Oroville Field Division Starts Controlled Burns in Lake Oroville’s McCabe cove
Every spring, Oroville Field Division (OFD) maintenance crews collect floating debris carried into Lake Oroville by winter rains from the three forks of the Feather River. Logs, branches and other floating debris is secured and towed to a remote cove on the Feather River’s South Fork arm of the lake. As summer water deliveries lower lake levels, the floating debris is deposited on the shoreline. After the first rains of the season, OFD’s maintenance crews pile the logs into small piles for burning. The public is advised to use caution if visiting the area. These controlled burns will continue until all the debris is removed.
Hydroseeding at Spillway Reconstruction Area Prevents Erosion
Areas of the hillsides near Oroville Dam’s reconstructed main spillway will appear bright green due to the application of a hydroseed mix for site stabilization and erosion control. The hydroseed mix helps to reestablish a root structure in the soil profile to hold it in place. Native species such as yarrow, fescue, California poppy and lupine will help to restore natural ground cover and the green-colored bonded fiber matrix will hold the mix together until the seed can germinate. Hydroseeding is one component of the Oroville Spillways Emergency Recovery Project’s site rehabilitation activities that are scheduled over the next several years.
California Experiences Many Types of Flooding – Are you Prepared?
After a dry summer and fall, wet winter storms add storage to the state’s reservoirs. Yet flooding caused by heavy rains can have devastating results and without proper preparedness, lives, homes, infrastructure and agriculture are at risk of being lost. This winter, be prepared with an emergency evacuation kit, pay attention to weather forecasts and listen to local authorities. Being aware of your risk, because being prepared and taking action can help keep you and your family safe. Visit DWR’s Flood Preparedness Week webpage for more flood safety tips.
DWR Installation of New Lighting on Main Spillway to Occur in 2020
Following manufacturer’s instructions, new lighting installed on Oroville Dam’s main spillway will remain on for a continuous 72-hour period as part of activation testing. It’s anticipated this testing period will now take place after the first of the year. The public’s patience is appreciated as DWR complies with the lights’ activation requirements. After testing is complete, the lights will then be used intermittently based on operational needs.

Current Lake Operations
The elevation of Oroville reservoir nearly 782 feet and storage is about 1.9 million acre-feet. Daily average inflows to the lake have ranged between approximately 4,890 cfs (cubic feet per second) to 11,270 cfs over the past week.
Rain and snow is in the forecast for December 14 and 15 with the chance for additional rain during the week of December 16.
Water is being released from Lake Oroville at a rate of about 3,300 cfs. Water from the reservoir is being used locally for rice decomposition and to support waterfowl habitats and is also being used to meet Feather River flow and environmental requirements in the Sacramento-San Joaquin Delta.
