The Final Mile, Ep 4: Using Water Wisely with John Kolk and Chris Gallagher

Why It Matters

Efficient irrigation safeguards a quarter of Alberta’s agricultural output while navigating growing water scarcity, making technology and research investments critical for the province’s economic and food‑security future.

Key Takeaways

• Irrigation drives 28% of Alberta’s ag GDP from just 4% farmland.
• Farmers adjust rotations and adopt low‑pressure pivots amid water uncertainty.
• Districts upgrade canals to pipelines, boosting conveyance efficiency.
• Automation and AI aim to match water delivery with crop demand.
• Research needed to link genetics, climate, and irrigation performance.

Summary

The Final Mile episode spotlights irrigation’s transformative role in southern Alberta, featuring farmer John Kolk and Lethbridge Northern Irrigation District GM Chris Gallagher. They discuss how a vast network of 8,000 km of canals and 57 reservoirs underpins 1.7 million acres, delivering just 4% of the province’s cultivated land yet contributing roughly 28% of agricultural GDP.

Key insights include farmers reshaping crop rotations—favoring pulses, limiting double‑cropping, and deploying low‑pressure and variable‑rate pivots—to hedge against tighter water supplies. District managers allocate water based on snowpack, reservoir levels, and real‑time updates, balancing early-season certainty with seasonal adjustments. Technological upgrades, such as lining canals, burying pipelines, and automating flow controls, have markedly improved conveyance efficiency.

John cites a jump from 50 bushels of barley on 28 inches of flood water to 140 bushels of corn on 10‑12 inches thanks to genetics, management, and pivot tech. Chris highlights an AI‑driven pilot project that integrates crop demand models with irrigation scheduling to deliver the right water at the right time, while both note the need for deeper research linking plant genetics, climate, and irrigation practices.

The conversation underscores that efficiency gains are essential for sustaining productivity amid climate variability. Continued investment in infrastructure, automation, and public‑good research will bolster resilience, protect water allocations, and preserve the sector’s outsized contribution to Alberta’s economy.

Original Description

Irrigation has long been a cornerstone of southern Alberta agriculture, but tighter water supplies and rising complexity are reshaping how producers and districts manage every drop.

In this episode of the Final Mile podcast, Shaun Haney speaks with John Kolk of Kolk Farms and Chris Gallagher, general manager of the Lethbridge Northern Irrigation District (LNID), about how technology, infrastructure, and decision-making are evolving under increasing pressure.

For Kolk, recent seasons have forced a sharper focus on efficiency and risk. Crop rotations are being adjusted, and investments in tools like low-pressure pivots and variable rate irrigation are helping stretch limited supplies. “We moved from a space where there was 24 inches of water available… now we’ve moved to limits,” he says, noting that constraints are driving better measurement and management.

At the district level, Gallagher says balancing supply and demand has become more complex. Allocation decisions depend on snowpack, reservoir levels, and in-season weather, all while giving farmers enough certainty to plan. “We don’t want to over promise and under deliver on the volume of water that’s available,” he explains.

Both point to significant gains in efficiency—from canal-to-pipeline conversions to on-farm automation—but acknowledge that future progress will depend on integration. Linking farm-level technology with district systems, alongside improved modelling and data use, represents the next step.

Despite water constraints, irrigation continues to punch above its weight economically, supporting high-value crops and contributing disproportionately to Alberta’s agri-food GDP. The challenge now is protecting that value while adapting to a more variable and tightly managed water future.
