Butte City Bridge Project -

Starting March 14, 2022, CalTrans began construction on the new Butte City Bridge at the Sul Norte and Codora Units.  A new bridge and causeway is being constructed adjacent to the existing structures, after which the old structures will be demolished.  The Sul Norte and Codora Units will continue to be open to the public through the current parking lot, although road and trail access may be temporarily re-routed to accommodate construction activity.  The SAFETY ZONE adjacent the bridge has been expanded by 150 feet during the construction project - please follow all signs in the field.

Brush Control Project - from late November 2022 through February 2023, a brush control project will be implemented on the Pine Creek, Drumheller North, Drumheller Slough, Afton, Packer and Codora units and equipment and disturbance may be encountered during this time period.

Dairy Fire burn area is re-opened to public access - The area that was closed in June 2021 due to the Dairy Fire has been re-opened after hazard tree removal has been completed.  The Dairy Fire affected the southern portion of the La Barranca Unit, the western portion of the Todd Island Unit, and the northern portion of the Mooney Unit.  Please continue to use caution when visiting this area as tree health may continue to change over the upcoming months.

      Our Organization

      National Wildlife Refuge System Improvement Act of 1997:The NWRS Improvement Act defines a unifying mission for all refuges, including a process for determining compatible uses on refuges, and requiring that each refuge be managed according to a CCP. The NWRS Improvement  Act expressly states that wildlife conservation is the priority of System lands and that the Secretary shall ensure that the biological integrity, diversity, and environmental health of refuge lands are maintained. Each refuge must be managed to fulfill the specific purposes for which the refuge was established and the System mission. The first priority of each refuge is to conserve, manage, and if needed, restore fish and wildlife populations and habitats according to its purpose.

      Our Species

      Several threatened, endangered, and sensitive species can be found on the Sacramento River Refuge including Chinook salmon, Valley elderberry longhorn beetle, yellow-billed cuckoos, Swainson's hawks, and bank swallows.
