King County Executive Dow Constantine, Issaquah Mayor Ava Frisinger, Sammamish Mayor Don Gerend, Bellevue Mayor Don Davidson, plus representatives of the U.S. Fish and Wildlife Service, the Washington Department of Fish and Wildlife and local volunteers will come together Monday at a ceremony marking the conclusion of another season of Lake Sammamish kokanee salmon restoration work.

The event, from 1-3 p.m., will take place at Hans Jensen Park at the north end of Lake Sammamish State Park in Issaquah.

The event will be highlighted by the release of 100 juvenile kokanee salmon – the last of 30,000 kokanee that were reared in a unique, cooperative emergency supplementation project this past winter. The parent fish of these kokanee were collected from Sammamish watershed creeks in an effort to boost the stock’s population and halt its slide toward extinction.

Extensive surveys of the spawning grounds this past fall and early winter indicated that the 2010-11 spawning run is one of the smallest in a decade or more, making the emergency supplementation program all the more important to the ongoing survival of Lake Sammamish kokanee.
