Modeled economic value of angling and whitewater recreation on the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives (ver. 2.0, July 2026)
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were compiled to predict economic impacts to angling in Glen Canyon and whitewater rafting in Grand Canyon. The objective of our study was to estimate recreation impacts, or changes in consumer surplus, under different Post-2026 EIS alternatives. These data include monthly impacts in nominal 2025 dollars. These data were created for operations at Glen Canyon Dam for January 2027 through December 2060. These data were created by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring and Research Center using mathematical modeling methods. In December 2025, we released tabular data representing the Post-2026 EIS alternative predicted economic impacts to angling in Glen Canyon and whitewater rafting in Grand Canyon. In June 2026, we revised the dataset to include a ninth operational strategy under 400 of the 1200 possible hydrological futures.
