A 1985 map shows a persistent ice/snow cover on Volcán Putana. The slopes of Volcán Putana drain north into the west-flowing Río Aguita Blanca, east into the Salar de Chalviri and southeast into the Río Blanco and from there into the Laguna Verde-Laguna Blanca system. The Río Putana originates on the northern flank of Volcán Putana, which forms its headwaters. It joins with the Río Jauna to form the Río Grande, which in turn joins the Río Salado to form the Río San Pedro de Atacama that eventually drains into the Salar de Atacama.
