Not specifically no. It has only filled a few times in the last century as
a result of heavy rains generally associated with La Nina. Wasn't the last
time in the 1970s? I am guessing that SW QLD hasn't had that much but I
don't know how much higher than average is required to get a flow. If you
go here you can fiddle the settings to show if the catchment has had
rainfall higher or lower than average etc.

If you want to see it you will have plenty of time to get ready as it takes
weeks for the water to flow down that far so you will have notice that it is
likely to happen.
