The district entered into an agreement in 1919, with the A.R. & I. Co. for the annual delivery of 41,938 cubic decametres of water to irrirrigate 6,880 hectares. This water was to be delivered through works originally constructed by the A.R. & 1. Co. The new 37-kilometre canal from Chin Coulee to Taber cost $272,000 and was completed in 1920. In operation it was found there was a surplus of water available, and in 1929, a further 3,966 hectares were added to the project. The cost of the land and extended works was $33,000. Following the enlargement of the St. Mary River Development canal system, a further 4,047 hectares of irrigable land were added to the district in 1952.
Water is supplied to the district from turn-outs on the St. Mary main canal. The district has 112.6 kilometres of canals with capacities greater than 1.5 cubic metres per second, and has two internal storage reservoirs, with a combined capacity of 11,623 cubic decametres. By 1979, development of lands within the district had increased the irrigated area to 25,300 hectares.
