Kokanee Conservation Supplementation Plan

The Lake Sammamish Kokanee Work Group is pleased to share the 2013 Conservation Supplementation Plan for Lake Sammamish Late-run Kokanee. This plan alone has provided operational guidance for the Lake Sammamish late-run kokanee supplementation program from the 2010-2011 return year through the 2014-2015 return year.  The plan is reviewed annually and then revised as needed. In lieu of major revisions to the Plan for the 2015-2016 return year, program managers have prepared a short Supplement to the Plan that provides detailed direction building on the full Plan for the 2015-2016 and 2016-2017 return years.  The 2013 edition of the Plan and the 2015 Supplement together supersede all prior documents pertaining to the use of artificial propagation methods to prevent the extinction and contribute to the recovery of native kokanee in the Lake Washington/Sammamish watershed.

This plan is the product of a collaborative effort by the U.S. Fish & Wildlife Service, King County Department of Natural Resources and Parks, and Washington Department of Fish and Wildlife. The authors encourage the Kokanee Work Group and everyone with an interest or a role in kokanee recovery to consider the supplementation program a complement to, not a substitute for, the protection and restoration of the stream and lake habitat that will provide the best assurance that our kokanee population will recover and sustain itself for generations to come. 

The Kokanee Work Group extends thanks to the contributing authors, including:

  • From the US Fish and Wildlife Service: Jeff Chan, Joy Evered, Denise Hawkins, Sharon Lutz, Dan Magneson, Roger Tabor, Brad Thompson, and Dave Zajac.
  • From the Washington Department of Fish and Wildlife: Aaron Bosworth, Darin Combs, Bethany Craig, Doug Hatfield (retired), Annette Hoffman,
