As of February 26, Lake Oroville levels have decreased to 843 feet, 58 feet below the reservoirs’s maximum level. Outflow remains at 50,000 cubic feet per second, consistent with DWR’s established plan to manage lake levels. Repair work continues 24 hours a day on the area below the spillway, access roads, and various eroded areas created by emergency spillway runoff.
  • Caltrans will begin emergency work on Canyon Drive as early as Tuesday, February 28. This work will take approximately 7-10 days and the road will be restricted to single lanes with a pilot car guiding traffic.
  • Construction crews are installing foundations for check structures that would slow water flows should the emergency spillway be required.
  • Barges have been assembled and equipment is being staged for debris removal below the flood control spillway in the diversion pool.
DWR is actively monitoring the status of the dam, spillways, Hyatt Power Plant, related structures, and progress of repair activities. For more information, follow us on Twitter or Facebook. Additional details can also be found in our press releases and on our Oroville Spillway Incident webpage.
