The Garrison Concourse was extensively restored beginning in 2011. Ice and wave action had taken a toll on the overlook wall, and the plaza had deteriorated. The Preservation Alliance of Minnesota had placed it on their 2010 "10 most endangered historic places" list. The state highway department—now renamed the Minnesota Department of Transportation (MnDOT)—performed the work to meet federal standards for historic properties. Loose stones were reset and missing stones replaced with similar material. Several stones knocked out of the overlook wall were recovered from the lakebed and fitted back into place. Repairs were made to the plaza and flagpole monument. The walleye statue and information booth, which had been placed in the middle of the plaza in the late 20th century, were moved a short distance to be less visually obtrusive.
