Wow! Cool

And for the CR Climate and Hydrology work group- as a reminder, we have funded a project with Ethan Gutman and Ryan Currier to look at ICAR/En-Gard projections for the Colorado River!

I.e. New isn't necessarily better for the Colorado River!

Also- We will be making recordings and presentations available on the WUCA website soon!

Given that the CMIP3/CMIP5 show wetter conditions than Stress Test or Millenium Hydrologies, what is the benefit of using them for planning purposes?

I liked Jim's comment re: using, or not using, Median values to represent CMIP hydrology's, any thoughts as to how to communicate CMIP results away from statistics? We get stuck showing them with the other hydrology's, but it's a communication barrier in trying to explain that the median of the natural flow record is not really the same as the median of the CMIP3 (or that the 10-90% envelopes are also communicating different information).

Great question Rich, This is what I was getting at with my question to Jim when he showed all the 2 GCM hydrologies next to the others. I was very interested in hearing that the GCMs hydrologies are rosier than the " new normal" hydrology.

And 2nd, has Reclamation culled to different emission scenarios? I believe Joel touched on it yesterday, that RCP 8.5 seems to be less realistic, so has CMIP3 or CMIP5 been evaluated without using those RCPs? In general, culled down to I think 148 projections still feels like a lot to me

Please continue to put the poll links in the chat

Low Lake level pump station allows us to pump water when lake Mead is below 1,000 ft. Down to 895 feet.

Which methods did you use to estimate the reduced water demand that you could achieve with these interventions?

Thank you Zane!

Please submit any questions you have for the panel in the chat! We have a few minutes or additional questions if you have them.

We're in the midst of a mega-drought which the science is showing is being made worse by climate change. What happens if we get a wet period for a few years? Let's say the years 2025-2030 is dominated by El Nino conditions that should result in higher levels of precipitation in the southwest (with the amount of precip juiced by higher temperatures). Knowing that we do not expect conditions to stay wet, i.e., droughts will return, how would you manage public expectations and keep the eye on the likelihood of longer term drying?

In what ways do your organizations collaborate with local land use planners and the development community on understanding how the built environment impacts water demand and making code/zoning changes accordingly? (Im a land use planner in Tucson, we are starting climate-adapted code updates in the near future)

For Brandon- is California planning on desalination plants and how does that fit in the various models?

Thank you so much Rebecca!

Thanks Rebecca!

Thank you all!

Great morning, thank you!

Thanks!
