Dundas Falls is a terraced classic cascade on Spencer Creek, after the creek passes under the railway tracks.
The land was owned by the Fisher family and in 1863, John Fisher bought the Gore Paper Mills that stood on the property. In 1929 the mill was demolished to create a site for the school and the waterfall and its channel were constrained to prevent flooding at the school, hence its manmade appearance.
