The Brooks Aqueduct is a defunct aqueduct, historic site and museum originally built by the irrigation division of the Canadian Pacific Railway Company during the early 1910's located in Southern Alberta, Canada. The aqueduct was intended to irrigate a section of southeastern Alberta by diverting water east from Lake Newell from 1914 to 1979, and is located approximately 8 kilometres south of the City of Brooks. The main section of the aqueduct spans a 3.2 km valley at an average elevation of 20 metres. The structure has been designated a National Historic Site with an interpretive centre constructed nearby for tourists.
