Update on model modification proposal for Managed Wetland Trophic Subsidies (rice field food) (Brett)

  • Review of conceptual mixing rate of food sources into mainstream river segments.
  • Built a mixing model.
  • Question: how fast does mixing occur?
  • Example: Knights Landing mixing observable on Google Earth
  • Errors came down to visual errors on documenting full-mixing.
  • Back calculated from full mixing to food mixing
  • Russ Perry bio-physical model based on hatchery growth rates / temperature / rations
  • Nags data + suisun growth rates. Also cage fish measurements upstream / down stream of sources.
  • Finding density that represents saturation ration.
  • Should be able to assign higher growth rates
  • Question: what about saturation level through time? Is there a relationship between number of fish and removal of food because of consumption?
  • Assume dilution is primary driver
  • What about good holding habitat?
  • Don’t consider thalweg to be good habitat for holding salmon
  • Need to assume food directed at margins
  • Would it make sense to expand from linear distance?
  • Proxy estimate good for now. Some rivers would have more definition.
  • Assuming mixing is linear, but really more complex mixing.
  • Intention to develop initial operation, then expand to other streams as appropriate.
  • Acres flooded to numbers of fish affected. Could result in changed growth rates or different growth matrices. Initial results are greater than current Perry estimates.
  • Question: why not just implement Rene’s idea out of the box?
  • Will follow-up off line

Status of Science Coordinator (Cesar)

  • No significant update from last call.
  • Announcement sometime in August

Discuss where we are now and where we are going

  • Review slides from draft implementation plan cross-walked with current status
  • Presentation Slides
  • Near Term 5 Year Restoration Strategy
  • Schedules and updates reflected in slides
  • SIT likely to meet less often
  • Science coordinator outreach and review in year 4 of 5
  • Benchmark schedule from 2017. Now pushing things back
  • Contracting issues delayed watershed meetings and participation by Adam and Jim
  • Revised timelines
  • Would be helpful to have interim science coordinator to write up tech memo
  • Would like to continue to develop subgroups to consider habitat decay stuff
  • Would be nice to continue to develop time per unit effort to justify strategy rates
  • Relationship to Salmon Partnership and CAMP? When would these be done?
  • Assume we will be talking about acreage increases across habitat types.
  • When would we need something? Probably October of this year after AFS meeting
  • Who is keeping track of the monitoring in order to answer questions
  • Working on draft data guidance. Lots of data is stovepiped. Looking to organize the monitoring team.
  • How will we correlate and coordinate data
  • Develop broad agreements about monitoring reviews

A quick review of the Near-term Restoration Strategy development (Jim and Adam)

  • Reclamation has been meeting with Commissioner regarding CPAR
  • Assumption that CPAR list will be updated to replace outdated projects with current priorities from near-term restoration actions

Using the DSMs to develop the strategy (Jim and Adam)

Status of the Chinook and O. mykiss DSMs (Jim and Adam)

  • How to efficiently develop calibration?
  • Coordination with FlowWest to talk

Status of watershed expert meetings (Mike U.)

  • September 9 in Lodi
  • Red Bluff and Sacramento dates pending
  • Modeling 101 still under development

Status of the habitat decay proposal (Rod)

  • Everyone has been on leave, nothing to report

The role of the SIT after the Near-term Restoration Strategy (Cesar, Heather, and Rod)

New Business

  • Draft Data Guidance should be available soon
  • Expert elicitation could include customers / stakeholders. What level of detail would be appropriate
  • See cvpia.scienceintegrationteam.com
  • Notes from chat:

The Role of the Sit after NTRS Monitoring direction - improvements - data gaps Feedback loop - Hindcast completion and monitoring of recent projects Incorporate new sub-models - e.g. Habitat Decay; Rice Field Food; etc. Revisit - Revise DSMs Peer Review Revisions to NTRS - Schedule & Purposes - what needs fixing/modification first?

From Rod Wittler to Everyone: (10:43 AM) CPAR and the Strategy: Evaluate remaining 81 CPAR actions in context of NTRS Replace CPAR actions with NTRS actions by EOY 2019

From Rod Wittler to Everyone: (10:54 AM) 3 sets of charters/projects to collect feedback from: Those in the pipeline already (thru FY19) Historical (Hindcast) 2020 and beyond - those generated by the NTRS

From Sadie to Everyone: (10:57 AM) http://cvpia.scienceintegrationteam.com/meetings/
