Living in Utah, water is a huge concern for the rate of growth, even in the Salt Lake area where I am. We need a few solid winters to gain some ground back (especially in the Colorado where there is already a large dependence)
In regards to Entrada, DMK has made it much more playable from what I have heard. Millers greens are too zone oriented. I play one of his other designs, Thanksgiving Point, regularly. If you aren't in the right "zone" it is a near impossible two putt. Although DMK has some severe features, from his designs I've played, they seem much more fair. Miller seems to employ the "if you miss this small target, you get screwed" philosophy.
Hope to play Entrada soon so I can compare.
