jg7236,
You're quite right about the water shortage (and its impact on trilogy and other courses.) here is an article to that effect.
http://asia.news.yahoo.com/030610/ap/d7rj1heg0.htmlHere are some passages I pulled from it:
That is what some are wondering since the federal government in April cut the amount of water California can draw from the Colorado River — a rollback that has thrown into question the long-term future of the Coachella Valley, a resort and retirement mecca 110 miles east of Los Angeles.
The bulk of that cut landed on the Coachella Valley. The valley's water agency halted deliveries of Colorado River water to about a dozen golf courses, at least one construction company and the lake built for water skiing amid a housing development.
Dave Twedt, the land development manager for the new Trilogy Golf Club at La Quinta, is looking for water to ensure his greens are not brown when Tiger Woods and other top golfers arrive this fall for the popular Skins Game. The club is one of several spending more than $200,000 each to drill into the aquifer far beneath the course.
The many homes, farms, golf courses and other resorts that already use well water are sucking so much from the ground that the valley floor sinks more than an inch a year in spots — a process that could accelerate if the water agency cannot get more Colorado River water, which is usually poured onto the ground and allowed to soak into the earth to replenish the aquifer.
"Because the club has not been properly forewarned and has not been given a reasonable amount of time to transition to a private water supply, there is a real possibility of incurring catastrophic damages," John Heckenlively, president of The Plantation golf club wrote in an April 30 letter to the water district.
But whether the valley finds more water or not, there will probably be no more projects like Palm Desert's Desert Springs Marriott, where guests ride gondolas to feast on ahi steaks by the edge of a sprawling lake, said Crites, the city councilman.
using less turf on courses, among other things, would no doubt help the situation.
