In the early 1950s, irrigation was extended to the Bow Island area, and the town doubled in population. Bow Island is surrounded by 110,000 acres (445 km²) of highly productive lands. Some of the most modern irrigation systems in the world are located in the area; the first pivot and linear sprinkler systems in Canada were erected in the Bow Island area. A completely automated distribution system was installed in 1982 by the St. Mary River Irrigation District (SMRID), and it serves an area of 5,000 acres (20 km²). The system is known as the Lateral 12 System and has been toured by groups from around the world.
