Milne Dam spans the Rouge River near the southern edge of Markham, originally built in the 1800s to power a gristmill operated by the Milne family. The current concrete-and-steel arc dam, one of the first of its kind in Canada, was constructed by Archie Milne and now serves as a flood control structure managed by the Toronto and Region Conservation Authority. A fishway added in 2005 allows salmon and trout to bypass the dam and reach upstream spawning grounds, restoring access to over 45 kilometres of river habitat.
