Lake Eyre Basin

March 2018 Summary

Mean rainfall was 65 mm, 124 per cent higher than the long-term mean of 29 mm for March. While rainfall in the southern part of the region was below average, low pressure systems and remnants from cyclone Nora brought above average rainfall to large areas in the north.

Due to these wet conditions, the fourth highest streamflow since 1980 for March was recorded for the headwater catchments of Copper Creek: the Darr and Thompson River near Longreach as well as at the Barcoo River. However, no significant flows were recorded at Cooper Creek at Cullyamurra Water Hole station, possibly due to losses given the long traveling time of more than 700km between these stations.
