Pellegrini Lake
 The Pellegrini Lake is an artificial lake located on the Argentine Patagonia in the province of Río Negro near the city of Cinco Saltos at approximately 38°40′S 68°00′W and 270 m above mean sea level.This reservoir was originally a natural depressed area possibly excavated by eolic forces which was later filled with water brought by a derivation channel from the nearby Neuquén River in order to regulate its flow (since the river had no natural lakes that would fulfill this function).
