No first hand knowledge, but according to SIX you cross the upper reaches of Tianjara Ck (7.9km), an unnamed creek (10.2km) and Rixon Ck (12.3km) from the Braidwood Rd. Water would probably depend on season and when it last rained. The whole trip is only 25km and seems to more or less stay on top of the range, so if you're used to cycling and not carrying camping gear you could probably do it in a couple of hours and with an early start you shouldn't need much water.
At age early 30s, when I regularly used to ride that distance from Caringbah to Milperra for work, I'd considered parking at the dam, riding half way and returning. Half a lifetime ago, but with a much lighter bike I'm still thinking about it!
