To Whom It May Concern: The proposed designation of critical habitat for the conservation of Oregon chub (Oregonichthys crameri) as published in the Federal Register on 10 March 2009 is well considered and well presented. The document accurately describes the habitat requirements for this species, the historical changes in Willametter River basin ecology and flow regimes, and the underlying reasons for this species endangered status. The principal research and survey findings by the Oregon Department of Fish and Wildlife and Oregon State University are well reflected in the document. Stemming from the understanding of Oregon chub life history and habitat requirements, the identification of four Principal Constituent Elements for Oregon chub critical habitat on p 10417 are appropriate and well-supported by our understanding of this species. Similarly, the application of these PCEs to identify areas where these features are found is also well-reasoned and supported by the scientific research and surveys. The threats to Oregon chub and its habitat are accurately represented in the discussion of special management considerations or protections on p 10418. The Service is to be commended for preparing a thorough and articulate discussion of the habitat needs, and the threats to important habitat, of the Oregon chub. This discussion fully supports the careful selection of the proposed critical habitat areas.
