Fishery managers from Washington and Oregon added additional white sturgeon retention days in Bonneville Pool and The Dalles Pool as catch rates slowed in February and harvest was lower than expected.  Wednesday, March 9 and Wednesday, March 16 were added to the season for the Bonneville Pool from Bonneville Dam to The Dalles Dam.  For The Dalles Pool from The Dalles Dam to John Day Dam, Mondays, Wednesdays, and Saturdays in the month of March were added.  Fishery managers had closed sturgeon retention fishing in Bonneville Pool in late January because catch projections indicated the harvest guideline was close to being met.  It was later determined that the actual harvest was lower than expected so additional opportunity can be added without exceeding allowable catch.  Catch rates in The Dalles Pool slowed significantly in February and overall catch is well below original projections, so additional opportunity can be added.  This is the second extension for the 2022 sturgeon fishery in The Dalles Pool.
