Water Quality Monitoring Underway The Department of Water Resources (DWR) recently installed water quality monitoring devices called sondes in Lake Oroville and the Thermalito Diversion Pool. Sondes measure the water’s temperature, pH (acidic or basic level of hydrogen), dissolved oxygen (oxygen levels available to aquatic organisms), and turbidity (the clarity of water). Sonde data is collected around the clock every 15 minutes and is analyzed by the Water Quality Section of DWR’s Northern Region office. The monitoring devices are expected to remain in place until the runoff season ends, which is typically around May or June. Routine water quality monitoring occurs on a monthly basis in Lake Oroville including three locations in the forks of the Feather River added to monitor runoff from burn scar areas in the Feather River watershed. In 2020, the multi-agency “Watershed Working Group”, led by the California Governor’s Office of Emergency Services (CalOES), implemented targeted monitoring of rivers, lakes, and other surface waters in the North Complex and Dixie fire burn areas and downstream. The Central Valley Regional Water Quality Control Board (Water Board), the California Department of Fish and Wildlife (CDFW), and DWR collect and test water samples for analysis. STATE WATER PROJECT CAPABILITY REPORT The DWR released the State Water Project Delivery Capability Report 2021, which is generated every two years for the State Water Project’s (SWP) 29 water agencies for water supply planning. With California entering a possible fourth dry year, the report will help water managers better understand how key factors like climate change and regulatory and operational considerations affect the operation of the SWP under historical and future scenarios. The report includes estimates on the SWP’s water delivery capability for current and future conditions based on three major factors:
DWR OFFERS GRANT PROGRAMS DWR is accepting applications for $510 million in financial assistance to support water supply reliability, yard transformation, and migratory birds as California continues to be impacted by climate change and several years of drought conditions. “California is moving aggressively to transform the way we use and manage water so we can thrive in a hotter, drier future,” said DWR Director Karla Nemeth. “Thanks to the leadership of Governor Newsom and the State Legislature, we are deploying much-needed funding to support communities, farmers, and wildlife as we stretch existing supplies and build climate resilience.” The different grant programs target communities that rely on groundwater, farmers willing to support water conservation in the Delta and aid migratory birds, and an Urban Community Drought Relief Grant Program to help large organizations, water agencies, and communities build resilience, replace thirsty lawns with California native landscaping, and promote water conservation. Information on who is eligible and how to apply before respective deadlines is available on DWR’s News Releases webpage.

Over the past several months, DWR has been sharing on its social media channels newly created videos and a storymap featuring some of these projects. The content highlights the ways DWR and its partners are restoring critical habitat, improving migration success, and increasing monitoring efforts to better track the status of salmon populations and devise new strategies to improve their status, especially as climate change impacts increase. These videos and other educational videos about salmon can be found on DWR’s social media channels – Twitter, Facebook, and Instagram – as well as on the DWR YouTube channel (search for Salmon 2022). The storymap, first found in the news release “State Agencies Partner to Support Salmon Populations While Supplying Water To Millions of Californians” published this spring, has been updated with each new video. A selection of these videos, as well as a virtual tour of the Feather River Fish Hatchery, will be shown at Oroville’s historic State Theater during the Salmon Festival on Saturday, Sept. 24. SALMON FESTIVAL The Oroville Salmon Festival is always held on the last Saturday in September to celebrate the annual return of Chinook salmon to the Feather River. The 10 a.m. to 4 p.m. event on Sept. 24 is centered around the Feather River Fish Hatchery and Historic Downtown Oroville. From an ‘Arts & Crafts Alley’ and Oro Dam Cruisers ‘Gold Rush Car Show’ on Montgomery Street, to a kids activity zone, food vendors (including BBQ salmon), music, live glass blowing, and informational booths, visitors and families will find many activities to enjoy in Oroville’s historic downtown and along the Feather River levee. North of downtown Oroville, across the Feather River, the Feather River Fish Hatchery will open at 9 a.m. and close at 3 p.m. for visitors wishing to learn more about the yearly return of Chinook salmon to the river. Educational tours will be offered throughout the day and visitors will find informational booths, food, a mobile fish exhibit, and a chance to cast a fly-fishing rod. On the northeast side of the hatchery site, the Fish Barrier Dam Overlook, fish ladder, and underwater viewing window are also open to the public. Those wanting to see the salmon in their natural habitat can sign up for the Forebay Aquatic Center’s “Feather River Salmon Tours” kayak trips down the Feather River. DWR biologists will offer participants education about the salmonid life cycle and river habitat. For details, visit the Salmon Festival’s website. HATCHERY FISH LADDER IS OPEN Chinook salmon are completing their life cycle and returning home to the Feather River to lay eggs for the next generation of salmon. The Feather River Fish Hatchery opened the fish ladder on Sept. 19. Visitors to the Hatchery’s Fish Barrier Dam Overlook Viewing Area can view salmon congregating and jumping in the Feather River and see them up close through the Underwater Viewing Window as they swim up the fish ladder. The Overlook is located off Table Mountain Boulevard north of the Hatchery. Visitors are also encouraged to visit the Hatchery, open daily 8 a.m. to 3 p.m. The Feather River Fish Hatchery’s spawning operations enables millions of Chinook salmon to be released every spring. This year, the hatchery released 11.3 million young Chinook salmon smolts and 497,000 steelhead to the waters of the Feather River, San Pablo Bay, and San Francisco Bay to support Northern California and Pacific Ocean fisheries. The Feather River Fish Hatchery is a California State Water Project facility owned and maintained by the California Department of Water Resources (DWR), which funds hatchery operations. The California Department of Fish and Wildlife (CDFW) operates the hatchery, including fish spawning, rearing, and stocking activities. OROVILLE RECREATION The Spillway boat ramp and the Lime Saddle boat ramp are closed due to lake elevations falling below safe launching levels. The Loafer Point Stage II and Bidwell Canyon Stage III ramps continue to be open and are anticipated to remain open through the winter. Boaters are reminded the Lime Saddle Marina will remain open and shuttle service to moored boats is available from 8:30 am. to 4 p.m. The Bidwell Canyon Marina will also be open from 8:30 am. to 8 p.m. with shuttle service available during that time. A return to warmer temperatures and less smoke from area wildfires provides a welcome opportunity to take advantage of the spectacular views from the crest of Oroville Dam. Visitors can often see bicyclists, walkers, and joggers on the 1.01-mile length of the crest (2.02 miles round-trip) where a near constant breeze makes for a comfortable exercise experience and offers occasional spotting of Lake Oroville’s bald eagles riding the air currents by the dam.. The Lake Oroville area has over 92 miles of trails, all open to hiking, with some also allowing for horseback riding, some also allowing biking, and some designated for “multi-use” where all three activities may occur on the same trail. The trails provide users with spectacular views of Lake Oroville and the valley, home to the Sutter Buttes – named the smallest mountain range in the world. Trails and their permitted uses, day use areas, boat ramps and other recreation facilities are featured on DWR’s interactive map on DWR’s Lake Oroville Recreation webpage.

BLUE GREEN ALGAE MONITORING While monitoring by DWR environmental scientists for blue-green algae and their toxins at Lake Oroville, the Thermalito North Forebay, and the Thermalito Afterbay only goes through Labor Day, DWR staff will respond to test any observed algal blooms. There are currently no harmful algal bloom (HAB) advisories for any of those waterbodies. If elevated levels of cyanobacteria toxins are found, DWR staff work with California’s Regional Water Quality Control Board and recreation area managers to notify the public and post advisory signs at affected waterbodies. To learn more about HABs, or to report a HAB, visit the Water Board’s website. Blue-green algae (cyanobacteria) is a natural component of ecosystems. Under certain conditions, including warmer temperatures and increased nutrient loads, algae can grow rapidly causing “blooms.” Algal blooms sometimes produce toxins that can be harmful to people and animals. CURRENT LAKE OPERATIONS The elevation of Oroville’s reservoir is about 704 feet elevation and storage is about 1.28 million acre-feet (MAF), which is 36 percent of its total capacity and 64 percent of historical average. Expect a reprieve from the extreme warm temperatures this weekend through next week, with temperatures in the low-90s over the weekend and further dropping to the high-to-mid-80s next week. The Feather River releases are currently at 3,500 cubic feet per second (cfs) and continue to meet downstream Delta water quality and outflow needs. Flows through the City of Oroville are 800 cfs with 2,700 cfs released from the Thermalito Afterbay Outlet (Outlet) for a total of 3,500 cfs downstream of the Outlet. On Sunday, Sept. 11, flow from the Outlet will be reduced from 2,700 cfs to 2,200 cfs for a total downstream flow of 3,000 cfs. The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center at www.cdec.water.ca.gov. The Lake Oroville gage station is identified as “ORO”. All data as of midnight 9/8/2022 California is in its third year of drought conditions. With water conservation now a way of life in California, everyone is encouraged to find ways to save water. See tips, tools, and ideas on the Save Our Water website. Information about real time local hydrological conditions, forecasts, and water conditions is available on DWR’s new website California Water Watch August 26, 2022 Grebes Nests Receive Help from DWR Western and Clark’s grebes, with their distinctive red eyes, graceful necks, and long yellow bills, have returned to the Thermalito Afterbay for their nesting season. The shallow nature of the Afterbay is perfect for these two species of grebes who, along with only a few other aquatic bird species, build their nests on the water’s surface. Reservoirs like Thermalito Afterbay support more than 90 percent of the state’s breeding-grebe population, according to the Audubon Society. DWR voluntarily restricts fluctuating the elevation of the Thermalito Afterbay for several weeks during the grebes nesting season because significant decreases in reservoir elevation could strand the nests out of the water or submerge them if elevations increase. Find more information about the grebes on the DWR Updates webpage. Photos can be found on DWR’s Pixel webpage – enter Grebes in the search bar after creating a free username and password to log in. Fish Advisory for Antelope Lake The California Office of Environmental Health Hazard Assessment (OEHHA) released an advisory for safe eating advice for black bass species, bullhead species, Golden Shiner, and sunfish species caught at Antelope Lake in Plumas County due to levels of mercury found in fish caught from the lake. The fish species tested at Antelope Lake had lower contaminant levels than is typical at many other California water bodies. All species tested at Antelope Lake can be eaten at least two times a week. Mercury is released into the environment from mining and burning coal. It accumulates in fish in the form of methylmercury, which can damage the brain and nervous system, especially in developing children and fetuses. Because of this, OEHHA provides recommendations for safe eating that vary by age and gender. More information can be found in the OEHHA news release. OROVILLE RECREATION AND BOAT RAMP UPDATE The boat ramp at Lime Saddle recreation area will be closing Monday, Aug. 29 as lake elevations fall below safe launching levels. The Lime Saddle Marina will remain open. The Bidwell Canyon, Spillway, and Loafer Point boat ramps remain open, along with the Lime Saddle and Bidwell Canyon marinas. Reservations for campgrounds in the Lake Oroville State Recreation Area (LOSRA) can be made by visiting the California Department of Parks and Recreation (CA Parks) LOSRA website. The Lake Oroville area has over 92 miles of trails, open to hiking, with some also allowing for horseback riding, some also allowing biking, and some designated for “multi-use” where all three activities may occur on the same trail. The trails provide users with spectacular views of Lake Oroville and the valley, home to the Sutter Buttes – named the smallest mountain range in the world. Trails and their permitted uses, day use areas, boat ramps and other recreation facilities are featured on DWR’s interactive map on DWR’s Lake Oroville Recreation webpage. Step inside the Lake Oroville Visitor Center, open Tuesday through Thursday from 9 a.m. to 5 p.m., to learn about the State Water Project and history of the area. The Thermalito Forebay and Afterbay also provide a wide range of recreation opportunities including fishing, hiking, biking and boating. Non-motorized boating is permitted in the North Forebay, and motorized boating is permitted in the South Forebay and Afterbay. The North Forebay Aquatic Center has kayaks, paddle boards, and other watercraft available for rent. Non-motorized boating is also permitted in the Thermalito Diversion Pool with car-top boat launching access just before the restroom on Cherokee Road. Lake Oroville and the Oroville Wildlife Area also have car-top boat launch areas. TRACKING DOVE POPULATIONS Staff from the California Department of Fish and Wildlife (CDFW), along with assistance from DWR staff, have been in the Oroville Wildlife Area (OWA) since July 11 to collect information on the local mourning dove population. Working in the safflower and sunflower fields in the OWA, planted by CDFW staff to provide a readily available food source for doves and many other bird species, staff successfully captured and placed identifying bands on 33 doves. Mourning doves are an important migratory game bird and California is one of 39 states participating in a national effort to monitor the mourning dove population in order to better estimate annual survival and guide harvest-management decisions. CDFW and DWR staff record the sex and approximate age of each banded bird and place a metal band with a unique identification number and a toll-free phone number to report the band around the dove’s leg. The hunter is the critical link in the dove banding study. Their reporting of the dove’s leg band enables wildlife managers to understand the effects of annual hunting regulations on mourning dove populations and allows for greater understanding of their migratory patterns. The Oroville Wildlife Area is a popular hunting location and CDFW expects 80 to 100 opening day hunters when Dove season opens on Sept. 1. For more information on CDFW activities in the OWA to increase forage for local and migratory birds, visit the DWR Updates webpage and search 'sunflower' to access the digital article and previous stories in the Lake Oroville Community Update newsletter. CHINOOK SALMON RETURN TO THE FEATHER RIVER Chinook salmon are completing their life cycle and returning home to the Feather River to lay eggs for the next generation of salmon. The Feather River Fish Hatchery plans to open the fish ladder the week of Sept. 12 to begin hatchery spawning operations which enables millions of Chinook salmon to be released to the river every spring. Visitors to the Hatchery’s Fish Barrier Dam Overlook Viewing Area can watch salmon jumping and after the fish ladder opens in mid-September, visitors can watch salmon swim up the ladder at the Underwater Viewing window. The Overlook is located off Table Mountain Boulevard north of the Hatchery. Visitors are also encouraged to visit the hatchery (open daily 8 a.m. to 3 p.m.) and attend the 28th Annual Salmon Festival in Oroville on Sept. 24. BLUE GREEN ALGAE MONITORING DWR environmental scientists regularly monitor Lake Oroville, the Thermalito North Forebay, and the Thermalito Afterbay for blue-green algae and their toxins, taking water samples from various locations regularly from Memorial Day through Labor Day. There are currently no harmful algal bloom (HAB) advisories for Lake Oroville, the Thermalito Forebay, or the Thermalito Afterbay. If elevated levels of cyanobacteria toxins are found, DWR staff work with California’s Regional Water Quality Control Board and recreation area managers to notify the public and post advisory signs at affected waterbodies. To learn more about HABs, or to report a HAB, visit the Water Board’s website. Blue-green algae (cyanobacteria) is a natural component of ecosystems. Under certain conditions, including warmer temperatures and increased nutrient loads, algae can grow rapidly causing “blooms.” Algal blooms sometimes produce toxins that can be harmful to people and animals. Visit this comparison chart on the HABs website for additional information. CURRENT LAKE OPERATIONS The elevation of Oroville’s reservoir is about 709 feet elevation and storage is about 1.32 million acre-feet (MAF), which is 38 percent of its total capacity and 63 percent of historical average. Temperatures are forecasted to be in the low 90s through the weekend and increasing to the upper 90s and low 100s next week. The Feather River releases are currently at 3,000 cubic feet per second (cfs) to meet downstream Delta water quality and outflow needs. Flows through the City of Oroville are 1,000 cfs with 2,000 cfs released from the Thermalito Afterbay Outlet (Outlet) for a total of 3,000 cfs downstream of the Outlet. Flows through the low flow channel may be reduced next week for fisheries purposes. The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center at www.cdec.water.ca.gov. The Lake Oroville gage station is identified as “ORO”. All data as of midnight 8/25/2022 California is in its third year of drought conditions. With water conservation now a way of life in California, everyone is encouraged to find ways to save water.
