Scott Lake is a lake in Thurston County, Washington, United States.[1] It is located 3.2 miles (5.1 km) south of the Tumwater city limits, 8.4 miles (13.5 km) south of the Olympia city limits, and 14.1 miles (22.7 km) north of the Centralia city limits.[7] The location for Scott Lake is in Sections 33 and 34, Township 17N, Range 2W, Willamette Meridian.[8]

The lake receives its water from a creek that comes out of Deep Lake. The creek is officially unnamed,[3] but is referred to as Spruce Creek by the Millersylvania State Park.

The creek that flows out of Scott Lake is officially named Allen Creek.[3] Allen Creek flows into Beaver Creek,[3] a tributary of the Black River. Thus it is part of the Chehalis River watershed.

A nine-hole golf course that is opened to the public,[9] and a private park opened only to residents of the Scott Lake Community are located next to the lake.

Eurasian water-milfoil (myriophyllum spicatum), an invasive species, was found in the lake in the spring of 1996.[10]

The area is subject to occasional flooding in winter. Its causes are being studied.[11]
