Fishery officials are still considering options for eliminating Lake Davis' s population of razor-toothed northern pike, a fierce game fish that could threaten salmon and trout populations if it slips into the adjoining river system  Introducing pike-specific diseases and draining the lake have been ruled out  Four years ago, poison was added to the lake in order to eliminate the pike
This outraged local residents, because the water remained tainted for months and the region' s tourism economy suffered
The poison added to the lake four years ago was not successful in ridding the lake of the pike.
