IBCC Meeting Notes May 9 2007

• Title: Meeting Notes
• Date: 5/9/2007
• Interbasin CC - Doc Type: Meeting Notes

have talked about previously – a consumpt ive and non - consumptive work group . We
a ls o have a presentation from the M etro roundtable. After the legislative session, we will
hold our IBCC meetings across the state in order to hear from and get input from all of
the roundtables. We are here in Den ver to be with the Metro Roundtable. Representative
Curry said it well last meeting, that one thing we need to do is really understand what’s
going on from the perspective of each basin. Finally, we will get an update on the Water
Supply Reserve Account and discuss its continued implementation.

Colorado River Basin Activities and Issues

To begin discussion on Colorado River Basin Activities and Issues, CWCB Executive Director
Rod Kuharich gave a brief introduction, summarized below.

Rod Kuharich: CWB C will be conducting a study on the Colorado River , as outlined in
the Projects Bill . We have a real opportunity to get input for this study to make it the best
it can be. Our schedule is to begin scoping issues and study methodologies in early June.
CW CB will convene a management team with both internal and external membership.
We will also involve all basin roundtables in our process. We’re here today to get input
from you on the focus of the study and potential methodologies. Since we’re just
begin ning, we have to rely on what historical data there is out there to determine how
much water is available in the River. We are looking at doing a sensitivity analysis under
various climatological conditions so that we can do analysis without attributing c limate
a ffects to various activities. This s ensitivity analysis will give us a range of flows to
analyze, which we hope will equate to flows we may see in future years. To do this we
will need to consider and include the needs assessments, SWSI work, inf ormation on
draug hts, water rights, ESA, etc. – a ll will come to bear on water availability. As we go
further into the process today, what we would like to have is input from this group on the
process and methodology for the study as well as technical iss ues. We realize there is
much more to this than what we will talk about today. Many of us feel overuse by the
Lower Basin is directly impacting Upper Basin. There is also a role for the Upper Basin
Commission on decision making on the Colorado.

Melind a K assen: I have a question about the time frame. How does the study fit with
needs assessments being conducted in individual basins, especially if they will not be
done until a much later time?

Rod K uharich: We we re asked to recommend to the L egislature to phase the study
process. This will allow for needs assessments to be completed and that data to be
incorporated into the study. We d o not have a deadline from the L egislature for the study
process.

Following Rod’s presentation, Dan McAuliffe and Randy Seaholm presented several slides with
questions about the study, summarized below. The presentation is available separately on the
website.
