Title: Laboratory tests to assess water-level fluctuations at Vernita Bar, Washington, USA. [Effects on chinook salmon redd]

Vernita Bar chinook salmon redd dewatering was simulated in gravel-filled aquaria. Dewatering before hatching did not affect survival; after hatching a few hours of dewatering was fatal. Weather conditions at Vernita Bar was not a factor in assessing dewatering effects. Above-ground watering of dewatered redds may protect alevins and eleutheroembryos.
