This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Notice of document availability.
To further the recovery of humpback chub (Gila cypha), bonytail (Gila elegans), Colorado pikeminnow (formerly named Colorado squawfish; Ptychocheilus lucius), and razorback sucker (Xyrauchen texanus), we, the Fish and Wildlife Service announce the availability of draft recovery goals for these endangered fishes of the Colorado River Basin. This information will serve as a supplement and amendment to the respective existing recovery plans for each species. The draft recovery goals for each species provide objective, measurable recovery criteria for downlisting and delisting that identify levels of demographic and genetic viability needed for self-sustaining populations and site-specific management actions/tasks needed to minimize or remove threats. We solicit review and comment from agencies and the public on these draft recovery goals. Reviewers should pay particular attention to the application of existing demographic and genetic data in the development of minimum viable population (MVP) standards and the downlisting and delisting monitoring periods associated with each species.End Preamble Start Supplemental Information
The purpose of these supplements and amendments are to describe site-specific management actions/tasks; provide objective, measurable recovery criteria; and provide estimates of the time required to achieve recovery of each of the four endangered fish species. The recovery goals for the humpback chub, razorback sucker, and bonytail are identified by two recovery units, upper basin (above Glen Canyon Dam, Arizona) and lower basin. Recovery of the Colorado pikeminnow is currently considered only for the upper basin. Downlisting and delisting criteria by listing factors and management actions, as well as demographic criteria, are presented for populations of each species within recovery units. In addition, updated life-history information, statistical criteria for monitoring, and estimated time to achieve downlisting and delisting requirements are also identified. These serve as supplements and amendments to the recovery plans by providing more Start Printed Page 47034specific objective and measurable criteria to recover each of the four fish species.
Copies of the Draft Recovery Goals will be mailed to interested parties upon request. The documents are also available (in *.pdf format) for viewing and downloading at: http://www.r6.fws.gov/crrip/rg.htm. Make requests and mail comments to the Director at the address below. You may submit comments by sending electronic mail (e-mail) to: colorivgoals @ fws.gov.
The agency must receive comments on or before October 25, 2001.
