A new version of an Otty Lake Map was produced in 2021 for residents. This 18" x 24" map is essentially an update of the 2010 map, with island names included, shoals marked, and a 30 m zone noted, as well as a few other changes. Maps are being provided free of charge to paid up OLA members through the area counsellors. The cost for non-members, or for extra copies, is $5.00. The OLA will not be providing an online version until the printed maps are distributed.
