Southern Alberta ScenesMade Possible By Water 12. Forms of Water 13. One of the previous slides was not irrigation-based; which one wasit? 14. Other Forms of Water(with a few solids added) 15. Forms of Water 16. How much water does it take to grow food?Lettuce (500 ml) 11 litresKetchup (30 ml)11 litresWhole Wheat Bread (1 slice)26 litresTomato (125 grams) 30 litresFresh Broccoli (75 grams)42 litresOranges (130 grams)53 litresMilk (250 ml) 180 litresCheese (28 grams) 210 litresEgg (1) 240 litresPlain Yogurt (500 ml) 333 litresChicken (227 grams) 1,250 litresHamburger (113 grams) 2,330 litresSteak (227 grams) 4,662 litres 17. Crops Grown Under Irrigation inAlberta Alfalfa seed, canary seed, caraway seed, carrots,catnip, chick peas, dill, dry beans, dry peas, fababeans, fresh sweet corn, fresh peas, grass seed,hemp, lawn turf, lentils, market garden vegetablesand small fruits, mint, monarda, nursery stock,onions, potatoes, pumpkins, safflower, seedpotatoes, soy beans, sugar beets, sunflower, canola,flax, mustard, barley, grain corn, oats, triticale, wheat(5 kinds), 15 various forages for livestock. 18. Irrigation: variety, assurance, quality, and yield 19. Irrigation Best Practices Irrigation has a major public trust to makethe best use of water licensed by theGovernment (people) of Alberta Use less to produce more Create more opportunities for society 20. Losses that can be reduced Seepage from canals Canal base-flow spills Seepage, evaporation and spills from laterals(small delivery canals) Runoff from gravity flooded fields Non-uniform applications to crops Evaporation of water being applied to crops 21. IRP Program Commitment of Provincial Government andIrrigation Districts to make annualinvestment in improving the irrigation system 75% government: 25% irrigation district Government $24 M per year Districts $8 M per year, plus many investmore of their own funds to speed up therehabilitation; more than $26 M last year 22. Controlling Canal Seepage Losses are 2 to 3 %; membrane liners savewater 23. Controlling Canal Tailout and Bypass Remote and accurate monitoring of flow incanals and laterals (8,000 km) Automated gate operation and remoteactivation of gates to control flows Required notice from farmers to turn wateron and off at the farm 24. SCADA Measuring/Controlling waterdeliveries 25. Systems Must be calibrated Report flows Can adjust flows to match demand Not total automation: flow adjustment muchquicker and quite accurate but still needpersonal experience and verification 26. Benefits of better flow control Reduced diversions Less spill water, i.e., less return flow (waterquality is always lower) 27. 120100Equiv.

PipelinesAdvantages include No seepage No evaporation No water use by phreatophytic plants On/off capability with appropriatevalving 31. 2810 km of Pipelines; 630 km Canals Membrane-Lined 32. Water savings from Pipelines and Canal Rehabilitation Seepage and evaporation losses about 3% 43% of canal system in pipe and lined canal At least 2/3 of greatest problem areas Savings 42,000 ac-ft per year 33. Water savings reduce evaporation,seepage, and leaching on-farm 34. Upping Efficiencyof On-Farm Water Application 35.

Efficiency Investment Results Total $$$ spent by Government of Canada,Government of Alberta, and the IrrigationDistricts in collaborative programs equals$1.02 billion; farmers $0.6 billion Canadas irrigation, of which Albertaconstitutes over 60%, is ranked 2nd in theworld for its efficient systems (for countrieswith as much or more irrigated area) 37. Efficiency Investment Results Since 1976, irrigation farmers in districtsirrigate 46% more land and divert 10% lesswater. 38. 14.012.0 Productivity Index (kg/m3)10.0 8.0 6.0 4.0 2.0 0.0 19801982 19841986 19881990 19921994 19961998 20002002 20042006YearIncreasing productivity of potatoes, sugar beets, and soft white wheat 39. Riparian Health 40. Riparian Health 41. Social Commitments AIPA Human Use Declaration: communities(people) will be given priority over irrigationin times of drought Irrigation districts will make water availablein the SouthGrow region for communitiesand economic development 42. Climate Change Climate change is a big unkown Dr. Stephan Kienzles research indicates wemay have as much moisture fall in themountains, but that the form and timing willchange: likely more rainfall and less snow, somore rapid peaking of rivers and more rapidrecession 43. When you are thirsty,you find a way to adapt,and get water
