Potato harvest is underway in eastern Idaho with growers reporting yields as much as 20% below last year, smaller tuber sizes, and reduced acreage following a statewide drought declaration in April. The Idaho Department of Water Resources issued that declaration after a dry spring, and high summer temperatures — with stretches above 90°F for six consecutive weeks — compounded the damage. Total Idaho potato acreage fell roughly 5% year over year to around 121,400 hectares, with many growers planting less or switching to lower-water crops entirely.
The supply tightening is already pushing potato prices higher, though rising diesel costs during harvest are eating into grower margins. Storage reservoirs in the Upper Snake River basin were reported at all-time lows as of early October, raising immediate questions about water availability heading into the 2027 planting season. One grower said bluntly: "We're not going to have much water left in our bucket for 2027."
For buyers with potato programs tied to Idaho — including fresh russets, reds, and yellows — this is a situation worth watching through winter. Tightened supply combined with elevated freight costs could put upward pressure on pricing further into the season, and reduced 2027 planting could extend the impact.
