Frequently Asked Questions
What crops define Umatilla County farming and what makes the county’s agricultural output significant?
Umatilla County ranks among Oregon’s top agricultural counties by both acreage and production value. Soft white winter wheat is the dominant dryland crop on the Palouse-adjacent slopes above Pendleton and Weston.
In the irrigated Hermiston area, the county produces potatoes at a scale significant for the Pacific Northwest processing market, with large farms supplying Lamb-Weston and other major potato processors. Sweet corn is grown extensively for canning and freezing operations. The county is also Oregon’s leading producer of watermelons, which thrive in the hot Hermiston summers. Onions, asparagus, and certified vegetable seed crops round out one of the most diverse agricultural portfolios in the Pacific Northwest.
How do Umatilla Project assessments work for Umatilla County irrigated farms?
Umatilla County irrigated farms served by the Umatilla Project pay annual operation and maintenance (O&M) assessments to the Bureau of Reclamation per irrigated acre. These assessments cover system maintenance, pumping costs, and capital replacement for delivery infrastructure. Assessment rates vary by delivery unit and proximity to pumping stations.
In addition to O&M assessments, farms have repayment obligations for the original federal investment in project infrastructure, though many original repayment contracts have been completed. When evaluating an irrigated Umatilla County farm, the annual assessment obligations must be factored into the operating cost calculation alongside the obvious advantages of reliable water delivery.
What makes Umatilla County wheat ground different from wheat land in neighboring Morrow and Gilliam counties?
Umatilla County dryland wheat ground, particularly in the higher-elevation eastern portion of the county around Weston, Milton-Freewater, and the Tollgate area, receives greater annual precipitation than the drier lower-elevation Columbia Plateau counties to the west. Annual rainfall of 14 to 20 inches in the upper county elevations supports higher yields, better organic matter accumulation in the deep volcanic soils, and more consistent cropping options compared to the 10 to 14 inch zone in Morrow and Gilliam.
The upper county Palouse-type soils also support winter peas and lentils in rotation with wheat on some operations. This precipitation and soil quality advantage explains why Umatilla County per-acre prices run $200 to $700 higher than comparable acreage in lower-rainfall neighboring counties.
What are typical cash rents for Umatilla County farmland and how are leases structured?
Umatilla County cash rents vary significantly by land type. Irrigated project-served ground in the Hermiston area leases for $180 to $280 per acre annually for row crop production. Dryland wheat in the high-precipitation Weston and Milton-Freewater area runs $70 to $110 per acre. Mid-county dryland ground near Pendleton runs $50 to $80 per acre.
Dryland leases are typically structured as cash per acre for the entire farm with the tenant absorbing all production inputs and risks. Irrigated leases may include separate assessments for the water charges, which are passed through to the tenant. Oregon State University Extension’s annual land values report provides county-specific benchmarks for lease negotiations.
