Colorado is pleased to provide the following information in support of the Reservoir Coordinating
Committee (RCC) for the three state Platte River Cooperative Agreement. In preparing the
information we focused our efforts on the South Platte River and select data which we believe is the
most relevant for the RCC. We have also included a number of Internet Sites which people can
access for additional information and up-to-date information over the next several months.
II. WATER SUPPLY OUTLOOK

Attached are several graphs of historic and current (March 2002) flow information for the South
Platte River at Julesburg. The mean daily flow for the South Platte at Julesburg for March 2002 and
for the period of record (1902-present) is 190 cubic feet per second (cfs) and 563cfs, respectively
(see Figures 1 and 2).
Figure 2 shows South Platte mean monthly flows at Julesburg. A composite of the minimum and
mean monthly flows for the period of record 1902-1998 is also included to provide the reader with a
sense of the wide range of flows which can be expected. As shown on the graph the average flow at
Julesburg is much below average for this water year versus the period of record.
Figure 3 shows predicted stream flow in Colorado as of April 1. Unfortunately, you will note that
all of Colorado is much below average (50 to 70 percent of average) or extremely below average
(less than 50 percent of average).
