Deep River County Park

About Deep River County Park

The 1,362-acre Deep River County Park is divided into several unique areas. Along Old Lincoln Highway is the historic buildings area, with Wood’s Historic Grist Mill, a wedding gazebo, and the home field of the Deep River Grinders. Along County Line Road is another entrance, along with picnic shelters that are available for rent, a little free library, and a playground. Further north, along Ainsworth Road is Big Maple Lake with fishing opportunities and a lake trail.
