The U.S. Army Corps of Engineers and a regional irrigators association differ by a wide margin in their estimates of how many irrigated acres would potentially be impacted by removal of the lower Snake River dams.

The Corps says it’s about 48,000 acres, citing its 2020 Columbia River Systems Operations environmental impact statement.
