The flood producing rains were brought by a tropical depression which travelled from the Pilbara region of ~estern Australia across the continent to southeast Queensland. Rainfall in central Australia co~nonly results from easterly moving depressions, however OD this occasion the :-ainfall was exceptionally heavy. It is estimated that it released nearly 80 per cent of central Australia's annual a'Jerage rainfall in the 48 hour period". tlarch 30-31. Some 200mm of rain fell in Alice Spring~an6 parts of the Todd River catchment. The Todd River peaked at 1I.30am on March 31, at a gauge height of 3.98 metres. The flow was 1190 cumecs, with an ar-nual exceedence probability of 1 in 50 (l :50). River flooding was much less ext.ensive than indicated on the pre~ exiscing flood map, and was approximately equal to the flooded ~rea shown for the 1 in 20 event. Heavy rain in che city caused widespread flooding from direct local runoff and d~ain overflow in addition to river flooding. ?lood wate~ ente~ed some houses and businesses, but road transport both withi~ and outside Alice Springs was severely disrupted. !'.boriginal campers in the Todd River and adjacent a~eas '''e~e badly. effected.
