Yes, the only other lake which we passed by (morning of day 2 after summiting Koruna Peak), but did not stay at, was Islet Lake:

- Islet Lake on a beautiful morning.

- Islet Lake.
The other lake which would be accessible with a few hours to spare is The Moat below Citadel Shelf - via a fairly open spur running down from near The Citadel (East Citadel) & a pretty easy bash down to the lake shore, we didn't really find time to do this tho & there was plenty of water in the creek at camp. Citadel Shelf is the obvious flat area at the left of photo.

- The Moat (Madonna Ridge & The Lion behind).
