Mississippi River Basin: Regional Discharge-Frequency Study

The Upper Mississippi River corridor is a popular vacation and retirement area and is experiencing continued growth. Much of the area has not been previously studied, and flood risks have not been adequately defined. The Upper Mississippi River Regional Discharge-Frequency Study is conducting hydrologic analyses for development of a consistent set of frequency distributions for discharge and elevation for the Upper Mississippi River from the headwaters area of Lake Bemidji downstream to St. Paul, Minnesota. This study will directly inform floodplain management decisions in 13 counties in Minnesota.

Souris Court Levee Repair, Minot, ND

The Souris River flows from Saskatchewan, Canada into North Dakota and then back into Canada. Minot is a city located in north central North Dakota with a population of approximately 46,000 residents. Above normal precipitation during the summer and fall of 2010 left much of the eastern portion of Saskatchewan saturated. The winter of 2010 and 2011 then saw snowfall significantly above normal throughout the basin. The Souris River in the Minot area started to rise in April 2011 and continued to rise throughout May 2011.

Souris River Hydrology and Hydraulics Studies

The Souris (Mouse) River is located in Saskatchewan and Manitoba, Canada, and North Dakota. The headwaters of the basin comprise several rivers in Saskatchewan that meet near the international border and flow into North Dakota. The Des Lacs River joins the Souris upstream of Minot near Burlington, North Dakota. The Souris River then flows through Sawyer and Velva, North Dakota, before turning back to the north and flowing into Manitoba.
