Monitoring of the Wanapum white sturgeon subpopulation has been limited. A 2002 survey resulted in a population estimate of 551 white sturgeon. During this survey, 20% of the white sturgeon that were collected were juveniles, suggesting that natural recruitment or the addition of juveniles from upstream reservoirs is occurring in Wanapum Reservoir.
