The mill was probably fed by a headrace or underground channel. Also on the property are the watercourses, consisting of the headrace, pond, and dam. The TBM for the headrace tunnel broke through, completing it on August 11, 2009. Before reaching the power station, water is diverted through a headrace tunnel. The headrace tunnel is long, wide and high. Water from the lake is fed to the power station via a headrace tunnel. The dam and headrace are laid out along natural rock formations in the river. About ten days after the project was completed, about of the headrace tunnel collapsed.
