What happens to the water when it Pasess through the Barmah Choke?
Research from the MDBA shows capacity through the Barmah Choke is decreasing. Research shows the amount of water that can flow through this section of the river has decreased over the last 3 decades from 11,300 ML per/day to 9,200 ML/day. This means around 20% less water can flow through this reach in summer.

Why are there so many fault lines in Australia?
A fault is a crack in earths crust, it happens from putting so much stress on a rock that it just eventually snaps and breaks. Australia is a geologically active continent containing moving fault-lines, a long history of mountain making, and has regular seismic activity.
