Tully Falls

Tully Falls was formerly a large volume horsetail type waterfall which cemented itself among Australia's very best waterfalls. In 1960 the Koombooloomba Dam was built upstream of the falls, which diverts the vast majority (if not entirety) of the Tully River to a power station in the gorge well downstream of the falls, and as a result the falls only flow during periods of heavy rain. Like Barron Falls, also afflicted by a hydroelectric diversion which saps the falls nearly dry outside of the monsoon season, it is likely that Tully Falls flows regularly during the wet months, but because the area around Tully Falls isn't nearly as developed as is Barron Falls, very little information has surfaced supporting this posit.
The height of Tully Falls is commonly reported as 293 meters (961 feet), but it is almost certain this is the measure of head which the hydroelectric facility operates at, rather than the actual height of the falls. Topographic maps indicate the falls are more accurately about 160 meters (525 feet) in height.
