THE
SPILLWAY
The Spillway is an
overflow system for Lake Argyle, acting as a safety valve when high
flood conditions are prevailing.
This fast flowing
water spillway was blasted through a granite hill, creating a 2.2
kilometre channel section, to provide a natural overflow facility.
The run off flows back into the upper reaches of Lake
Kununurra.
In 1995 a six metre
plug was put in the mouth of the spillway in order to increase the
head of water available for the Hydro Power Station.
This photo was taken
in the Wet Season and the flowing water will be much less in the
Dry Season.
The cache is a small magnetic key box
with a log sheet and you will need to bring your own
pen.
