Oroville Field Division Work Continues Oroville Field Division (OFD) staff continue to carry out essential duties including operations of Oroville Dam and affiliated power plants, facility maintenance, and monitoring activities. Following guidance from Governor Gavin Newsom and the California Department of Public Health, OFD has made several changes in response to the dynamic public health emergency including social distancing, telework, and increased sanitary precautions for staff. Please remember that California's water treatment process removes and kills viruses, including COVID-19. Additionally, tap water is cheaper, easily accessible, and doesn't contribute to plastics pollution. Oroville and Upper Feather River Lakes Closures Update As a result of the COVID-19 pandemic, most of the recreation facilities associated with the Lake Oroville State Recreation Area have been closed, as well as the Lake Oroville Visitors Center and public access to the Feather River Fish Hatchery. The U.S. Forest Service closed all developed recreation sites indefinitely including boat launch facilities and campgrounds at the State Water Project facilities of Frenchman Lake, Lake Davis, and Antelope Lake in Plumas County. For information on Forest Service facilities, find your national forest at https://www.fs.usda.gov/. Information regarding the status of California Department of Parks and Recreation facilities can be found at “Flatten the Curve at State Parks”. Information regarding the Oroville Wildlife Area, including the Thermalito Afterbay, can be found at https://wildlife.ca.gov/Lands/Places-to-Visit/Oroville-WA or by calling (916) 358-2900. DWR Continues Brush Clearing Work DWR continues to implement the Fuel Load Management Plan (FLMP), which aims to reduce wildfire risk, improve public safety, and enhance forest health around Lake Oroville. Crews continues to remove hazardous fuels, including overstocked trees and underbrush, from approximately 9.5 acres at project sites near the Nelson Bar Car-top Boat Launch and along Oroville Dam Boulevard East near the Hyatt Powerplant. Current Lake Operations The elevation of Oroville’s reservoir is about 822 feet and storage is about 2.46 million acre-feet. Daily average inflows to the lake have ranged between 4,869 cfs (cubic feet per second) to 5,400 cfs over the past week. Dry and warming conditions are forecasted through the weekend and into the week of April 27. Currently in the Northern Sierra Basin rainfall is below average, at 58 percent of normal, and snowpack is also below average, measuring 48 percent of normal for this time of year. Flows through the City of Oroville are about 650 cfs and about 900 cfs below the Thermalito River Outlet. Total releases to the Feather River are at 1,550 cfs.

Fire Suppression System Work to Impact Oroville Dam Waterline A project to install fire suppression systems at the Oroville Project Headquarters office trailers at Oroville Dam’s Upper Overlook is anticipated to require a temporary shut-off of the waterline across Oroville Dam for an approximately 12-hour period during the week of April 20. Restrooms at the entrance to Oroville Dam will be closed during this time. The shut-off will also temporarily decrease the water pressure inflating the rubber seals around the spillway gates allowing additional seepage to be visible on the main spillway. Installation of Piezometers at Oroville Dam Completed DWR contractors have completed installation of eight new piezometers at the base of the dam. These moisture-sensing devices will further DWR’s efforts to monitor seepage and will be used to confirm the seepage measurements DWR already collects. Seepage is normal and expected, especially in large, earthen dams like Oroville. Seepage is measured and collected through a drainage system. If seepage were to change dramatically, it would indicate an issue that would need further investigation. This work is part of the early implementation of the Oroville Dam Safety Comprehensive Needs Assessment (CNA), which is focused on identifying priorities and appropriate solutions to bolster the integrity and resiliency of the Oroville Dam complex to ensure public safety. There were 56 piezometers initially installed in the dam fifty years ago which, as anticipated, have since stopped functioning. DWR plans to install additional piezometers throughout the facility in the coming years.

Feather River Fiesta Days Community Event Postponed The Oroville Feather Fiesta Days Planning Committee has postponed the May 9, 2020 Feather River Fiesta Days event due to the ongoing public health emergency. The Committee is considering holding the event this summer if community gatherings are permitted at that time. Information can be found on the Feather Fiesta Days Facebook page @FeatherFiestaDays. DWR Continues Brush Clearing Work DWR continues to implement the Fuel Load Management Plan (FLMP) which aims to reduce wildfire risk, improve public safety, and enhance forest health around Lake Oroville. Crews continues to remove hazardous fuels, including overstocked trees and underbrush, from approximately 9.5 acres at project sites near the Nelson Bar Car-top Boat Launch and along Oroville Dam Boulevard East near the Hyatt Powerplant. Current Lake Operations The elevation of Oroville’s reservoir is about 819 feet and storage is about 2.41 million acre-feet. Daily average inflows to the lake have ranged between 5,374 cfs (cubic feet per second) to 6,471 cfs over the past week. There is a slight chance of rain early in the week of April 20. Currently, in the Northern Sierra Basin, rainfall is below average, at 59 percent of normal, and snowpack is also below average, measuring 61percent of normal for this time of year. On Friday April 17, flows through the City of Oroville will start ramping down from 1300 cubic feet per second (cfs) and will gradually reach 650 cfs by Wednesday, April 22. This is the culmination of a 2-week temporary “flow pulse” that DWR provided for the benefit of juvenile salmon and steelhead in the Feather River. Releases from the Thermalito Afterbay were adjusted during this time period so that the total flow to the Feather River below the Thermalito Afterbay remained constant at 1,550 cfs. This total release of 1,550 cfs to the Feather River below the Thermalito Afterbay will continue. All data as of midnight 4/16/20 ### Know someone who would like to receive Community Updates?

CAL FIRE – Butte County/DWR Loafer Creek Work Nearly Completed CAL FIRE and DWR work to reduce wildfire risk, improve public safety, and enhance forest health around Lake Oroville through the CAL FIRE Vegetation Management Program and DWR’s Fuel Load Management Plan (FLMP). CAL FIRE/DWR work at Loafer Creek is scheduled to conclude the week of April 13. DWR contractors have removed hazardous fuels, including overstocked trees and underbrush, from approximately 20 acres at the south end of Loafer Creek where CAL FIRE crews will soon complete their burning of the brush piles. Smoke from the burn piles may be visible by area residents and motorists on State Route 162 near the Forbestown Road area. Current Lake Operations The elevation of Oroville’s reservoir is about 814 feet and storage is about 2.35 million acre-feet.
