The Brooks Aqueduct is a defunct aqueduct originally built by the irrigation division of the Canadian Pacific Railway Company during the 1910s. The aqueduct stands approximately 8 kilometres south of Brooks, Alberta, Canada. == Overview ==
The main section of the aqueduct spans a 3.2 km valley at an average elevation of 20 metres. The intention of the aqueduct was to irrigate a section of southeastern Alberta and proved to do so for about 30 years. Its original capacity was 900 cubic foot of water per second. In 1969, the Alberta and Canadian governments assumed the responsibility of maintaining the structure under the Prairie Farm Rehabilitation Administration. Although it was thought at first that the governments would rebuild the aqueduct, which had been deteriorating for years, it was ultimately shut down and was left as it was.
