Des Lacs River : ウィキペディア英語版 | Des Lacs River
The Des Lacs River is a river in central North America which flows through Saskatchewan and North Dakota. It originates in southeastern Saskatchewan and joins the Souris River, of which it is the primary tributary,〔 in Burlington, North Dakota. ==Natural history== The Des Lacs River was formed by catastrophic meltwater release from two large glacial lakes about 10,000 years ago.〔 The Des Lacs river is perennial, exhibiting many old oxbow lakes, meander scars, and relict channels. Prior to settlement, numerous riverine wetlands, ponds, and marshes were maintained by periodic flooding. With settlement of the region, the Des Lac river was significantly modified by drainage and channelization, and by construction of many low head dams along the river. Because of these changes, few natural riverine wetlands remain.
