The Department of Natural Resources (DNR) announced that this year’s wild rice crop yield in northern Wisconsin is low, continuing a pattern of lower yields over recent years. Wild rice crops have been affected by heavy rainfall and powerful storms this year, contributing to an 18% decline in the wild rice crop compared to last year.

“The 2025 season has brought a mix of conditions, including several notable storm systems,” said Kathy Smith, Ganawandang manoomin (which means she who takes care of wild rice), with the Great Lakes Indian Fish & Wildlife Commission. “A fast-moving windstorm in mid-June produced widespread wind damage and heavy rainfall across the upper Midwest. In late June, some areas saw 6-7 inches of rain in a short period, contributing to temporary high-water levels on seepage lakes.”

Using satellite-facilitated remote sensing technology, the commission was able to determine the 18% decline in the wild rice crop. A DNR press release notes that these technologies do not provide insights into local wild rice production, bed densities, or seed production. Early scouting reports help fill in the gaps, showing a “mixed bag of production,” the agency stated,  “with some top-producing lakes seeing declines in the crop from last year, while others appear to be rebounding.” 

Wild rice harvesting is open to all Wisconsin residents with a wild rice harvester license. The crop provides nutritious, naturally grown food to people across the upper Midwest. Wild rice also holds an important cultural place for indigenous tribal communities. Around late August through mid-September, the rice reaches maturity. Jason Fleener, a DNR wetland habitat specialist, stresses that it’s important to wait to harvest the rice until it falls with relatively gentle strokes or knocks from  ricing sticks. If no rice falls, then it’s best to wait a few more days before attempting to harvest. 

Harvesting immature beds can negatively affect the overall harvest, as well as the long-term sustainability of the rice. Besides climate effects, human activity such as boating (which creates waves that uproot growing rice plants) can also harm the crop.
