Crops Grown Under Irrigation in Alberta• Alfalfa seed, canary seed, caraway seed, carrots, catnip, chick peas, dill, dry beans, dry peas, faba beans, fresh sweet corn, fresh peas, grass seed, hemp, lawn turf, lentils, market garden vegetables and small fruits, mint, monarda, nursery stock, onions, potatoes, pumpkins, safflower, seed potatoes, soy beans, sugar beets, sunflower, canola, flax, mustard, barley, grain corn, oats, triticale, wheat (5 kinds), 15 various forages for livestock.

Irrigation: variety, assurance, quality, and yield

Irrigation Best Practices• Irrigation has a major public trust – to make the best use of water licensed by the Government (people) of Alberta• Use less to produce more• Create more opportunities for society

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

IRP Program• Commitment of Provincial Government and Irrigation Districts to make annual investment in improving the irrigation system• 75% government: 25% irrigation district• Government $24 M per year• Districts $8 M per year, plus many invest more of their own funds to speed up the rehabilitation; more than $26 M last year

Controlling Canal Seepage• Losses are 2 to 3 %; membrane liners save water

Controlling Canal Tailout and Bypass• Remote and accurate monitoring of flow in canals and laterals (8,000 km)• Automated gate operation and remote activation of gates to control flows• Required notice from farmers to turn water on and off at the farm

SCADA – Measuring/Controlling water deliveries

Systems• Must be calibrated• Report flows• Can adjust flows to match demand• Not total automation: flow adjustment much quicker and quite accurate but still need personal experience and verification

Benefits of better flow control• Reduced diversions• Less spill water, i.e., less return flow (water quality is always lower)

Pipelines

Pipelines Versus Open Chanels

PipelinesAdvantages include• No seepage• No evaporation• No water use by phreatophytic plants• On/off capability with appropriate valving

2810 km of Pipelines; 630 km Canals Membrane-Lined

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

Water savings – reduce evaporation, seepage, and leaching on-farm

Upping Efficiencyof On-Farm Water Application

Efficiency Investment Results• Total $$$ spent by Government of Canada, Government of Alberta, and the Irrigation Districts in collaborative programs equals $1.02 billion; farmers $0.6 billion• Canada’s irrigation, of which Alberta constitutes over 60%, is ranked 2nd in the world for its efficient systems (for countries with as much or more irrigated area)

Efficiency Investment Results• Since 1976, irrigation farmers in districts irrigate 46% more land and divert 10% less water.

Riparian Health

Social Commitments• AIPA Human Use Declaration: communities (people) will be given priority over irrigation in times of drought• Irrigation districts will make water available in the SouthGrow region for communities and economic development

Climate Change• Climate change is a big unkown• Dr. Stephan Kienzle’s research indicates we may have as much moisture fall in the mountains, but that the form and timing will change: likely more rainfall and less snow, so more rapid peaking of rivers and more rapid recession

When you are thirsty,you find a way to adapt,and get water
