| Abstract: | On November 21, 2007, National Marine Fisheries Service (NMFS) issued a long-term biological opinion (BO) regarding the U.S. Army Corps of Engineers’ (Corps) operation and maintenance of Daguerre Point and Englebright dams (NMFS, 2007). On December 20, 2011, the U.S. District Court ordered NMFS to file a new BO by February 29, 2012. The new BO, dated February 29, 2012, included an incidental take statement with several terms and conditions. Term and Condition D3 of the BO requires the Corps to “develop and implement a long term program to replenish instream woody material” (NMFS, 2012). In anticipation of Term and Condition D3, the Corps has prepared the Lower Yuba River Large Woody Material Management Plan (LWMMP), which includes the implementation of a Pilot Study starting in 2012 in order to enhance rearing conditions for spring-run Chinook and Central Valley steelhead (Corps, 2012). In accordance with BO Incidental Take Statement Term and Condition D3a, the Corps proposed to initiate a pilot study to determine an effective method of replenishing the supply of large woody material (LWM) back into the lower Yuba River. As described in the LWMMP, the Pilot Study will use LWM from existing stockpiles at New Bullards Bar Reservoir for placement at selected sites along the lower Yuba River. The Pilot Study would include monitoring of placed materials. The Pilot Study will be evaluated to assess the effectiveness of LWM placement in the lower Yuba River in order to develop a long term program (Corps, 2012). If significant changes to the LWMMP are proposed as a result of lessons learned from the pilot study for the broader management plan, appropriate supplemental environmental documentation will be produced. |
