Summary

Dissolved oxygen estimates were generated to help understand how different alternative management scenarios may affect the likelihood of low dissolved oxygen in Glen Canyon Dam releases. The study aimed to examine the effects of different management alternatives on late summer and early fall dissolved oxygen concentrations in Glen Canyon Dam releases. The estimates represent estimates of dissolved oxygen concentration in Glen Canyon Dam releases between August and October of a given year. These estimates were generated using data collected in Lake Powell reservoir as part of a long-term inter-agency water quality monitoring program conducted by the Bureau of Reclamation, the National Park Service, and the U.S. Geological Survey. Specifically, [...]

Purpose

The purpose of these estimates is to inform the National Environmental Policy Act process. These estimates were made to evaluate how water management alternatives proposed under two supplemental Environmental Impact Statements may affect late summer and early fall dissolved oxygen concentrations from Glen Canyon Dam releases. The two data files contain predictions of the average August-October dissolved oxygen concentrations under both No Action and different action alternatives for the supplemental Environmental Impact Statements. We caution the use of these estimates for other purposes; an associated article and data release is forthcoming and will contain more detail on model inputs.
