DWR Announces Initial State Water Project Allocations The Department of Water Resources (DWR) announced on Dec. 1 an initial State Water Project (SWP) allocation forecast of 10 percent of requested supplies for 2024. The SWP provides water to 29 public water agencies that serve 27 million Californians. The initial water supply forecast is the first allocation of the new water year, which began Oct. 1, and is based on current reservoir storage and an assumption of very dry conditions. So far in October and November, storms have not brought as much rain and snow. The allocation has no bearing on current water supplies or water captured in 2023. Most reservoirs in the state remain above average for this time of year following last water year’s wet winter. More information on the initial SWP allocation announcement may be found in DWR’s press release. MAINTENANCE WORK ON MAIN SPILLWAY COMPLETE FOR THE SEASON DWR has completed routine maintenance work on Oroville Dam’s main spillway for the 2023 season. Work this year included routine concrete repair, complete sealant replacement on concrete slabs and wall joints, and a complete inspection of the 51,000 feet of piping that supports the spillway’s improved drainage system. Oroville Dam’s main spillway performed well and operated as designed in 2023, passing over 2,370,000 acre-feet of water – approximately 67 percent of the capacity of Lake Oroville. Due to seasonal temperature variations, spillway releases, and sun exposure, periodic concrete and joint sealant repairs of the main spillway are expected. The spillway was rebuilt to the highest engineering and safety standards with oversight and guidance by the Federal Energy Regulatory Commission (FERC), Division of Safety of Dams (DSOD), and an independent board of consultants. DWR performed a significant amount of inspection and testing throughout construction to verify compliance with project specifications. DWR also provides regular updates to the Oroville Dam Citizens Advisory Commission, a public forum for discussing operations, maintenance, and public safety activities at Oroville Dam and its facilities. OROVILLE PARADE OF LIGHTS Don’t miss Oroville’s annual Parade of Lights event this Saturday, Dec. 9, starting at 6 p.m. in downtown Oroville. This family-friendly event features a beautiful array of decorated floats with dancers, performers, and a marching band continuing the festive entertainment throughout the route. This year’s parade theme is “Christmas Throughout the Year: A Holiday Extravaganza” with floats representing each month of the year. Parade of Lights is organized by the Oroville Chamber of Commerce with event resource support provided by DWR. For more information about the Parade of Lights event, visit visitoroville.com. VEGETATION MANAGEMENT ACTIVITIES DWR and CAL FIRE’s Magalia Fire Center began vegetation cutting, piling, and burning activities this week near the Hyatt Powerplant along Oro Dam Blvd. East. Crews will be onsite Tuesday through Thursday each week, with vegetation management activities continuing for several months. In addition, fuel reduction activities are continuing in the Loafer Creek Recreation Area along Highway 162 (Oro Quincy Highway) for the next couple of weeks. Work schedules are subject to change depending on weather, crew, and equipment availability. Work may cause intermittent trail closures within project areas. Recreational trail users should be cautious when entering work areas and obey all posted trail signage. Smoke from pile burning activities will be visible in the Oroville area. DWR’s Fuel Load Management Plan works to reduce wildfire risk, increase public safety, and enhance forest health around the Lake Oroville area. Ongoing vegetation management of this critical area remains a high priority for DWR and its partners at CAL FIRE, Butte County Fire Department, Butte County Sheriff’s Office, California Conservation Corps (CCC), California Department of Parks and Recreation (State Parks), and the Butte County Fire Safe Council. SALMON SURVEYS DWR scientists are performing weekly surveys in the Feather River through Dec. 22 to record the number of Chinook salmon returning to spawn this season. Approximately two to three boats will be on the river during weekdays conducting surveys. The weekday survey schedule is as follows, but is subject to change due to crew availability and the number of fish encountered:
OROVILLE RECREATION The Lake Oroville Visitor Center will be temporarily closed Friday, Dec. 15 between 7 a.m. and noon for DWR staff training. Visitors may still access nearby trails and outside facilities during the temporary closure.

Free guided tours for school and community groups are available by reservation. Parking and admission to the Visitor Center are free. DWR biologists are using the Feather River Fish Monitoring Station to determine abundance, run timing, and origin (hatchery or natural) of steelhead and Chinook salmon populations. This information will improve the management of these important fish populations. Upstream migrating fish totals between Sept. 11 and Dec. 2 are:
DWR, State Parks, and the Department of Fish and Wildlife maintain over 92 miles of trails in the Oroville area. An interactive map of recreation facilities, including open trails and their permitted uses (hike, bike, horse, multi), is available on DWR’s Lake Oroville Recreation webpage. A paper trail map is available at various locations, including most entrance kiosks and the Lake Oroville Visitor Center. The marinas at Bidwell Canyon and Lime Saddle are open daily and provide a variety of services including a convenience store, gas, and boat rentals. CURRENT LAKE OPERATIONS Lake Oroville is at 812 feet elevation and storage is approximately 2.33 million acre-feet (MAF), which is 66 percent of its total capacity and 131 percent of the historical average. Feather River flows remain at 650 cubic feet per second (cfs) through the City of Oroville with 1,100 cfs being released from the Thermalito Afterbay River Outlet (Outlet) for a total Feather River release of 1,750 cfs downstream. DWR continues to assess releases to the Feather River daily. Visitors to Oroville Dam may also notice minor amounts of water flowing from drains built into the emergency spillway, which is normal and expected with the emergency spillway design. The dam and emergency spillway continue to operate as intended. The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center. The Lake Oroville gage station is identified as “ORO.” All data as of midnight 12/7/2023. Salmon Carcass Surveys Department of Water Resources (DWR) scientists will perform weekly fish carcass surveys in the Feather River through Dec. 22 to record the number of Chinook salmon returning to spawn this season. Approximately two to three boats will be on the river during weekdays conducting carcass surveys. The weekday carcass survey schedule is as follows, but is subject to change due to crew availability and the number of fish carcasses encountered:
STEELHEAD SPAWNING The fish ladder at the Feather River Fish Hatchery reopened Nov. 30 with steelhead spawning operations beginning around mid-December. Steelhead enter the hatchery via the fish ladder that leads up from the Feather River Fish Barrier Dam and can be seen at the viewing windows and facility. Once the spawned fish eggs have hatched, the juvenile fish will be reared at the hatchery for a full year and then released next winter into the Feather River. If there are any surplus fish beyond the production goal, fish may be planted into the Thermalito Afterbay for recreational fishing. Like the juvenile salmon that populate the Feather River, steelhead trout migrate from freshwater to marine (ocean), returning to freshwater environments to spawn. Unlike salmon, they can spawn several times during their lifetime and can live up to eight years. The “steelhead” name comes from their appearance, a more streamlined shape than Chinook salmon with a silvery or brassy color as an adult. The Feather River Fish Hatchery’s spawning operations enable Chinook salmon and steelhead to be released yearly to support Northern California and Pacific Ocean fisheries. DWR owns and maintains the facility and provides funding to the Department of Fish and Wildlife (DFW) for its spawning, rearing, and stocking operations. MAINTENANCE WORK ON MAIN SPILLWAY NEARING COMPLETION DWR is nearing completion of routine maintenance work on Oroville Dam’s main spillway for the season. Surface concrete work on localized areas of the spillway has been extended through Dec. 8 due to favorable weather conditions.

A transcript of the meeting will be available on the webpage in the coming weeks. FEATHER RIVER FISH MONITORING STATION A Feather River Fish Monitoring Station installed by the Department of Water Resources (DWR) in Oroville continues to provide underwater video footage that allows biologists to determine abundance, run timing, and origin (hatchery or natural) of steelhead and Chinook salmon populations. This information helps improve management of these important fish populations in the Feather River and at the Feather River Fish Hatchery. Monitoring stations like this are widely used in many rivers to collect fish population data and provide a safer and faster method of data collection, while still permitting river recreation. Whether traveling downstream or upstream, vessels of all kinds can safely navigate over the structure. DWR’s instructional video illustrates how vessels such as powerboats, drift boats, and kayaks may navigate over the fish monitoring station. Those in more portable water vessels also have the option to use the riverbank and walk around the monitoring station. Upstream migrating fish totals between Sept. 11 and Nov. 11 are:
MAINTENANCE WORK ON MAIN SPILLWAY EXTENDED Routine concrete and joint sealant repair work on localized areas of Oroville Dam’s main spillway has been extended to Dec. 1 due to favorable weather and lower reservoir levels.

VEGETATION MANAGEMENT ACTIVITIES DWR has been awarded Hazard Mitigation Grant Program (HMGP) funds totaling $900,000 from the Federal Emergency Management Agency (FEMA) to complete a 305-acre hazardous fuels reduction project in the Lake Oroville area. Fuel reduction locations include DWR property along Oro Dam Blvd. East, the Bidwell Canyon/Kelly Ridge area, and the Loafer Creek State Recreation Area. This multi-year project will reduce hazardous fuels by thinning vegetation using hand and mechanical methods accompanied by chipping. This project reduces the risk of a catastrophic wildfire by improving defensible space around infrastructure, roads, and residential areas. By proactively reducing ground fuels, thinning overgrown vegetation, and removing dead and dying vegetation, firefighters have a better chance at suppressing wildfires. HMGP work began last week and will continue over the next three years. This work may cause intermittent trail closures within project areas. Recreational trail users should be cautious when entering work areas and obey all posted trail signage. In addition to HMGP activities, DWR and CAL FIRE have resumed vegetation management activities in the Loafer Creek Recreation Area. CAL FIRE hand crews and heavy equipment operators are currently performing prescribed burns throughout Loafer Creek and along HWY 162 (Oro Quincy Highway). Smoke from pile burning activities will be visible in the Oroville area for the next several months. DWR’s Fuel Load Management Plan works to reduce wildfire risk, increase public safety, and enhance forest health around the Lake Oroville area. Ongoing vegetation management of this critical area remains a high priority for DWR and its partners at CAL FIRE, Butte County Fire Department, Butte County Sheriff’s Office, California Conservation Corps (CCC), California Department of Parks and Recreation (State Parks), and the Butte County Fire Safe Council.

The 13-member committee is made up of representatives from state and local government, recreation groups, and business and community organizations. Flood Preparedness Week This week is Flood Preparedness Week, which runs from Oct. 21 to Oct. 28. More than seven million California residents are at risk of flooding, and many don’t realize it. Flooding can occur throughout the state, from rural to urban areas, in valley and desert communities, in mountain regions, and along the coast. Every California county has received a flood-related emergency declaration in the past 20 years. Flooding can also happen at any time of year and can even occur during drought years. Communities that are downslope of recent wildfires are especially prone to flash floods and debris slides, as landscapes impacted by wildfires can take up to five years to recover. In recent years, DWR, as a member of the Feather River Watershed Working Group (FRWWG), helped address wildfire impacts in the watershed surrounding Lake Oroville. Following the North Complex and Dixie Fires, the FRWWG installed erosion control measures to help prevent toxic ash and burned materials from entering the waterways that supply Lake Oroville. This included debris flow measurement, cleanup, and additional water sampling activities. To prepare for flooding, all Californians should follow three basic steps:

This multi-year project will reduce hazardous fuels by thinning vegetation using hand and mechanical methods accompanied by chipping. This project reduces the risk of a catastrophic wildfire by improving defensible space around infrastructure, roads, and residential areas. By proactively reducing ground fuels, thinning overgrown vegetation, and removing dead and dying vegetation, firefighters have a better chance at suppressing wildfires. HMGP work is anticipated to begin Oct. 23 and will continue over the next three years. This work may cause intermittent trail closures within project areas. Recreational trail users should be cautious when entering work areas and obey all posted trail signage. In addition to HMPG activities, DWR and CAL FIRE have resumed vegetation management activities in the Loafer Creek Recreation Area. CAL FIRE hand crews and heavy equipment operators will be working throughout Loafer Creek and along HWY 162 (Oro Quincy Highway) for the next several months. Smoke from pile burning activities will be visible in the Oroville area. DWR’s Fuel Load Management Plan works to reduce wildfire risk, increase public safety, and enhance forest health around the Lake Oroville area. Ongoing vegetation management of this critical area remains a high priority for DWR and its partners at CAL FIRE, Butte County Fire Department, Butte County Sheriff’s Office, California Conservation Corps (CCC), California Department of Parks and Recreation (State Parks), and the Butte County Fire Safe Council. CALIFORNIA PREPARES FOR A POSSIBLE WET EL NIÑO YEAR DWR and its federal and local partners are preparing for the new water year, which started Oct. 1, and the possibility of another wet season under strong El Niño conditions. DWR will utilize the most advanced forecasting tools with our partners at the National Oceanic and Atmospheric Administration (NOAA), the Scripps Institution of Oceanography, and others to prepare for whatever may come to California in the months ahead. DWR and the U.S. Bureau of Reclamation, which operate the State Water Project and Central Valley Project respectively, are closely coordinating to ensure the state’s reservoirs have flood protection space available while storing as much water as possible in case drought conditions return. This past winter’s storms provided a huge boost to the State Water Project (SWP), which captured a total of 3.5 million acre-feet of water in reservoirs since Dec. 1, 2022. Lake Oroville levels recovered and had the single biggest increase in the SWP’s history last water year, gaining more than 2.5 million acre-feet of water between November 2022 and June 2023. More information about El Niño preparations can be found in DWR’s news release. OROVILLE RECREATION DWR biologists are using the Feather River Fish Monitoring Station to determine abundance, run timing, and origin (hatchery or natural) of steelhead and Chinook salmon populations. This information will improve the management of these important fish populations. Upstream migrating fish totals between Sept. 11 and Oct. 13 are:
The Lake Oroville Visitor Center is open seven days a week from 9 a.m. to 5 p.m. Staffed by knowledgeable guides, the Visitor Center features interpretive displays on Oroville Dam, area geology, wildlife and habitat, hydroelectric power, and cultural and historical artifacts. View videos in the theater about the construction of Oroville Dam, walk or hike along nearby trails, and visit the 47-foot-tall observation tower that provides unsurpassed panoramic views of surrounding areas. Free guided tours for school and community groups are available by reservation. Parking and admission to the Visitor Center are free. CURRENT LAKE OPERATIONS Lake Oroville is at 824 feet elevation and storage is approximately 2.48 million acre-feet (MAF), which is 70 percent of its total capacity and 134 percent of the historical average. Feather River releases are at 2,450 cubic feet per second (cfs). Flows through the City of Oroville remain at 650 cfs with releases from the Thermalito Afterbay Outlet (Outlet) at 1,800 cfs for a total of 2,450 cfs downstream of the Outlet. DWR continues to assess releases to the Feather River daily. Visitors to Oroville Dam may also notice minor amounts of water flowing from drains built into the emergency spillway, which is normal and expected with the emergency spillway design. The dam and emergency spillway continue to operate as intended. The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center. The Lake Oroville gage station is identified as “ORO.” All data as of midnight 10/19/2023. Feather River Floating Classrooms Spend time on the beautiful Feather River this fall and join Department of Water Resources (DWR) scientists for educational floats each Saturday through Nov. 11. Rafting trips will float through Feather River spawning habitat while DWR scientists provide information on Chinook salmon conservation efforts, ongoing and planned research, and restoration and monitoring projects. Each Saturday will have three floating classroom sessions with limited seats. Weekend sessions support free floating classroom events for local schools. Reserve your Floating Classroom Tour Tickets on Eventbrite.

Vegetation Management Activities DWR and CAL FIRE have resumed vegetation management activities in the Loafer Creek Recreation Area. CAL FIRE hand crews and heavy equipment operators will be working throughout Loafer Creek and along HWY 162 (Oro Quincy Highway) for the next several months. Starting the week of Oct. 16, CAL FIRE will be performing prescribed burns at Loafer Creek. Work is weather dependent and may require nearby temporary trail closures. Smoke from pile burning activities will be visible in the Oroville area. These activities are removing overgrown ladder fuels, dead and dying vegetation, and minimizing ground fuels to create a more wildfire-resilient landscape. DWR’s Fuel Load Management Plan works to reduce wildfire risk, increase public safety, and enhance forest health around the Lake Oroville area. Ongoing vegetation management of this critical area remains a high priority for DWR and its partners at CAL FIRE, Butte County Fire Department, Butte County Sheriff’s Office, California Conservation Corps (CCC), California Department of Parks and Recreation (State Parks), and the Butte County Fire Safe Council. Vegetation management activities are ramping up for the season and will continue through Spring 2024 as weather conditions permit and crews are available. MAINTENANCE WORK ON MAIN SPILLWAY UNDERWAY Routine concrete and sealant repair work on localized areas of Oroville Dam’s main spillway continues this month. While the main spillway continues to perform well and operate as designed, periodic concrete and sealant repairs of the spillway are expected due to seasonal temperature variations, spillway releases, and sun exposure. In 2023, Oroville Dam’s main spillway passed over 2,370,000 acre-feet of water – approximately 67 percent of the capacity of Lake Oroville. Construction work is expected to continue through Nov. 15 but is dependent on weather and Oroville Dam operations. DWR will monitor reservoir levels and weather forecasts closely and will complete repair work early if spillway releases are required for flood control. Approximately 500 square-feet of total concrete repairs are anticipated, representing less than 0.1 percent of the spillway’s surface. Work so far has included inspection of approximately 40 percent of the 51,000 feet of piping that supports the spillway’s improved drainage system. The contractor also began concrete maintenance and joint sealant work on select chute slab and wall joints this week. The spillway was rebuilt to the highest engineering and safety standards with oversight and guidance by the Federal Energy Regulatory Commission (FERC), Division of Safety of Dams (DSOD), and an independent board of consultants. DWR performed a significant amount of inspection and testing throughout construction to verify compliance with project specifications. DWR also provides regular updates to the Oroville Dam Citizens Advisory Commission, a public forum for discussing operations, maintenance, and public safety activities at Oroville Dam and its facilities. OROVILLE RECREATION DWR biologists are using the Feather River Fish Monitoring Station to determine abundance, run timing, and origin (hatchery or natural) of steelhead and Chinook salmon populations.

CALIFORNIA WATER PLAN 2023 From severe, multi-year droughts to sudden flooding, California is experiencing the intensifying impacts of climate change. To better prepare and plan for a future with climate extremes, DWR has released the Public Review Draft of California Water Plan Update 2023. For decades, the California Water Plan has served and evolved as a strategic blueprint for managing and developing the state's water resources. This comprehensive plan is meant to guide water managers, including water districts, cities, counties, and Tribal communities. Every five years the California Water Plan is updated, as mandated by the State Water Code, to reflect current water conditions and State government priorities. These updates are shaped by various factors, including the Water Resilience Portfolio, input from interested parties, state needs, and the Governor's commitment to climate action, as demonstrated in California's Water Supply Strategy: Adapting to a Hotter, Drier Future. Public comments on the Draft California Water Plan Update 2023 are being accepted through Oct. 19, 2023. Comments may be submitted through an online form or to CWPCOM@water.ca.gov.

OROVILLE SALMON FESTIVAL DWR had a great time supporting the City of Oroville’s Salmon Festival celebrating the migration of native Chinook salmon in the Feather River. Thank you to everyone who stopped by our educational booth and took a free tour of the Feather River Fish Hatchery. DWR staff estimated that approximately 600 children and adults participated in DWR-led tours of the Hatchery, where Chinook salmon and steelhead are raised to improve fisheries populations throughout the state. DWR also partnered with the Oroville State Theater to showcase videos about efforts to support vital salmon habitat restoration, fisheries health, and population growth. Many also saw salmon up close as they paddled down the river with rafting tours featuring DWR biologists who shared information about the salmonid life cycle and Feather River. Tickets for this unique experience are still available. Reserve your Floating Classroom Tour Tickets on Eventbrite.
