The Santa Cruz River is one of the most significant waterways in Patagonia, originating from Lake Argentino at an altitude of 187 meters above sea level. It flows across the Santa Cruz Province from west to east for approximately 385 kilometers before emptying into the Atlantic Ocean near Puerto Santa Cruz. The river possesses a distinct glacial character, as it is primarily fed by the meltwater from the vast Patagonian ice fields. Its drainage basin covers about 25,000 square kilometers and plays a crucial role in the regional ecosystem of the arid steppe. In recent years, the river has gained international attention due to the construction of two massive hydroelectric dams, Condor Cliff and La Barrancosa. These projects are designed to significantly boost Argentina's energy capacity but remain controversial due to their potential environmental impact on nearby glaciers and biodiversity. The water often exhibits a milky turquoise hue caused by the high concentration of fine glacial sediment.
