Over time, some of the Mitchell River's former headwaters were diverted by natural forces into the Barron. These include the Clohesy River and other tributaries that used to flow northwest to the Gulf of Carpentaria. With the extra water now flowing over the -high Barron Falls, the steep, narrow Barron Gorge was formed. Much of the water that used to flow over the falls has now been diverted in upstream dams and used to generate electricity at the Barron Gorge Hydroelectric Power Station.
