Small-Boat Harbor Dredging, St. Paul, Minnesota

The St. Paul Small-Boat Harbor is on the lower end of Harriet Island in St. Paul, Minnesota, at Upper Mississippi River mile 839.6 on the right descending bank. The length of the harbor is 2,375 feet; the width varies from 200 to 400 feet. The Corps of Engineers is authorized to maintain the harbor to a depth of 5.0 feet below low control pool elevation of 687.2 feet mean sea level (msl). The city of St. Paul is the non-Federal sponsor for the project and is required to furnish a suitable placement site for the dredged material.

Mississippi River Locks and Dams 2–10 Guidewall Crib Repairs

Guidewalls are integral to each of the Mississippi River Locks and Dams 2 through 10. Guidewalls are long extensions of the lock walls, in either the upstream or downstream direction, that are parallel to the lock wall. These walls serve primarily to guide the long tows into the lock and to provide mooring facilities for tows too long to be accommodated in a single lockage. The guidewalls are constructed of multiple 35 to 40 feet length concrete monoliths with rock filled timber cribs beneath and behind them.

Continuing Authorities Program: Emergency Streambank Protection – Section 14, Waste Water Treatment Lagoons, Village of Colfax, Wisconsin

The Village of Colfax is located in Dunn County, Wisconsin, approximately 75 miles east of St. Paul, Minnesota. The erosion site is located on the left descending bank of the Red Cedar River, less than one mile downstream of Colfax, at the Village of Colfax Waste Water Treatment Lagoons. Erosion has cut the bank to within 50 feet of the waste water treatment lagoon berm which threatens the integrity of the berm. Severe safety and environmental impacts would occur if erosion continues at this location and waste water from the lagoons was to enter the Red Cedar River.

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.
