Yuba Accord Implementation Monitoring and Evaluationg

2001 - 2004 – Technical Team developed Yuba Accord flow schedules, including water temperature considerations for Chinook salmon and steelhead.

2006 2007 Yuba Accord implemented on a “pilot program” basis including water2006 – 2007 – Yuba Accord implemented on a pilot program basis, including water temperature and fisheries monitoring.

2008 – SWRCB issued water right orders for the long-term implementation of the Yuba AccordAccord.

• Establishment of the Yuba Accord RMT• Yuba Accord M&E Program implemented

2008 through 2011 RMT published annual reports describing individual year results2008 through 2011 – RMT published annual reports describing individual year results.

2010 – RMT evaluated the Yuba Accord Water Temperature regime since 2006 and published the results.

2012 – RMT began evaluating multi-year trends and preparation of the MONITORING AND EVALUATION PROGRAM INTERIM REPORT.

Developing, testing & deploying new data collection techniques

Acoustic Tracking

Vaki Counterg Fixed, and finite, stationary receivers No directional ability

Redd Sampling

Time lag from lower river or Daguerre Pool holding

Imperfect photos thus species capture (although getting better)p g

Platform challenges (kayak, pontoon, deep water camera)

(although getting better)

M&E Interim Conclusions

The lower Yuba has highly functional spatial structure Diverse & Persistent Recurring functional flows Natural, complex river morphology

I l t ti f th A d id it bl fl Implementation of the Accord provides suitable flows and temperatures for all life stages for anadromous salmonids

The Lower Yuba has good habitat conditions Abundance of available, suitable habitats

The lower Yuba is ‘attractive’ (from standpoint of habitat) relative to other rivers

DIVERSE PATTERN OF MOVEMENT AND HOLDING

• Most but not all fish migrate upstream ofMost, but not all, fish migrate upstream of Daguerre Point Dam

• Some fish migrate downstream, including into the Feather Riverinto the Feather River

• Daguerre Point Dam to the SR20 Bridge largely used as a migratory corridor

• Protracted temporal migrations to areas upstream of the SR20 Bridge

• Prolonged occupancy in pools throughout the river

• Extended holding in the Daguerre Point Dam plunge pool and the Narrows pool
