  • NMFS 2014 Biological Opinion for Daguerre Point
    UNITED STATES DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration NATIONAL MARINE FISHERIES SERVICE West Coast Region 650 Capitol Mall, Suite 5-1 00 Sacramento, California 9581 4-4 700 In response refer to: MAY 1 2 2014 WCR-2013-1 Michael J. Farrell Colonel, U.S. Army Commander U.S. Army Engineer District, Sacramento 1325 J Street Sacramento, California 95814-2922 Dear Colonel Farrell: This document transmits NOAA's National Marine Fisheries Service's (NMFS) biological opinion (Enclosure) for the U.S. Army Corps ofEngineers' (Corps) operation and maintenance ofDaguerre Point Dam on the Yuba River. The biological opinion reviews the effects of the action on federally listed threatened Central Valley spring-run Chinook salmon (Oncorhynchus tshawytscha), threatened California Central Valley steelhead (0. myldss), the threatened Southern distinct population segment of green sturgeon (Acipenser medirostris), and their designated critical habitat in accordance with section 7(a)(2) of the Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531 et seq.). On August 13, 2013, the U.S. District Court, Eastern District of California, ordered NMFS to file a new biological opinion by May 12, 2014. Your request for reinitiation of formal consultation, which included the final biological assessment, was received on October 22, 2013. The proposed action is the Corps' continued operation and maintenance ofDaguerre Point Dam on the lower Yuba River. Operation and maintenance at Daguerre Point Dam includes operation of the fish ladders (flow gates, baffle boards, debris removal), sediment management, flashboard management, a river stage gage, a contract for operation of fish counting system in the fish ladders and a contract for the installation of flashboards on the dam.

  • Deep Storage of Contaminated Hydraulic Mining Sediment Along the Lower Yuba River, California
    Nakamura, TK, et al. 2018. Remains of the 19th Century: Deep storage of contaminated hydraulic mining sediment along the Lower Yuba River, California. Elem Sci Anth, 6: 70. DOI: https://doi.org/10.1525/elementa.333 RESEARCH ARTICLE Remains of the 19th Century: Deep storage of contaminated hydraulic mining sediment along the Lower Yuba River, California Tyler K. Nakamura*, Michael Bliss Singer†,‡ and Emmanuel J. Gabet* Since the onset of hydraulic gold mining in California’s Sierra Nevada foothills in 1852, the environmental damage caused by displacement and storage of hydraulic mining sediment (HMS) has been a significant ecological problem downstream. Large volumes of mercury-laden HMS from the Yuba River watershed were deposited within the river corridor, creating the anthropogenic Yuba Fan. However, there are outstanding uncertainties about how much HMS is still contained within this fan. To quantify the deep storage of HMS in the Yuba Fan, we analyzed mercury concentrations of sediment samples collected from borings and outcrops at multiple depths. The mercury concentrations served as chemostratigraphic markers to identify the contacts between the HMS and underlying pre-mining deposits. The HMS had mercury con- centrations at least ten-fold higher than pre-mining deposits. Analysis of the lower Yuba Fan’s volume suggests that approximately 8.1 × 107 m3 of HMS was deposited within the study area between 1852 and 1999, representing ~32% of the original Yuba Fan delivered by 19th Century hydraulic gold mining. Our estimate of the mercury mass contained within this region is 6.7 × 103 kg, which is several orders of magnitude smaller than what was estimated to have been lost to the mining process.

INTRODUCTION: The State Mining and Geology Board (SMGB) is the lead agency pursuant to the Surface Mining and Reclamation Act (SMARA) for the County of Yuba. On August 6, 2009, the SMGB commenced the special public hearing to determine whether Western Aggregates, LLC. (Western) had vested rights for 4,125 acres, which included its current surface mining operations, located in the Yuba Goldfields. At its public hearing held on September 11, 2009, the SMGB accepted the findings set forth by the California Geological Survey (CGS), and determined that a preponderance of evidence existed that demonstrated Western has vested rights for all Sections with exception to Sections 25 and 30, and the southwest corner of Section 34. The SMGB at its February 11, 2010, regular business meeting considered limitations in terms of annual production associated with this determination of vested rights, and determined that no limitations or restrictions on annual production would be imposed.

SUMMARY The Yuba River is located on the west slope of the northern Sierra Nevada and is a tributary to the Feather River. It pours down 3 main stems (South, Middle, and North) from granitic basins through forested canyons to the Sacramento Valley. The watersheds for the South, Middle, and North Yuba Rivers are impacted by a variety of human activities, while the rivers themselves are some of the most regulated in the state (in terms of flows).
