UncertaintyWhat are the impacts of climate change on sturgeon? Can white sturgeon condition and spawn timing be possible responses to, and a potential bellwether for, systemic changes of Columbia River reaches due to global climate change? What are the effects of water temperature increases, changes in the seasonality of the freshet and low elevation runoff, and possible changes in salt-wedge intrusion on white sturgeon spawning success and population dynamics in Columbia River waters? What are the effects of the above mentioned climate changes on white sturgeon food resources in Columbia River reaches, including the Columbia River mainstem, estuarine, and marine waters?
