Land use in this subarea consists primarily of water-dependent commercial and industrial uses, such as marinas, commercial shipyards, and commercial and residential development bordering the shoreline of Lake Union. Relatively little is known about the natural history of salmon that utilize Lake Union for transportation and juvenile rearing. However all naturally produced anadromous fish in the Lake Washington/Cedar/Sammamish watershed use Lake Union as a migratory passageway to Puget Sound.
