Thursday

A few Workshop Highlights:

Chinook Salmon

River

Estuary

Ocean

• Ocean, river, estuary conditions all matter –the 4 H’s: hydrology, harvest, hatcheries, and habitat (J. Israel & R. Johnson, Reclamation and S. Lindley, NMFS)

• Survival of migrating juveniles is getting worse - best in North Delta/ Sacramento River (up to 70%), poor in Central Delta (down to < 10%, Russ Perry & Jon Burau, USGS), and poorest in the South Delta/San Joaquin River (often <10%, Pat Brandes, FWS)

• Survival is generally greater at higher flows (several talks). Duration of flow direction may be important metric (B. Cavallo, Cramer Fish Sciences)

• The Sacramento River banks near the city of Sacramento are “lined” with predators (>3 per 100m) – tethered salmon smolts had a 31% chance of being eaten in one hour (Cyril J. Michel, NMFS)

• Review of IEP Delta Juvenile Monitoring & Survival Studies – Public scoping meeting May 11 (J. Kirsch, FWS)

Brief FLaSH History & Timeline2008 – New FWS Delta Smelt BiOp with prescription

to adaptively manage fall outflow in W & AN years2009 – Habitat Study Group2011 – April – Wet Year designation

• May – Prepared draft AMP• June – Review panel convened by DSP• July – Panel report and AMP revisions• August — FLaSH Preparations• September – Implementation

2012 – Next review in July – 1st FLaSH report• Study continuation, maybe some new studies


FLaSH Terminology• FLaSH: Fall Low Salinity Habitat• X2: distance of salinity 2 from Golden Gate in km• Low salinity zone (LSZ)

– 1-6, where most delta smelt occur in the fall

• Low salinity habitat (LSH)– Includes other stuff that organisms need
