Biological Assessments and Opinions
On this page you will find a chronological listing of Biological Assessments and their accompanying Biological Opinions for projects in the Interior Region 7 – Upper Colorado Basin.
The Endangered Species Act requires that any federal agency proposing an action that may have an effect on an ESA-listed fish – issuing a permit, spending money, taking a direct action on fish habitat – consult with the act’s regulatory agencies’, the U.S. Fish and Wildlife Service or NOAA Fisheries.
Reclamation will complete a biological assessment on potential effects to the fish or its habitat and submit it to the regulatory agency. The regulatory agency then renders a Biological Opinion back to Reclamation.
The intent of a Biological Opinion is to ensure that the proposed action will not reduce the likelihood of survival and recovery of a ESA-listed species. A Biological Opinion usually also includes conservation recommendations that further recovery of the specific ESA-listed species.
