Lower Yuba River Accord Monitoring and Evaluation Program and Interim Report Overview Gary Reedy South Yuba River Citizens League Lower Yuba River Symposium June 12, 2013 1
Requirements of the Yuba Accord Fisheries Agreement (2005) Monitor and evaluate “the effectiveness of the implementation of the Lower Yuba River Accord” Evaluate “the condition of fish resources in the Lower Yuba River” Evaluate “the viability of Lower Yuba River fall-run Chinook salmon and any sub-populations of the Central Valley steelhead and spring-run Chinook salmon Evolutionarily Significant Units (ESUs) that may exist in the Lower Yuba River” Monitoring & Evaluation Program 2
M&E Program Goals and Framework EVALUATE WHETHER OR NOT THE IMPLEMENTATION OF THE YUBA ACCORD . . . Maintains Fish in Good Condition Fish and Game Code § 5937 Promotes Viable Salmonid Populations NMFS Recovery Assessment M&E Plan Structure: IDENTIFY AND EVALUATE . . . • Establish Performance Indicators Flow and Water • Identify Data Requirements Temperature Relationships with • Define Analytics Fish Populations • Examine Relationships Between Aquatic Habitat Attributes Measures of VSP Parameters and Flows and Water Temperatures 3 Monitoring & Evaluation Program
Re-framed M&E Program Goals • Evaluate the condition and viability of fish populations in the lower Yuba River • Identify and evaluate relationships between flow and water temperature and … • Fish populations • Aquatic habitat attributes • Determine whether the Yuba Accord flow schedules provide conditions that are protective of the fishery resources of the lower Yuba River • Maintain physical habitat attributes that provide opportunity for good condition of aquatic resources and viable salmonid populations.

Yuba Accord Implementation Technical Team Draft Yuba SWRCB issued RMT RMT begins developed Yuba Accord Accord signed by water right published multi-year flow schedules, including YCWA, resource orders; official Final M&E trend water temperature agencies, PG&E implementation Frame- evaluation for considerations and NGOs of the Yuba work M&E Report Accord (2001 – 2004) 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 Water RMT published Yuba Accord Temperature annual reports implemented Objectives describing on a “ pilot Memorandum individual year program ” basis results (2006 – 2007) (2008 – 2011) 6 Monitoring & Evaluation Program
Draft Interim Report (April 2013) M&E program is scheduled and funded to run through at least 2015. Interim Report is a ‘report card’ on implementation of the Yuba Accord For regulators, stakeholders and the broader scientific community To inform the relicensing process before the Federal Energy Regulatory Commission currently underway for YCWA facilities in the Yuba River Watershed (the Yuba River Development Project, FERC Project No. 2246) The RMT will seek input and comment from the scientific community in order to refine the work planned for the next few years, and hopefully beyond. Available for review through July 12. www.yubaaccordrmt.com 7 Monitoring & Evaluation Program
