Lake Gairdner Catchment

The first two maps define the drainage catchments for Australia.
The Gairdner catchment (1) is in the Western Plateau Division (XII).

6 creeks and rivers feed the lake: Garden Well Creek, Gorge Creek, Yeltabinna Creek to name a few.

Usually, those creeks are dry as well, they only flow for a short period after rain. There are no major entry points for rivers and creeks to Lake Gairdner other than from the very North-West tip. Even when it does rain north of the Lake it takes a couple of weeks to get down to where Speed Week is conducted.


For more detailed information go to the South Australian Flood Warning Centre web page.



Evaporation is dependent on sunshine, temperature, humidity and wind, and is measured as a potential value, assuming an unlimited water supply. Average evaporation rates in the Outback are greater than 3,400 to 4,000 mm per annum. (70 - 100mm per week)


Land Sat images for each year
