A major flooding episode in 1605 ± 5 recorded from sediments of the Santa Barbara Basin has been attributed to the Huaynaputina eruption. A global cooling period associated with the Huaynaputina eruption as well as eruptions of Mount Etna and Quilotoa may have forced storm tracks and the jet stream south, causing floods in the Southwestern United States. At that time, flooding also took place in Silver Lake in the Mojave Desert, and Mono Lake rose to the highest level of the last thousand years. There were also wet spells between 1599 and 1606 in the Sacramento River system, according to analysis of tree rings. Colder temperatures may have contributed to the flooding in Silver Lake, as they would have reduced evaporation.
