Trout Reduction Program

Actually, this is good management: Grand Canyon News Release Release date: Immediate Contact(s): Maureen Oltrogge Phone number: 928-638-7779 Date: August 31, 2006 National Park Service Announces Availability of Environmental Assessment/Assessment of Effect for Bright Angel Creek Trout Reduction Project Grand Canyon, Ariz. – Grand Canyon National Park Superintendent Joseph F. Alston today announced the availability of an Environmental Assessment/Assessment of Effect (EA/AEF) for the Bright Angel Creek Trout Reduction Project. The EA/AEF will be available for public review and comment for a period of 30 days. This EA/AEF evaluates a No Action Alternative (Alternative A), and an action alternative (Alternative B) that proposes mechanical removal of non-native fish species (primarily trout) from Bright Angel Creek in Grand Canyon National Park. The dual purposes of the project are to benefit endangered humpback chub (Gila cypha) and other native fish species in the mainstem Colorado River, and to restore and enhance, to the extent possible, the native fish community that once flourished in Bright Angel Creek. To meet these objectives, the preferred alternative, Alternative B, proposes to reduce populations of non-native brown trout and, coincidentally, rainbow trout in Bright Angel Creek by means of a weir (fish trap) installed near the mouth of the creek. Trout would also be removed incidental to fish population surveys using electrofishing. Alternative B is based on a feasibility study conducted in November 2002 through January 2003, which determined that using a weir was successful at removing trout from Bright Angel Creek, and a non-native fish population survey in March 2006 which determined the effectiveness of using backpack electrofishing as a management tool in Bright Angel Creek. All actions described in the preferred alternative are consistent with the Park’s 1995 General Management Plan and related park documents. The proposed action would begin as early as November 2006 and continue for five years, with annual monitoring and evaluation of the project.
