 1970 and it did increase significantly EDIT: sorry, figure 1-3

Can't say about the 1970s, but there's a chart in this article showing that total water usage for southern Nevada has indeed decreased since 2002.

According to that graph 2020 usage is almost identical to 2003. So the only significant drop happened between 2002 and 2003. Not to nitpick, just to emphasize that the missing data from 1970 to 2002 could contain numerous large changes too.
