In 1974 Lake Eyre was 6 m (20 ft) deep. Local rain filled Lake Eyre to 3.5 m (11 ft) in 1984 and 1989. Very heavy rain in January 2007 took about six weeks to reach the lake but put only a small amount of water into it.
The annual evaporation rate for the filled Lake Eyre ranges from 1800 to 2000 mm. The evaporation rate from the dry lake floor (excluding the salt crust) is of the order of 170 mm year-1 and the net evaporation rate from the salt-covered surface of Lake Eyre at between 9 and 28 mm year-1.
