Precarious foundations: irrigation, environment, and social change in the Canadian Pacific Railway's Eastern Section, 1900–1930

Abstract

This paper analyzes the introduction and development of irrigation agriculture in the lower Bow River region, Alberta, Canada. Sponsored by the Canadian Pacific Railroad (CPR) and the Canadian federal government, irrigation promised to transform semi-arid prairie into a densely settled countryside. After 1900, a mixture of policies and practices pioneered elsewhere were deployed to create the largest irrigation project of its kind in North America. Settlers faced difficult economic conditions, however, and fell into conflict with the CPR. The system as a whole experienced a range of environmental changes as irrigation water altered the land and produced new conditions for flora and fauna. By 1930, the irrigation project experienced high levels of settler abandonment and deep fiscal problems. The circumstances of the Bow River case suggest the particular qualities of social and environmental changes initiated by irrigation agriculture in the Canadian prairies, but they also provide the basis to consider comparatively the processes and difficulties attending irrigation expansion in the late nineteenth and early twentieth century world.
