The flooding and diverting of Devils Lake has been a financial, environmental, international treaty, water quality control, and legal issue for years. The outlet drew opposition from the governments of Minnesota and Manitoba. They argue the outlet would create the potential for the transfer of unknown foreign aquatic species and high levels of sulfates into the Red River basin and Lake Winnipeg, the world's 10th-largest freshwater lake. Devils Lake citizens and north Dakota are also concerned because, due to the rising waters of the Devils Lake and its basin, streams can flow in two directions: into the Red River Valley or the Devils Lake Basin. The Red River Valley basin contains a "rough fish", the common carp, which the North Dakota Game and Fish Department fears will enter Devils Lake basin waters in the near future, allowing the carp to populate Devils Lake. The carp's fast reproductive growth and the lack of carp predators in the lake will likely help it to dramatically increase in population. This could have drastic consequences for existing populations of game fish such as the walleye and northern pike, which could greatly harm the sport fishing industry. |
