The Stave River is a tributary of the Fraser, joining it at the boundary between the municipalities of Maple Ridge and Mission, about 35 kilometres (22 mi) east of Vancouver, British Columbia, Canada, in the Central Fraser Valley region.Blocked since the 1920s by two dams built by the BC Electric Railway at Stave Falls and one at Ruskin, the only free-flowing parts of the Stave today are the 3 kilometres (1.9 mi) between Ruskin Dam and the Fraser and the 45 kilometres (28 mi) from its source in Garibaldi Provincial Park to the head of Stave Lake.
