Two recreational white sturgeon fisheries in the Columbia River upstream of Bonneville Dam will close within the next few days under rules adopted by Oregon and Washington fishery managers from Oregon and Washington.  Retention sturgeon fishing will close in Bonneville Pool and adjacent tributaries effective at 12:01 this Friday morning, and in The Dalles Pool and adjacent tributaries effective at 12:01 this coming Tuesday morning.  The closures were adopted by the two states after reviewing survey data that indicated the fisheries are approaching their respective harvest guidelines.  Recreational sturgeon anglers have harvested an estimated 83% of the Bonneville Pool guideline and 76% of The Dalles Pool guideline as of February 9, and improved weather has allowed catch rates to improve.  Retention sturgeon fishing remains open in John Day Pool, where anglers have harvested an estimated 37 sturgeon toward their guideline of 105 legal-sized fish.   Catch-and-release sturgeon fishing remains open in all three pools, except in the spawning closure areas which will be in effect May 1 through August 31.
