During the Tauca phase, water levels in Laguna Miscanti were higher than today; shorelines formed from an event in Ch'iyar Quta and Lake Tuyajto; saline lakes formed in the Lipez area, and water levels rose in the Guayatayoc-Salinas Grandes basin, in Laguna de Suches in Peru and lakes at Uturuncu and Lazufre. Some Atacama Altiplano lake levels increased by , and evidence exists at the Quebrada Mani archeological site for a higher water supply 16,400-13,700 years ago. During the Tauca, greater flow occurred in rivers in the Atacama region as well as a higher groundwater recharge; more precipitation fell in the Rio Salado valley; the excavation of the Lluta River Valley and the Colca Canyon may have been aided by an increased water supply, groundwater-fed wetlands developed in the Cordillera de la Costa, and glaciers advanced in the Cordillera de Cochabamba. A moraine formed at Hualca Hualca; the Choqueyapu II glacier in the Eastern Cordillera advanced; moraines formed from glacial advances in Argentina (including the Sierra de Santa Victoria); basal sliding glaciers formed at Sajama; glaciers and probably also rock glaciers grew at Sillajhuay; landslide activity in northwestern Argentina decreased; alluvial fans were active in the Cordillera Oriental of Peru; the climate grew wetter over the southern Amazon; flooding in the Río Paraguay-Parana basin and precipitation and forest cover in Pampa del Tamarugal increased; the vegetation limit in the Atacama desert descended towards the coast; groundwater discharge in the Atacama increased; the Pica glass formed in the Atacama as a consequence of increased vegetation and the occurrence of wildfires in this vegetation and plant pathogens such as rust fungi were more diverse than today, Prosopis tamarugo grew at higher altitude thanks to a better water supply; river incision changed, erosion occurred along the Pilcomayo, and an increase in Pacific plankton was probably linked to increased runoff (and an increased nutrient supply) from the Andes. A glacial advance in central Chile around 15,000 years ago, also associated with increased precipitation and the Lake Tauca period, was probably triggered by tropical circulation changes. The well dated record of Lake Tauca has been used to correlate climatic events elsewhere in the region.
