McGregor Lake is an elongated () reservoir in Southern Alberta. McGregor Lake was created in 1920 by the completion of two dams bracketing Snake Lake in Snake Valley. It is situated southeast of Calgary in the Vulcan County. The reservoir is part of the Carseland-Bow River Headworks System that is owned and operated by Alberta Environment and delivers water to the Bow River Irrigation District. McGregor Lake is in the Oldman River drainage basin, but most water in it arrives via canals from the Bow River. The reservoir was built by British-owned Canada Land and Irrigation Company and named after J. D. McGregor, the company's Canadian manager who became Lieutenant Governor of Manitoba in 1929. ==History== The reservoir occupies part of the Snake Valley, prehistorically, a thoroughfare for members of the Blackfoot Confederacy. The first European settlers arrived mid-nineteenth century. Ranching was well established by the 1880s. Shortly after, homesteading and farming were prevalent in the valley. The rich soil and dry climate led to an interest in irrigation. Construction began in 1909 on a major reservoir. Two dams were built - one in the north near Milo, Alberta and a second, south dam. McGregor Lake was created when the Canada Land and Irrigation Company completed the South and North McGregor dams. Some of the water in the reservoir comes from the Old Man River, but a canal was also constructed to bring water from the Bow River near Carseland. Construction was a ten-year project, the reservoir began filling in 1920. It was administered as a private company until 1950, when the federal Prairie Farm Rehabilitation Administration assumed control and modified the dam into a zoned earthfill structure from its previously homogeneous state. In 1973, McGregor Lake and its control structures were transferred to Alberta Environment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「McGregor Lake」の詳細全文を読む スポンサード リンク
