Progress in the Amuri Basin

By Kris Polly

This month, we speak with Sara Black, the CEO of Amuri Irrigation Company, which manages three irrigation schemes in New Zealand’s Amuri basin. The company has launched an ambitious farmer-led project to find environmental risk solutions to create a more sustainable future for farming in the basin. In our interview, we hear more about how the company works with farmers to optimize irrigation and nutrient management on farms and how it’s developing a risk-based resource management system to find the solution that best fits individual farms.

The Friant Water Authority facilitates the delivery of over 1 million acre-feet of water a year from Friant Dam to 32 California water agencies. Unfortunately, groundwater overdraft has caused ground subsidence severe enough to impede the functioning of its Friant-Kern Canal. Demonstrating that the American can-do spirit is alive and well, the water authority is executing the Middle Reach Capacity Correction Project, phase 1 of which included the construction of a parallel canal along one affected section. We hear more in our detailed and informative interview with Friant CEO Jason Phillips.

Then, we speak with Bert Bryan, the manager of the 100‑plus-year-old Walker River Irrigation District in western Nevada. As we hear from Mr. Bryan, the district’s service area is characterized by a patchwork of different types of water rights as well as by a complicated interplay of environmental flow requirements and agricultural uses. The district is also carrying out a variety of modernization and efficiency projects.

Next, we speak with John Thom and Neal Schlautman, respectively the vice president and the engineering manager of T‑L Irrigation Company, about the company’s new Edge Controller, an award-winning device that centralizes control functions at the end tower of a center pivot.

Dan Preissler is a Nebraska farmer who recently started using Sentinel Fertigation’s N‑Time solution. We interview him about his experience and the nitrogen-saving results he’s seen.

Munro is a Colorado-based manufacturer of pumps, pump controls, pumping stations, and related products that also runs a general industrial distributor. We interview Katie Powell, a third-generation member of this family-owned company who now serves as its president, about its high-quality, custom-built solutions.

Finally, we speak with Dr. Michele Reba, a research hydrologist and the lead scientist at the Agricultural Research Service’s Delta Water Management Research Unit, based in Jonesboro, Arkansas. She fills us in on the research unit’s work and its payoff for the major irrigated cotton, rice, and soybean production in the region.

With research, new technologies, major construction projects, small-but-steady system modernization work, long- term sustainability efforts, and top-notch products, irrigated agriculture is improving every day. Each agency, district, company, and research center has its own role to play in this constant improvement. We hope you enjoy reading.
