News Release
CALIFORNIA DEPARTMENT OF PARKS AND RECREATION Divisions of Boating and Waterways, Historic Preservation and Off-Highway Vehicles News Release For Immediate Release Contact: Apr. 5, 2017 Aaron Wright Sector Superintendent [email protected] (530) 538-2200 Summer Recreation at Lake Oroville State Recreation Area OROVILLE, Calif. -- The emergency effort to repair the Lake Oroville spillways will not interfere with most outdoor recreation this summer at the lake, and with the exception of the Spillway Boat Launch Ramp, all boat launch ramps are open, announced California State Parks (DPR) and the Department of Water Resources. All campgrounds also are open and floating campsites are back on the lake and available for rental. Some areas near the dam will continue to be off-limits to visitors as crews work to repair or replace spillways damaged in February during high runoff. Outdoor activities available at Lake Oroville this summer include: Campgrounds: All campgrounds are now open with site-specific reservations available at Bidwell Canyon, Loafer Creek and Lime Saddle. Campers without reservations are still welcome on a day-to-day basis to any campsites that have not been previously reserved. Campground showers have been equipped with token machines. Each site will have a unique, collectable token which can also be used at other participating state parks. Trails: Lake Oroville has a number of trails for hiking, biking and equestrian use. Trails around the Diversion Pool and Hyatt Power Plant likely will be closed throughout the summer, although DPR may make changes to other trails to accommodate more hikers and help compensate for the closures.

Sacramento and Feather Rivers and Their Tributaries, Sacramento Slough and Sutter Bypass
Section 319 NONPOINT SOURCE PROGRAM SUCCESS STORY Stakeholders Cooperate to ReduceCalifornia Diazinon in Runoff from Dormant Season Spray Widespread use of the organophosphate (OP) pesticides diazinon Waterbodies Improved and chlorpyrifos in California’s Central Valley resulted in aquatic toxicity in the Sacramento and Feather rivers and their tributaries, Sacramento Slough and Sutter Bypass. As a result, in 1994 the Central Valley Regional Water Quality Control Board (CV-RWQCB) added a 16-mile segment of the Sacramento River, a 42-mile segment of the Feather River, the 1.7-mile-long Sacramento Slough, and the 19-mile-long Sutter Bypass to the CWA section 303(d) list of impaired waters. In 2001, the Sacramento River Watershed Program (SRWP) developed and implemented a water quality management strategy for the two rivers, which included installing on-site best management practices (BMPs). Diazinon concentrations decreased, prompting CV-RWQCB to remove Sacramento Slough and Sutter Bypass from the CWA section 303(d) list in 2006. The state has recommended the removal of the Sacramento River and Feather River segments (58 river miles total) from the 2010 CWA section 303(d) list for diazinon impairments. UV162 Figure 1.

A unique aspect of this incident was the fact that it happened during a ﬂood scenario well within its design and operational procedures, prompting research into its causes and determining methods to prevent similar events from reoccurring. In this study, a hydroclimatic analysis of Oroville Dam’s catchment is conducted, along with a review of related design and operational manuals. The data available allows for the comparison of older ﬂood-frequency analyses to new alternative methods proposed in this paper and relevant literature. Based on summary characteristics

There, one of the world's largest dams rose across one of California's smallest creeks. The American mantra of "bigger is better" captured the spirit of the times when the San Luis Unit

Appendix H. Lake Davis, CA, Rotenone Application
Appendix H. Lake Davis, CA, Rotenone Application The information contained in this summary was provided by the California Department of Fish and Game (California Department of Fish and Game, 1999). In October 1997, the California Department of Fish and Game treated Lake Davis in Plumas County, California, with rotenone to eliminate introduced Northern pike (Esox lucius) that was considered a predatory fish, potentially threatening indigenous salmonids and other threatened and endangered fish species in the Sacramento-San Joaquin Delta (personal communication: Brian Finlayson, California Department of Fish and Game 2005). Located at an elevation of 5,775 ft above mean sea level, Lake Davis is a 4,026 acre (1,619 ha) impoundment of Big Grizzly Creek, a tributary to the Middle Fork Feather River. The reservoir has a maximum depth of 108 ft (33 m) and a mean depth of 20.5 ft (6.3 m) (Lee, 2001). The reservoir is classified as meso-eutrophic based on growing season inorganic nitrogen concentration (Lee, 2001). From October 15 - 16, 1997, the Lake Davis and its tributaries (Grizzly, Freeman and Cow Creeks) were treated with two formulations of rotenone, i.e., 64,000 lbs of powdered ProNoxfish (7.1% a.i.; EPA Registration No. 432-829) and 15,785 gallons of a synergized liquid formulation Nusyn-Noxfish (2.5% a.i.; EPA Registration No. 432-550) to maintain a desired treatment concentration. The liquid formulation used piperonyl butoxide as a synergist. Rotenone concentrations were measured within and surrounding the treatment area. The data suggest that initially rotenone was not equally distributed through the water column; this is consistent with the reservoir having an average depth of roughly 20 feet.
