<P> Devils Lake is located in Ramsey County and Benson County in northeastern North Dakota . The Spirit Lake Tribe occupies most of the southern shore and has been adversely affected by flooding since the 1990s . </P> <P> Devils Lake is the endorheic, or closed, lake of a drainage basin of some 3,800 sq mi (9,800 km), the Devils Lake Basin . The lake collects around 86 percent of the basin's water runoff . Above an elevation of 1,447 ft (441 m) AMSL, the lake spills into neighboring Stump Lake . At 1,458 ft (444 m), the combined lake flows naturally into the Sheyenne River, though the lake has not reached this level in approximately 1000 years . The Sheyenne River is a tributary to the Red River, which flows into Canada, with eventual exit into the Hudson Bay . Dike protection is set at 1,454 ft (443 m). </P> <P> Under normal conditions, Devils Lake is shallow, saline, and hypereutrophic (very high in nutrients). During periods of excessive precipitation, however, the lake can be up to 60 ft (18 m) deep, eutrophic (rich in minerals, nutrients, and organisms), with decreased salinity due to dilution . </P> <P> Because Devils Lake is endorheic, the lake tends to be much higher in salinity than are lakes with outlets to river systems . This is similar to the Great Salt Lake in Utah . Lower water levels increase salinity threatening fish and wildlife . Salinity levels in the lake have been one prominent aspect of the debate over diversion of lake water into the Sheyenne River, with questions of the potential environmental impact of the diverted water on downstream rivers, lakes, and communities . </P>
