SLJBJECT: Summary of Select Water Storage Information and
Flow Condition for the South Platte River Basin
1. INTRODUCTION
Since the last RRC/EAC meeting, the three States and the U.S. Departmcnt of the Interior have
continued implementing the Platte River Endangered Species Recovery Implementation Program
Agreernent ("the Program"), which began on January 1, 2007.
Please see the following information in support of the RRC and EAC meetings for the Program.
In preparing the information I continued to focus my efforts on the South Platte River and
selected data, which I believe is the most relevant for the RCC. As always, I have also included
a number of Internet Sites, which people can acccss for additional information and up-to-date
information over the next several months. As the State of Colorado is working to have the
in&astructure in place to retime up to 5,000 acre-feet of water at this time next year, the fall 2008
(and/or possibly the spring 2009) report may look substantially different than this report,
depending in part on how the EA manager would like to work with Colorado to revamp this
annual report.
H. WATER SUPPLY OUTLOOK
Stream Flow
I have attached several graphs of historic and current (March 2008) flow information for the
South Platte River at Kersey and Julesburg. Of note, on the first table, the streamflows at Kersey
are substantially lower than this time last year, but approximately about average. The flows at
Julesburg are higher than this time (ast year, but much lower than the long-term average flows at
Julesburg. (See pages 3-8). With the entire State above average for Snowpack and the South
Platte Basin slightly above average, we are expecting a slightly higher than average runoff. In
addition, most of the reservoirs are a better position than over the last several years.
Reservoir Storage
A summary of the status of select reservoir storage and reservoir capacity is provided in the
attachments, pages 9-12. Because the amount of precipitation in the South Platte River basin
