As an introduction to the widely spread features of Wayatinah, the Derwent River runs in a south easterly direction past many acres of State Forest before flowing into the expansive Wayatinah Lagoon, a waterstore located five or so kilometres north of the Wayatinah Power Station. The Lagoon’s water is piped to the Station first underground and then overground in massive white pipes.
Excess water from the Lagoon seeps, dribbles or spills back into the Derwent River at the Wayatinah Dam, which isn’t far from the Wayatinah township. Then the low water level of the river trickles over a rocky base until it catches the flow of the Florentine River before continuing on to become part of Lake Catagunya. The western most reaches of the Lake have already formed before the river reaches the Wayatinah Power Station.
