Curlew Lake is a 921-acre body of water located in Ferry County, northeastern Washington. The lake is 5.5 miles long and offers diverse paddling opportunities. Access is available at Curlew Lake State Park on the southern end, which provides a no-fee boat ramp and an 80-foot dock. Additional access points include Tiffany's Resort, Fisherman's Cove Resort, and Black Beach Resort.

The lake's geography is characterized by three deep basins and steep shorelines. Its southern end is narrower and dotted with small islands, making it particularly appealing for kayaking and canoeing. The central section of the lake is wider, accommodating various water activities.

Paddlers should be aware of potential hazards, including toxic algae blooms that have occurred in recent years. Water quality has been a concern, with decreases in clarity and increases in aquatic weeds noted. The lake is strongly stratified from April through October, with a thermocline at approximately 5 meters depth.

Wildlife viewing opportunities abound. Bald eagles, ospreys, and great blue herons nest on the lake's tree-lined islands and can often be seen fishing. In spring and fall, migratory birds such as swans and snow geese use the lake as a stopover. The lake is also home to various fish species, including rainbow trout, bass, yellow perch, and tiger muskies.

Curlew Lake State Park offers amenities such as picnic areas, restrooms, and camping facilities. The park is open from April 7 to October 31, with summer hours from 6:30 a.m. to dusk. A Discover Pass is required for park entry.

For an extended paddling experience, the Ferry County Rail Trail runs along the entire west shore of the lake, offering scenic views and potential rest stops. The lake's pine-covered hills and green lawns provide a picturesque backdrop for paddling adventures.
