Broderick Reservoir is a reservoir about 11 kilometres (6.8 mi) south-southeast of Outlook in the Canadian province of Saskatchewan in the Rural Municipality of Rudy No. 284. Broderick Reservoir was built in 1967 as part of South Saskatchewan River Project. That project involved the building of aqueducts and a series of reservoirs to supply water for irrigation, consumption, and industry originating at Gardiner Dam at Lake Diefenbaker. Broderick is the first reservoir in the series. Downstream reservoirs include Brightwater Reservoir, Indi Lake, Blackstrap Lake, Bradwell Reservoir, Zelma Reservoir, and Dellwood Reservoir.
