The above map shows the average rainfall for each catchment that fell in the Fitzroy basin .

Rainfall in 2010-11 was far higher than the long-term average. This contributed to higher rates of erosion, increased soil loss and resulted and higher levels of suspended sediments and associated nutrients.

But it is not all bad news: wet years like 2010-11 help to rejuvenate aquatic ecology. Populations of macroinvertebrates and fish surge; wetlands and riparian zones are inundated and refilled, supporting vegetation growth and renewal.

Rainfall is a natural climatic driver and provides the source of water for our waterways. The amount, duration and intensity of rainfall impacts directly on water quality and ecology. The Fitzroy Basin has dry winters and wet summers and our reporting revolves around a water year (July to June) for this very fact. By July, rains have petered out and rivers have returned to base flows or, in most cases, stopped flowing completely. Mean annual rainfall varies from 600 mm in the west, to 800 mm in the east, peaking at 1000 mm in northern coastal area.
