Subject Keywords Irrigation -- British Columbia -- Vernon irrigation district.
Abstract: The Okanagan Valley is an important agricultural area in south-central British Columbia. Due to the low annual precipitation and a high rate of evapotranspiration, irrigation is necessary for the production of most crops. Since water shortage problems in the valley are likely to arise in the future, since irrigation accounts for over 90% of the consumptive use of water in the valley, and since data on the actual irrigation operation is sparse, a detailed study was made of one district. Vernon Irrigation District, the largest district in the Okanagan Basin, was selected for detailed study. Its distribution system has recently been modernized. The history of the development of the district is outlined and the old system and the way in which it operated are described. The reasons for selection of the new system, the criteria used in its design, and the way in which the new system now operates are described. Particular attention is paid to scheduling—the timing of the application of water to the crops—since this offers one of the best opportunities for the conservation of water in the future. Minor conflicts with other users of the water resource are identified and suggestions given for minimizing such conflicts.
