The Upper Snake White Sturgeon Management Unit, which contains five subpopulations, represents the uppermost natural distribution of white sturgeon in the Snake River. Limiting factors in this reach of the Snake River severely restrict spawning success, recruitment and subsequently population growth. Of the five subpopulations, only the subpopulation between C.J. Strike and Bliss dams is characterized as abundant and productive. This subpopulation is considered viable and is managed as a core conservation population by the Idaho Department of Fish and Game. Factors such as habitat fragmentation, flows, and water quality are limiting the abundance and productivity of the subpopulations in the Upper Snake Management Unit.

Although catch-and-release fishing is allowed, harvest of fish from the Upper Snake White Sturgeon Management Unit is prohibited.
