Publication of Environmental Assessments for High Flow Experiment Protocol and Non-native Fish Control

The Department of the Interior, acting through the Bureau of Reclamation, is proposing to develop and implement a protocol for high-flow experimental releases from Glen Canyon Dam to better determine whether and how sand conservation can be improved in the Colorado River corridor downstream from Glen Canyon Dam, and is also proposing to conduct research, monitoring and specific actions to control non-native fish in the Colorado River downstream from Glen Canyon Dam in an effort to help conserve endangered fish.

Two environmental assessments (EA) have been prepared to analyze and disclose the environmental effects of the proposed actions. The EAs are available on our website at the links below. Printed copies of the EAs are also available at the Bureau of Reclamation, Upper Colorado Regional Office, 125 South State Street, Room 7218, Salt Lake City, Utah 84138.

We have also included several related documents, including: the Biological Opinion recently received from the U.S. Fish and Wildlife Service, which covers both proposed actions; Science Plans for both actions prepared by the U.S. Geological Survey; and our determinations of eligibility and adverse effect for National Historic Preservation Act 106 compliance for both actions. All of these documents are provided at the link below.
