In 1972, Larry and Ron Johnson opened Johnson Brothers Marina at the 47MM, Lake Road 135-3 (now known as Cup Tree Road). The Hwy 5 location was opened only five years later in 1977. The marina location, on Cup Tree Road, is a full service marina offering gas dock and dry boat storage. The Hwy 5 location also offers dry boat storage and one of the largest parts and accessory inventories in the lake area! Currently, Ron and Sue Johnson manage the marina located off of Cup Tree Road (Lk Rd. 135-3) and Larry and Judy Johnson manage the Hwy 5 location. Bill (Larry and Judy's son) is the parts manager at the highway store.
