Gawler-Craton

Summary Rama One is a permanent freshwater reservoir 20 kilometres long, 5 kilometres wide, and 50 metres deep on average — sited on the Gawler Craton western shore of Kati Thanda (Lake Eyre), not within the lake basin itself. It is long and thin by design. The shape follows the Gawler Craton terrain — ancient stable geology rising naturally to the west, north, and south, providing containment on three sides without engineered dam walls. The eastern boundary faces Kati Thanda, managed through inlet and outlet structures rather than a berm. ...

Summary The Rama Reservoir Chain is a chain of Rama nodes — each 20km × 5km × 50m — stepping south along the Gawler Craton western corridor from the latitude of Kati Thanda to the corridor high point, approximately 400km. The chain does not reach Port Augusta directly. From the terminal node, a gravity-fed pipeline descends to Port Augusta and Spencer Gulf — water flowing downhill, energy recovered through inline hydro-turbines on the descent. ...

Summary Rama is not a city built near a lake. It is a chain of sixteen permanent freshwater reservoirs, each with a city arc on its western shore, stepping 400km south along the Gawler Craton from the latitude of Kati Thanda to the corridor high point east of Woomera. From there a gravity-fed pipeline descends to Port Augusta and Spencer Gulf — water flowing downhill, energy recovered on the descent. ...
