Umpqua chub

Species of fish

The Umpqua chub or Umpqua Oregon chub is a species of freshwater fish in the family Cyprinidae. It is found only in the Umpqua River and partially in its tributaries, Oregon in the United States, making it an endemic species to that watershed. While geographic populations are split into six regions, genetic studies suggest that there are four genetically distinct populations: Smith River, Elk Creek, Calapooya Creek-Olalla Creek, and Cow Creek-South Umpqua River.
