Aqueduct - Giant Centipede of the Prairie

Called River in the Sky. It even had fish. Built by Canadian Pacific Railway in 1912-1914 to turn rangeland into farmland. It was 31 km long reinforced concrete carrying water from the Bow River. The main engineering innovation was an inverted siphon to run the water under the CPR mainline as the aqueduct wasn't high enough for the trains to get under. It never operated efficiently and was replaced by 1979 by the present day canal, alongside, which also goes under the CPR mainline.

The siphon is a short walk east of the parking lot, playground, and visitor centre.

Bypassed by a better, faster water system, disconnected parts of the aqueduct still stand through the area.
