2016/17年冬季，加州经历了多次与大气河流（AR）降落有关的强降水事件，这些河流填满了水库，结束了多年的严重干旱。这些事件还造成洪水、泥石流和泥石流，造成重大的社会经济破坏。2017年2月2日至11日，北方塞拉内华达州持续强降水，导致奥罗维尔湖水位迅速上升，自奥罗维尔大坝安装以来首次启动紧急溢洪道，迫使188，000人撤离。降水，其中大部分下降为雨，由于冻结水平升高，是集中在西坡的内华达州与地形强迫连接到两个连续的AR。大雨落在饱和的土壤上，加上先前风暴产生的积雪，导致大量径流流入奥罗维尔湖，导致溢洪道受损，水库运行复杂。
During winter 2016/17, California experienced numerous heavy precipitation events linked to land-falling atmospheric rivers (ARs) that filled reservoirs and ended a severe, multiyear drought. These events also caused floods, mudslides, and debris flows, resulting in major socioeconomic disruptions. During 2–11 February 2017, persistent heavy precipitation in the northern Sierra Nevada culminated in a rapid increase in the water level on Lake Oroville, necessitating the activation of an emergency spillway for the first time since the Oroville Dam was installed and forcing the evacuation of 188,000 people. The precipitation, which mostly fell as rain due to elevated freezing levels, was focused on the western slope of the Sierra Nevada in connection with orographic forcing linked to two successive ARs. Heavy rain fell on saturated soils and a snowpack produced by antecedent storms and thereby resulted in excessive runoff into Lake Oroville that led to a damaged spillway and complicated reservoir operations.
