The Japanese Moon orbiter could not detect any:

Maybe some of those comets which come into the inner Sol system
would be better for obtaining water. A lot of them apparently come
through and we don't even know about them except when SOHO sees
them plunging into the Sun.

Perhaps it is our duty to rescue them and keep all that water and other
volatiles from going to waste. Otherwise it is a long haul to the Kuiper
Belt and an even bigger one to the Oort Cloud.
Though there are all those little icy moons around Jupiter and Saturn
and there may be some dead comets in the Main Planetoid Belt or NEOs
masquerading as planetoids.

But how much lunar water is there really?
