It seems that NASA held a press conference earlier today (13th Nov 09) to announce the results of the LCROSS data analysis. And they say there WAS water in the plume sent up by the impact.
This was the story reported on the Wiki article about the mission:
http://en.wikipedia.org/wiki/LCROSS#WaterQuote:
Water
Water was found in the ejecta plume. "We are ecstatic," said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. "Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus holds water." [23]
The impact was not as visually prominent as had been anticipated. Due to data bandwidth issues, the exposures were kept short, which made the plume difficult to see in the images. The lighting was not sufficient to show the plume in the short exposures necessitated by the bandwith. This resulted in the need for image processing to increase clarity.[24]
Apparently the second paragraph is based on comments made at the press conference. The first para comes from NASA's own website report posted today:

The argument that the moon is a dry, desolate place no longer holds water.
Secrets the moon has been holding, for perhaps billions of years, are now being revealed to the delight of scientists and space enthusiasts alike.
NASA today opened a new chapter in our understanding of the moon. Preliminary data from the Lunar CRater Observation and Sensing Satellite, or LCROSS, indicates that the mission successfully uncovered water during the Oct. 9, 2009 impacts into the permanently shadowed region of Cabeus cater near the moon’s south pole.
The impact created by the LCROSS Centaur upper stage rocket created a two-part plume of material from the bottom of the crater. The first part was a high angle plume of vapor and fine dust and the second a lower angle ejecta curtain of heavier material. This material has not seen sunlight in billions of years.
(That's just the start of quite a long and interesting report there)
So the NASA finding confirm the very recent discovery by the Indian space probe. It's official. There IS water on the Moon!
