History
The river was named Fall River by John Frémont in 1848 because of its historic cascades and falls at the terminus of the river.Ecology and conservation
The Fall River Conservancy and the Fall River Resource Conservation District both work to restore the river. The former has worked with the University of California Davis to study the trout and identified two distinct sub-populations, one adapted to the colder winter flows of Bear Creek and one adapted to the more constant temperature spring-fed waters of Spring Creek and the Fall River mainstem. The large volume of spring water inflow maintains Fall River water temperature at near optimum ranges for trout production, even during mid-summer. The upper river has historically been characterized by abundant aquatic macrophytes, including extensive meadows of horned pondweed (''Zannichellia palustris''), however these have dramatically declined due to excessive sediment deposition due to fires in the watershed and channelization of a tributary stream.Watershed and course
The Fall River watershed drains a area that originates from Thousand Springs, and is largely spring-fed, with Bear Creek providing the only significant precipitation-related surface flow to the river. Bear Creek rises at a source elevation over and flows east to join Fall River at Thousand Springs at an elevation of .U.S. Geological Survey.
