3 ALBERTA IRRIGATION INFORMATION 217 BASIN WATER MANAGEMENT SECTION IRRIGATION AND FARM WATER BRANCH JULY 218 The purpose of this booklet is to provide a statistical overview of irrigation information and data relating primarily to the thirteen irrigation districts situated in Alberta, but also includes information about irrigation across the whole province. The majority of the annual data is provided by the irrigation districts. This report is prepared by Alberta Agriculture and Forestry. For more information, please contact: Andrea Gonzalez, Alberta Agriculture and Forestry Agriculture Centre Lethbridge, Alberta T1J 4V6 Telephone (43) andrea.gonzalez@gov.ab.ca For an electronic version of this report and additional information visit: Website: Select: Agriculture Soil/Water/Air Irrigation Facts & Figures Government

18 Equivalent Depth (mm) Figure 8. Irrigation Districts Gross Diversion Equivalent Depth Note: Irrigation district equivalent depth is the annual gross diversion of water (into the works of all 13 irrigation districts), divided by the area actually irrigated. However, this depth also includes water used for net gains in reservoir storage, water diverted for other uses such as domestic, municipal, other agricultural, industrial, recreational and habitat enhancement purposes. Productivity Index (kg/m 3 ) Figure 9. Irrigation Districts Water Use Productivity Note: Commodity yield per unit area divided by the volume of irrigation water diverted per unit area provides a measure of productive output per unit of irrigation water used. The historical yields of sugar beets (as reported by the Alberta Sugar Beet Growers), the historical yields of potatoes (as estimated by the Potato Growers of Alberta) are tallied and then divided by the respective reported annual gross water diversions to the 13 irrigation districts to derive a Productivity Index.

Glossary Gross Diversion - Volume of water diverted from a lake, reservoir or the river system by irrigation districts. Net District Storage Change - Net volume of water removed from internal irrigation district reservoirs for use. A negative number within brackets, indicates a net increase in reservoir storage volume over the irrigation season. Total District Use - Total volume of water used from diversion and storage. Delivered for Irrigation - Net volume of water supplied for irrigation purposes. Delivered for Other Use - Volume of water supplied for other uses including municipal domestic, other agricultural, industrial, and environmental uses. Canal & Reservoir Seepage - Water lost from reservoirs and through delivery system from seepage. Canal & Reservoir Evaporation - Water lost from evaporation from the surface of irrigation district canals and reservoirs. Return - Volume of water returned to the river system. Total District Operations - Total volume of water used for irrigation districts operations comprised of water delivered for irrigation, other use, seepage and evaporation, and water returned.
