Fishery managers in Oregon and Washington say the recreational sturgeon season in The Dalles Pool, from The Dalles Dam upstream to John Day Dam, will close effective at 12:01 Saturday morning.  The states decided to close the sturgeon sport fishery based on catch projections which indicate the 100 fish guideline will be achieved by Friday evening.  Catch rates have been high since the season opened January 1, with an estimated 69 fish kept through January 14.  Sturgeon fishing remains open in the Bonneville and John Day pools, where the guidelines are 325 and 105 fish, respectively.  Retention sturgeon fishing is closed below Bonneville Dam and below Willamette Falls under permanent sport fishing regulations.  Except for specific sanctuaries, catch-and-release sturgeon fishing remains open in all of these waters, even when retention seasons are closed.
