Whether your boat is 12 or 90 feet long, we have the accomodations for you. Mid River, being family owned and operated for the past 30+ years, has watched generations grow from children swimming and kneeboarding, to teens wakeboarding, and then to young adults getting married right here at the marina. Whatever your family boating needs are, Mid River will strive to make the marina your home away from home. Thank you for visiting our website. We hope you will take the time to come visit us personally and see why many have come to call Mid River their home away from home.
