The level of Lake Rico reached a difference of 3.7 m and the evacuation of the liquid lasted 65 days, reaching a maximum discharge flow of 220 m³ / s. Minor discharge ruptures Occasionally, the glacial front does not completely obstruct the natural passage of water with an ice dam, but it approaches close enough to prevent water from passing freely, so without reaching elevation, an arm cut in Rico occurs. These events are classified as minor downloads. This is what happened in October 1996, when the Rico arm rose about a meter. At the end of that month the water pressure opened a greater passage in the walls of the glacial front and the discharge began, but slowly, since the passage had not been sufficiently open, so the maximum peak of the discharge flow occurred at the end of January with a value of 123 m³ / s, the dimensions being equalized on both sides only at the beginning of April.8 The events of 1994, 1995 and 1997 show similar behavior and magnitudes to those of 1996. Other featured events The phenomenon was presented again in 1935. At the close of 1939, due to the flooding caused by the embalmed waters, which affected numerous agricultural establishments, and without even glimpsing the economic value that from the point of view this natural event could represent tourism, the Argentine Navy Ministry launched explosives on the ice indication, unable to obtain the intended result of artificially consolidating a gap for the evacuation of water. The break occurred naturally in February of the following year. In 1952 the closure produced a flooded area of 6670 ha; It affected fields of crops and livestock, but not buildings. The rupture of 1966 was the one that produced one of the largest volumes of water evacuated by the Santa Cruz River, which exceeded 2000 m³ per second, measured at the Charles Fuhr capacity station. Tourism Due to its size and accessibility, Perito Moreno is one of the major tourist attractions in southern Patagonia and the rupture of this glacier is considered one of the most impressive natural spectacles in the world. The rupture events benefit the area by producing enormous international visibility, which translates into sources of income for the region's growing tourism development, which has its support base in the city of El Calafate. The city has an international airport, with many tour companies running
