The Keystone Historical Society and Museum holds the historical stories of cities now underwater due to the construction of Keystone Lake. Built in the 50s and 60s, Keystone Lake was necessary for flood management in the area. The city of Keystone among other neighboring towns were evacuated and swept under water in the making. The Mannford Museum preserves the history many were afraid of losing. This educational museum is great for residents of the area, curious families, schools, and history enthusiasts alike.
