  Main Spillway Releases Ongoing As snowmelt season begins, the Department of Water Resources (DWR) continues to perform flood protection releases from Lake Oroville using the main spillway and Hyatt Powerplant. Releases from Lake Oroville during the spring months help maintain storage capacity in the reservoir to capture runoff from mountain snowmelt, while optimizing storage for the benefit of water supply, recreation, and fish and wildlife enhancement. DWR coordinates releases closely with the U.S. Army Corps of Engineers and other water operators and adjusts releases as needed to maintain balance throughout the water system. The information below reflects current reservoir level estimates. Forecasts can change quickly and may affect the estimates provided.
Lake Oroville is the largest storage facility in the State Water Project, providing flood protection while supporting environmental and water delivery needs to 27 million Californians. In 2023, Oroville Dam’s main spillway passed over 2,370,000 acre-feet of water, 67 percent of Lake Oroville’s capacity, with flows as high as 36,000 cfs. The main spillway continues to perform well and operate as designed. DWR continues to monitor lake levels, weather forecasts, and mountain snow levels to optimize water storage while meeting environmental requirements and allowing for carryover storage into next year.  OROVILLE WILDFLOWER & NATURE FESTIVAL The Feather River Recreation & Park District (FRRPD) is hosting its annual Wildflower & Nature Festival at Riverbend Park in Oroville on Saturday, April 6 from 10 a.m. to 4 p.m. Admission is free to the festival with activities highlighting the area’s natural resources and booths showcasing handmade Butte County products.

DWR, the California Department of Parks and Recreation, and the California Department of Fish and Wildlife (CDFW) 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. Lake Oroville is one of the State Water Project’s premier recreational destinations and one of California’s best fishing spots. The lake provides both warm-water and cold-water fisheries and is a popular destination for bass tournaments. Below the Oroville Dam, the Thermalito Afterbay and the Feather River offer additional excellent fishing opportunities. 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. Upstream migrating fish totals through the Feather River Fish Monitoring Station between Jan. 1 and March 18 are:
CURRENT LAKE OPERATIONS Lake Oroville is at 870 feet elevation and storage is approximately 3.08 million acre-feet (MAF), which is 87 percent of its total capacity and 124 percent of the historical average. Feather River flows are at 1,000 cfs through the City of Oroville with 9,000 cfs being released from the Thermalito Afterbay River Outlet (Outlet) for a total Feather River release of 10,000 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 3/28/2024. Comments are closed.
