The Water Tower Museum is located in Anzac Park, adjacent to the Visitor Information Centre and town swimming pool. The museum is now housed in what was once the town's main concrete water tower.
The building has three floors of display area and an observation deck on the roof that provides panoramic views of Gunnedah and the surrounding district.
The collection includes local history information, mural and displays of the first explorers, household memorabilia, memorabilia from major world conflicts, and local school history.
