The California Department of Water Resources begins the first water release from the Lake Oroville flood control gates down the main spillway in Butte County, California. Main spillway releases will continue to manage lake levels in anticipation of rain and snowmelt. Photo taken January 31, During the winter months, releases from Lake Oroville provide flood protection to downstream communities by maintaining storage capacity in the reservoir for additional rain capture. DWR coordinates releases closely with the U.

Officials have stopped water releases at the Lake Oroville dam as of Wednesday morning following nearly a week of outflow that equated to billions of gallons of water leaving the lake. California's Department of Water Resources DWR opened the main spillway at Oroville Dam last Wednesday to provide flood protection for downstream communities in advance of two atmospheric rivers that were set to batter the state with torrential rain. Lake Oroville's water levels had jumped significantly in advance of the storms, but the storms have since passed and Lake Oroville's water release through the main spillway has now stopped. A DWR spokesperson told Newsweek an estimated 62, acre-feet of water were released through the spillway while it was open. Lake Oroville is currently at 77 percent of storage capacity. The lake rose by 15 feet in the last two weeks of January, but since the release began last week, the levels have since stalled around feet. The lake is 56 feet below full pool, a much-improved state over the summer of , when the lake reached concerningly low levels. The lake is 28 feet higher than it was this time last year, and 97 feet higher than it was in February In a follow-up post, the DWR said that water released into the Feather River supports the environment, with some of the water flowing downstream to the San Luis Reservoir, "where it is captured to maintain overall water supply. A similar release occurred at Pyramid Dam on Monday when water officials chose to release excess stormwater associated with the atmospheric river. Oroville Dam spillway releases could increase in the future, but the DWR spokesperson told Newsweek the decision to open the spillway was "entirely weather dependent. Lake Shasta, also in Northern California, has risen significantly since the beginning of the year , and water officials also are managing Lake Shasta to mitigate flood risk.

A record wet season has led to California's second-largest reservoir filling up. California's Lake Oroville, one of the many important reservoirs in the West that reached critically low levels during the height of the megadrought, is now filled to the brim. Before and after images of Enterprise Bridge offer a sharp comparison for Lake Oroville between July 22, , and June 15, , after the reservoir, the second-largest in the state, reached full pool for the first time since -- and only the second time in the past 15 years, according to the California Department of Water Resources. In September , water levels in Oroville dipped to their lowest ever at As of Monday, water levels neared feet -- more than feet higher than this time last year. Storage at Lake Oroville has risen more than feet and gained more than 2. The improving drought conditions in California are "a stark difference" from the last three years, California Department of Water Resources director Karla Nemeth said in an emailed statement to ABC News.

Photo taken July 3, Total releases to the Feather River amount to 5, cubic feet per second cfs , with adjustments being made as needed. Over the past week, inflows into Lake Oroville have been in the range of 2, to 3, cfs and are projected to be lower for the coming week. DWR will use the main spillway for water releases through early next week to manage storage within the Oroville complex and maintain Feather River temperature levels during river valve outlet system work near the Hyatt Powerplant. When the main spillway is not in use water may still be seen on the main spillway outlet as the seals on the eight radial gates are not designed to be watertight. The gate seals do not play a role in the structural integrity of the gates, which continue to operate as intended. DWR periodically maintains and adjusts the seals during low-reservoir conditions to improve their sealing capability. The radial gates were also last inspected and tested in Dec. Visitors to Oroville Dam may also notice minor amounts of water flowing from drains built into the emergency spillway. As the reservoir level has increased, water flow from the drains has increased, which is normal and expected with the emergency spillway design.

Last year, Lake Oroville hit its maximum capacity of feet by June. On March 4, , the lake was at feet in elevation but this year, on the same date, Lake Oroville sat at feet. Raquel Borrayo, a spokesperson with the California Department of Water Resources, said releases are continuing from the Oroville Dam's main spillway as well as other channels. Releases from the main spillway vary throughout the day depending on the availability of the Hyatt Powerplant for flood protection releases. DWR continues construction work on a River Valve Outlet System project, restricting Hyatt Powerplant operation to the evening and weekend hours for the safety of construction crews. Borrayo said the releases will continue from the lake in an effort to prevent flooding, adding that the amount released is based on guidelines from the U. Army Corps of Engineers and other water operators and adjusted as needed to account for continuing runoff," Borrayo said. While the state's snowpack had a rocky start to the year with extremely limited snow, DWR's latest survey on Feb. When the weather begins to stay consistently warmer, the snow melt-off begins to reenter the waterways, often prompting DWR to release additional water from the lake. Meanwhile, Shasta Lake sits at just shy of 1, feet as of Monday, a drop from 1, feet at its peak so far for this year on Feb.
