PIERRE, S.D.(WNAX)- A new report from the National Park Service shows more visitors to the Missouri National Recreational River are having a big economic impact.

The report says over one hundred forty thousand visitors in 2021 spent almost seven million dollars in the area.

Rec River Superintendent Curt Dimmick says they do on the ground surveys of visitors.

Dimmick says they also measure spending activity.

Dimmick says they would like to see those numbers grow.

The Recreational River is made up of about one hundred miles of free flowing river above and below Gavins Point Dam near Yankton.
