Zackuse Creek Fish Passage and Stream Restoration

completed

Spawning areas for native kokanee salmon have reduced to a handful of tributaries to Lake Sammamish when once they were known to spawn throughout Lake Washington, the Sammamish River, and Lake Sammamish. The decline of the local population has been of special concern to Sammamish residents, fisheries and native tribes. Without diversity in available spawning habitat, a single localized event, whether natural or anthropogenic, could destroy the entire population. The Zackuse Creek Fish Passage and Stream Restoration project will aid in the reestablishment of Zackuse Creek as a kokanee spawning area. The project includes two primary objectives: Replace the existing culvert under East Lake Sammamish Parkway (ELSP) so that it is fully fish passable and with design elements that emulate a natural stream bed. Restoration of approximately 400 linear feet of Zackuse Creek upstream of the culvert.
