The Hutton tui chub (Gila bicolor ssp.) is represented by a single population that inhabits Hutton Spring on the southwest side of Alkali Lake in Lake County, Oregon.  The Hutton tui chub was listed as threatened under the federal Endangered Species Act in 1985.  In 2005, the Native Fish Investigations Project initiated Hutton tui chub investigations to monitor 1) population abundance, 2) age composition, and 3) habitat conditions.

The Hutton tui chub is one of several morphologically diverse, allopatric populations of tui chub that inhabit the five endorheic basins of south-central Oregon.  Hutton Spring is located on private land and the habitat is in good condition, primarily due to conscientious long-term land stewardship by the landowner.  The habitat is currently fenced from cattle grazing and is in stable condition.  Hutton Spring has been diked and has a pool approximately 10 meters wide, 2 meters deep and is surrounded by rushes.  A second unnamed spring (3.3 meters wide and 0.7 meters deep) was reported to contain Hutton Spring tui chub but was not located in recent surveys.

The Recovery Plan for the Threatened and Rare Native Fishes of the Warner Basin and Alkali Subbasin states that this species will probably not be delisted in the near future because of its extremely isolated range and potential for degradation of its habitat from localized events.  The primary recovery objective for this species is the long-term persistence through preservation of its native ecosystem.  The plan further states that the conservation and long term sustainability of this species will be met when: 1) long-term protection to its habitat, including spring source aquifers, springpools and outflow channels, and surrounding lands is assured; 2) long-term habitat management guidelines are developed and implemented to ensure the continued persistence of important habitat features and guidelines include monitoring of current habitat and investigation for and evaluation of new spring habitats; and 3) research into life-history, genetics, population trends, habitat use and preference, and other important parameters is conducted to assist in further developing or refining criteria 1) and 2), above.  Actions needed to meet these criteria include protecting and rehabilitating fish populations and habitats, conserving genetic diversity of fish populations, ensuring adequate water supplies are available for recovery, monitoring population and habitat conditions, and evaluating long-term effects of climatic trends on recovery.
