===Watersheds===
[[File:DanaFork.JPG|thumb|right|The Sierra hosts many waterways, such as the [[Tuolumne River]].]]
The range is drained on its western slope by the [[Central Valley (California)|Central Valley]] watershed, which discharges into the Pacific Ocean at [[San Francisco]]. The northern third of the western Sierra is part of the [[Sacramento River]] watershed (including the [[Feather River|Feather]], [[Yuba River|Yuba]], and [[American River]] tributaries), and the middle third is drained by the [[San Joaquin River]] (including the [[Mokelumne River|Mokelumne]], [[Stanislaus River|Stanislaus]], [[Tuolumne River|Tuolumne]], and [[Merced River]] tributaries). The southern third of the range is drained by the [[Kings River (California)|Kings]], [[Kaweah River|Kaweah]], [[Tule River|Tule]], and [[Kern River|Kern]] rivers, which flow into the [[endorheic basin]] of [[Tulare Lake]], which rarely overflows into the San Joaquin during wet years.

The eastern slope watershed of the Sierra is much narrower; its rivers flow out into the endorheic [[Great Basin]] of eastern California and western [[Nevada]]. From north to south, the [[Susan River (California)|Susan River]] flows into intermittent [[Honey Lake]], the [[Truckee River]] flows from [[Lake Tahoe]] into [[Pyramid Lake (Nevada)|Pyramid Lake]], the [[Carson River]] runs into [[Carson Sink]], the [[Walker River]] into [[Walker Lake (Nevada)|Walker Lake]]; [[Rush Creek (Mono County, California)|Rush]], [[Lee Vining Creek|Lee Vining]] and [[Mill Creek (Mono Lake)|Mill]] Creeks flow into [[Mono Lake]]; and the [[Owens River]] into dry [[Owens Lake]]. Although none of the eastern rivers reach the sea, many of the streams from Mono Lake southwards are diverted into the [[Los Angeles Aqueduct]] which provides water to [[Southern California]].
