A survey of springs and rapids along the Katherine and Daly Rivers

A boat traverse was done of the Katherine and Daly Rivers from Galloping Jacks to Florina homestead. River bank springs were found to be numerous, especially between Limestone Creek and the Flora River. The springs have small discharges and are mostly sourced from the “massive unit” of the Oolloo Dolostone. The locations of approximately sixty rapids were recorded. They break the river into a series of steps and pools. Cretaceous sandstone is a very hard rock and is the formation that most rapids are formed on. The geology along the traverse has been reinterpreted slightly. Rocks along the Daly River, just north of the Flora are now regarded as Jinduckin Formation rather than Cretaceous as was previously thought.
