With the Growing water traffic, the need arose of a marker in the river entering the locks, and so the lighthouse was built. The boat captains signaled their arrival to the lockmaster by three blasts on the whistles they passed the lighthouse. Mrs. Nicholson, who lived nearby, lit a lamp every evening.
This was demolished years later, but in 1995, the Magnetawan River Heritage Association had a replica built on the original site. A reproduction of this historic lighthouse is located above the dam and locks in Lake Cecebe. The Lighthouse is visible from the “Dam Trail” on the Island in Magnetawan or from Highway 520 east of the village.
