Lake Oroville Community Update
July 12, 2019
Lake Level
Water releases from Hyatt Powerplant are approximately 7,495 cubic feet per second (cfs). The current elevation of Oroville reservoir is 888 feet. As we continue through summer, DWR will increase releases to the river from Lake Oroville to supplement the natural flows of the Feather River to meet environmental needs, salinity standards, and south of Delta State Water Project exports. Coordinated releases from the federal Central Valley Project and the State Water Project from Lake Oroville help balance conditions throughout the Sacramento Valley watershed. Current weather forecasts and expected inflow will not require the use of Oroville’s main spillway. If DWR determines that it is necessary to use the main spillway, in addition to Hyatt Powerplant, DWR will notify the public and media.
Road Closures Near Oroville Dam Begin July 15
Contractors will begin road work on Glen Drive on July 15 and Oroville Dam Blvd. East July 19 to improve the roadway surface impacted by installation of a new fiber optic conduit running from the Operations and Maintenance Center at the Oroville Field Division to the Hyatt Powerplant Complex. Paving and road maintenance is expected to last two weeks and will result in periodic road closures and traffic delays.
Check out the map below or the news release for more details, at https://water.ca.gov/News/News-Releases/2019/July-19/Road-Closures-Near-Oroville-Dam-Begin-July-15

Feather Fish Hatchery Maintenance Closure
As a reminder, the Feather River Fish Hatchery in Oroville was closed this week and will remain closed to the public for approximately four weeks for routine maintenance and inspections.
Every five years, DWR and the California Department of Fish and Wildlife (CDFW) perform inspections and maintenance of the hatchery. This work requires shutting off the water supply to the hatchery and moving all fish out of the hatchery. Accordingly, the Chinook salmon raised in the hatchery for Lake Oroville were planted in the Lake and the steelhead were transported to the Thermalito Annex hatchery facility. Once maintenance work is complete, the steelhead will be transported back to the Feather River Fish Hatchery where they will remain until February of 2020 and then released to the Feather River. During the closure, the fish ladder will be closed preventing any adult Chinook salmon from entering the facility.
Check out the news release for more details, at https://water.ca.gov/News/News-Releases/2019/July-19/Feather-River-Fish-Hatchery-to-Close-for-Maintenance.
Spillway Boat Ramp Reopening
Later this summer, DWR will reopen public access to the Spillway Boat Ramp. The boat launch and parking lots will be open to the public Friday through Sunday from 5 AM to 11 PM beginning Friday, August 2, 2019. The Spillway Boat Ramp will remain closed Monday through Thursday to accommodate ongoing construction. DWR plans to open the boat ramp seven days a week this fall once major construction activities are completed, although access may be restricted again once construction ramps back up in early 2020. New security measures are currently being updated in coordination with local and state law enforcement agencies including the California Highway Patrol, Butte County Sheriff’s Office, California State Parks and Cal OES.

Oroville Operations Update
​Lake Levels
Water releases from Hyatt Powerplant are approximately 4,009 cubic feet per second (cfs). The current elevation of Oroville reservoir is 895 feet. The Feather River watershed snowpack has mostly melted and use of the main spillway to manage lake levels is unlikely. However, if DWR determines that it is necessary to use the main spillway, in addition to Hyatt Powerplant, DWR will notify the public and media. 
A full reservoir is a welcome sight after years of drought and low lake levels to accommodate reconstruction. A filled lake provides optimal recreation opportunities and serves as a vital water bank account to help California cope with future drought conditions. It is common for the reservoir to stay relatively full during the summer months in an above average water year. In 2010 – 2011, another very wet year, the reservoir sat an elevation between 898 and 899 feet for the entire month of July.
DWR Reopening Public Access to Top of Oroville Dam
DWR plans to reopen public access to the top of the dam (Dam Crest Road) next Saturday, June 29 for pedestrians, bicyclists and persons with disabilities. The public will have access to the pedestrian lane on the lakeside of Dam Crest Road from 5 a.m. to 11 p.m., as well as parking at the Upper Overlook. For safety considerations, the public will not be able to drive across the top of the dam.
As part of the reopening, DWR staff will be up on the Dam Crest Road in the morning of the 29thto provide informational materials, answer questions and meet with the public.
DWR, California Highway Patrol and California State Parks are operating Dam Crest Road with new security measures to further ensure public safety at the facilities. Construction activity is ongoing in the area and construction vehicles will be using a portion of Dam Crest Road. Expect slower traffic and please obey all road and traffic signs. DWR has also contracted with the Butte County Sheriff’s Office for increased patrols of the Oroville facilities to ensure public safety. 
Spillway Boat Launch Ramp Reopening
Access to the Spillway Boat Launch ramp is anticipated to partially reopen in early August. More details to follow.
4th of July Celebration in Oroville
Oroville is always a great place to celebrate Fourth of July.  Several local partners including DWR, the Rotary Club of Oroville and California State Parks are hosting a firework show at the Thermalito North Forebay recreation area, as well as at the nearby Feather River Recreation and Park District's Nelson Sports Complex on July 4.

Follow the event’s Facebook page at Lake Oroville Fireworks for the latest information.
Update on Lake Oroville Algae Bloom
Algae is a natural component of water ecosystems yet certain conditions, including hot weather, can cause algae to grow rapidly causing “blooms” that may harbor harmful toxins.  DWR environmental scientists regularly test for toxins throughout the summer. The “Caution Advisory” for a ‘bloom’ in the Thermalito Afterbay has been lifted as microcystin levels have decreased. A "Caution Advisory" remains in effect for algae found in the upper reaches of Lake Oroville’s Middle Fork. Visitors to area waterways are advised to avoid algae or scum in the water which can be hazardous to pets and people, especially children. Watch for advisory notices which will be posted at all boat launch facilities and water recreation sites. For more information, visit California Water Boards website at https://mywaterquality.ca.gov/habs/index.html.

​Oroville Operations UpdateMain Spillway
Due to late precipitation and based on inflows, DWR has taken steps to prepare for potential use of the main spillway.
Currently, lake levels are being managed with releases from Hyatt Powerplant.
If DWR determines that it is necessary to utilize the main spillway in addition to Hyatt Powerplant to manage lake levels, DWR will notify the public and media. In early April, DWR utilized the reconstructed main spillway to make additional releases from the Oroville reservoir and the spillway operated as designed.
Lake Levels
Water releases from Hyatt Powerplant are approximately 5,000 cubic feet per second (cfs). The current elevation of Oroville reservoir is 894 feet.
A full reservoir is a welcome sight after years of drought and low lake levels to accommodate reconstruction. A filled lake provides optimal recreation opportunities and serves as a vital water bank account to help California cope with future drought conditions. It is common for the reservoir to stay relatively full during the summer months in an above average water year. In 2010 – 2011, another very wet year, the reservoir sat an elevation between 898 and 899 feet for the entire month of July.
Ongoing Work on Dam Crest Road
DWR is aiming to reopen public access to the top of dam (Dam Crest Road) this summer. In anticipation of the public opening DWR crews began removing small panels from the dam crest roadside barriers that contain asbestos on Tuesday, June 11. This work is expected to last for two weeks. Crews will wear protective suits and respirators to clean the panels in accordance with state health and safety regulations. DWR will share reporting about this work with Butte County Air Quality Management District and California Air Resources Board.
4th of July Celebration in Oroville
Oroville is always a great place to celebrate Fourth of July.  The event is sponsored by the Rotary Club of Oroville and will be held at California State Park’s Thermalito North Forebay recreation area, as well as at the nearby Feather River Recreation and Park District's Nelson Sports Complex. Activities will start at the Sports Complex 4 p.m. to 8 p.m. and the fireworks display will start 30 minutes after sunset.
DWR has partnered with CALFIRE/Butte County and State Parks to prepare for the event including conducting a Vegetation Management Project to remove dry grass from an area in the North Forebay. The controlled burn conducted on June 10 around the location of the fireworks launch area will prevent the possibility of the fireworks starting a wildfire.
Follow the event’s Facebook page at Lake Oroville Fireworks for the latest information.

May 2, 2019Oroville Operations and Main Spillway UpdateLake Level
The current Oroville reservoir elevation is 884 feet. Total releases into the Feather River continue at 10,500 cubic feet per second (cfs). DWR is safely managing Oroville reservoir inflows from melting snowpack and plans to keep lake levels high through spring and summer. DWR is operating the reservoir in accordance with normal state and federal regulations. A full lake is a welcome sight after years of drought and low levels to accommodate reconstruction. Good news as we head into the summer months for all those who love to recreate on the lake!
Thermalito Diversion Pool and Brad Freeman Trail Reopening
The Thermalito Diversion Pool and Brad Freeman Trail will reopen to the public on Friday, May 3. Kayakers, mountain bikers and hikers can access both areas seven days a week from 8 a.m. to sunset. Kayaks, non-motorized boats (electric motors allowed) and non-trailered boats can access the day use area located along Burma Road and bikers and hikers can take advantage of the two-mile section of the Brad Freeman Trail along the northern shore of the Diversion Pool.
Main Spillway
Releases from the Hyatt Powerplant are adequate to meet operational requirements of the reservoir and there is no need to use the main spillway at this time. However, DWR may need to use the main spillway again this spring to manage inflows from snowmelt and will notify the public and media if this is necessary.
The Oroville main spillway is fully reconstructed and performed as designed when it was used in early April. DWR and expert consultants continue to monitor the main spillway, so workers may be visible on the spillway structure. When it is not in use, water on the spillway is from normal seepage through the spillway gates, which were not designed to be watertight.
Road Construction
Repaving operations continue on Oroville Dam Crest Road, the Spillway Boat Launch facility, and other nearby roads. Paving construction vehicles will continue to use Hyatt Access Road through May 29. Motorists and residents should anticipate additional construction traffic on Canyon Drive and on Oro Dam Blvd. East to the Hyatt Access Road Monday through Saturday from 6 a.m. to 6 p.m. DWR apologizes for any inconvenience and will notify the public when there are any changes to this information. Thank you for your continued patience.
