Temporarily Closed

  • Packer Unit Boat Launch (Sacramento River NWR): due to a downed tree across the boat launch, visitors will not be able to launch boats into Packer Lake until staff are able to move or remove the downed tree.

All other refuges and refuge units are open. Check out seasonal recreation opportunities on our Auto Tours, Trails & Bicycling page or our Maps, Directions & Brochures page.

*Before calling the refuge for updates, please review this section of our website or our social media pages. Any new information will be posted here and to our Facebook  and Instagram promptly. Areas are subject to closure without notice. Please use extreme caution when driving the refuges, as flooding can occur without warning and road shoulders are soft and will not support your vehicle.
