The Ord River irrigation setup is amazing.
Some stats:
The Dam wall is 335m long, was built commencing in 1969 and cost $22m. It's all that holds back a body of water equal to 19 Sydney Harbours (it used to be 21 but Sydney did some remeasuring and they discovered it to be slightly bigger). It is about 1000km2. In 2011 it reached 9m above it's usual level and spanned 1600km2. It contained 38 Sydney Harbours at that time. It is not an irrigation dam but rather keeps a steady supply of water to Lake Kununurra as well as generating some power. Lake Kununurra is the irrigation dam and services about 10000 hectares. Indian Sandelwood, Rice and etc are the main crops.
It's 55km by river from the Dam wall back to Kununurra town. We travelled down it in a boat powered by 3, 250hp V8 outboard Yamahas. It was a nice ride.
