Curlew Lake State Park, Recreational park in northeastern Washington, United States.

Curlew Lake State Park is a recreational area in northeastern Washington spanning about 87 acres along a lake that stretches 5.5 miles. The park provides boat launching facilities, dock space for mooring, and dedicated camping zones with tent and utility sites.

The Washington Department of Game developed the site for public fishing in 1948. In 1958, the Washington State Parks and Recreation Commission agreed to use the land for state park and recreational area development, and the legislature appropriated $25,000 in 1959.

The park's name comes from the long-billed curlew, a shorebird of the region's wetlands and grasslands. Fishing is the main draw: the lake holds rainbow trout, largemouth bass and yellow perch, and the eastern shore gives anglers room to cast from the bank. Campers stay in tent and utility sites close to the boat launch.

The site has basic facilities including restrooms and showers for visitors spending time by the water or camping overnight. These amenities are straightforward to use and support both day visits and extended stays.

The park's 87 acres were first developed by the Washington Department of Game in 1948 as a public fishing site, a decade before the land was turned over to the state parks commission. The legislature set aside $25,000 for that development in 1959.
