Yellow Lake (Sammamish, Washington)

Yellow Lake is located within Klahanie, a planned community that was annexed by Sammamish in 2016. The lake was named for its yellow water lilies, it is surrounded by a forested buffer strip, serving as an urban wildlife sanctuary. Due to this abundant habitat, it supports many birds and other wildlife. It is encircled by a walking trail.^[1][2]

The lake has not been monitored for nutrient levels since 2004, but those measurements indicate that it is borderline eutrophic. The lake has a 257-acre (104 ha) watershed, entirely within Klahanie.^[3] North Fork Issaquah Creek is the outflow of Yellow Lake.
