Warroad Harbor and River Harbor Dredging
Location/Description
|
Warroad Harbor is located in the city of Warroad on the western shore of Lake of the Woods approximately 6 miles south of the Canadian border in northwestern Minnesota. The project is authorized for maintenance of an access channel and harbor to a depth of 8.0 feet below low water datum of 1056.0 feet above mean sea level. The channel is approximately 9,200 feet long and varies in width from 100 to 300 feet. Maintenance dredging has been curtailed to a depth of 7 feet and a width of 100 feet. Dredging of 9,000 cubic yards was completed in April 2007. Prior to the 2007 dredging, the channel was last dredged in 1996. No additional dredging is planned.
|
Status
|
Approximately 6,000 lineal feet of channel and an estimated 50,000 cubic yards required dredging in 2007. Flash flooding in summer 2002 caused significant shoaling. At low water datum, the channel was virtually impassable. A dredging contract to excavate 18,000 cubic yards of material through the ice was awarded in spring 2007. Work began in March 2007 and continued for three weeks into the first week of April 2007.
Because of an unseasonably warm week in April, about half the goal was achieved when operations were halted. Approximately 1,800 feet of the channel that extends into the lake is the highest priority for future dredging operations. Dredging this channel is estimated to require the removal of approximately 10,000 cubic yards of material. Actions to implement this additional dredging will be initiated when funding is made available to the Warroad Harbor project.

Authority
|
River and Harbor Acts of 1899, 1900, 1905, 1909, 1912 and 1926 and Public Law 93-251. House Documents 92-56-2, 703-61-2 and 467-69-1.
|
Fiscal
|
Project design and construction costs are 100 percent federal. Funding in the amount of $222,000 was last appropriated to this project in fiscal year 2006. The city of Warroad, as non-federal sponsor for the project, is responsible for providing a site for the placement of the dredged material and securing the right-of-way for the site.
