Crater Island closed over Memorial Day weekend

The project is expected to last through June 13th

A popular river destination for boaters will be closed over Memorial Day weekend.

The Mississippi River’s Crater Island will be closed during the Memorial Day weekend due to ongoing dredging activities.

The Corps of Engineers is currently in the process of removing 150,000 cubic yards of dredged material at the temporary dredge placement site near Brownsville, Minnesota. The project is expected to last through June 13.

The material is being moved from Crater Island, a temporary dredged placement site, to a permanent location at the Brownsville Containment Site.

Approximately 80,000 cubic yards of dredged material will be used as fill material for the I-90 bridge project.

The cove area at Crater Island will be reopened to the public once the dredging activities are complete.

The dredging is required to restore site capacity for future hydraulic dredging needs, which are required to maintain the Mississippi River 9-foot navigation channel.
