Lake Gairdner Catchment
This map defines 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.
And here is the catchment boundaries draped over the satellite image for the Lake Gairdner area.

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
These images have been lifted from USGS LandsatLook Viewer showing images from around the time of each Speed Week. They can be used as a comparison when trying to favourable conditions at the lake.
