February 13, 2017 at 7:40 AM 3:00 am update from the Nevada County Fairgrounds. The Fairgrounds is available for evacuees and animals. We are not full, and we have room in our buildings and our RV Park.

We have about 600 people on the grounds, about 15 large dogs, and many small animals. The Red Cross has notified us that the Salvation Army will be bringing breakfast and lunch to all the evacuees in the morning; however, they are in need of prepackaged snack food (no homemade food is allowed) and blankets for the evacuees. There is plenty of bottled water, so no need for water donations. They are also in need of dog and cat food for the small animals.

The Nevada County Veterinary Disaster Response Team (who is overseeing the large animal evacuations) has about 15 large dogs, and they have enough food and supplies for these animals, so there is not a need for food and blankets for them at this time. All prepackaged snack food, blanket, and small animal pet food donations can be dropped off at Gate 1 at the Fairgrounds, and Red Cross will oversee the distribution. Thank you for your generosity, and your patience as we work with the various organizations to best help those in need.

February 12, 2017 at 6:25 PM Based on information received from the California Department of Water Resources (DWR) and the incident command team managing Lake Oroville, counties and cities near Lake Oroville and the surrounding area issued evacuation orders for residents.

The concern is that erosion at the head of the auxiliary spillway threatens to undermine the concrete weir and allow large, uncontrolled releases of water from Lake Oroville.  Those potential flows could exceed the capacity of downstream channels. To avert more erosion at the top of the auxiliary spillway, DWR doubled the flow down its main spillway from 55,000 cubic feet per second (cfs) to 100,000 cfs.

The next several hours will be crucial in determining whether the concrete structure at the head of the auxiliary spillway remains intact and prevents larger, uncontrolled flows. Current flows are contained with downstream channels.

Flow over the auxiliary spillway weir began Saturday morning and has slowed considerably.

DWR officials expect that flow to stop entirely soon, which will reduce the erosion on the downstream side of the structure. Oroville Dam itself is sound and is a separate structure from the auxiliary spillway.

February 12, 2017 at 6:22 PM Butte County Sheriff: The Lake Oroville Dam Auxiliary Spillway structure has suffered potentially catastrophic damage as a result of erosion secondary to water flow. This damage could result in catastrophic failure of the Auxiliary Spillway. The California Department of Water Resources has increased exhaust water flow from the Gated Spillway to 100,000 cfs in an attempt to decrease Lake Oroville water levels. This effort is an attempt to reduce flow from the Auxiliary Spillway. As an additional measure, helicopters will be depositing rock filled containers to strengthen the potential failure point. This development caused the Butte County Sheriff, Kory L. Honea, to order the mandatory evacuation of the City of Oroville, south to the Butte County Line. Residents are advised to evacuate north to the City of Chico. An evacuation shelter has been established at the Silver Dollar Fairgrounds. The Sheriff, in an effort to safe guard residents of Butte County, had no choice but to make the decision to require this mandatory order.
