Summary

These data were compiled for/to modeling efforts for U.S. Bureau of Reclamation National Environmental Policy Act (NEPA) analyses for the Colorado River in Grand Canyon, Arizona. Objective(s) of our study were to create revised monthly Lake Powell elevations and outflows from Bureau of Reclamation Colorado River Mid-term Modeling System (CRMMS) traces that incorporate the alternatives in the sEIS documents and indicate when potential actions may occur and how that changes water movement and storage. These data represent monthly hydrologies for Lake Powell: inflow, outflow, and elevation forecasts for 2024-2027, as well as volumes of water in outflows for different water mangement strategies in NEPA supplemental environmental impact [...]

Purpose

The purpose of these data are to provide estimates of monthly Lake Powell inflows, outflows, and elevations, as well as, timing and magnitude of potential supplemental environmental impact statement (sEIS) actions. These data were created to fullfill NEPA analysis requirements about potential impacts to resources.
