In the 1890s, two weirs were constructed on Falls Creek, high above the Trawool Valley, to supply water to Seymour.
The wall of the top storage (known as Falls Creek Reservoir) is built of locally quarried granite, which blends in particularly well with its surroundings. Granite was quarried in the Falls Creek valley in the 1890s and of interest are the large granite blocks that may be seen amongst the trees and ferns.
