Stump Lake is a 10-mile long, 2 1/2-mile wide "L"-shapped lake located in east central North Dakota in Nelson County about 5 miles southeast of Devils Lake and 65 miles west of Grand Forks.
Stump Lake's importance as a breeding ground for migratory waterfowl was recognized by the federal government in 1905. Five islands with a total land area of about 30 acres in the western end of the lake were designated as a national bird reservation by President Theodore Roosevelt.
The lake was popular with oologists (the branch of ornithology that focuses on the study and collection of birds eggs). The practice may have been as popular a pursuit in the late 19th and early 20th centuries as stamp and coin collecting is today. However, by 1940 oology as a popular hobby had died due to a burgeoning conservation consciousness in this country.
