. Wllter Management Study Update: The reconnaissanpe level study of water management and
storage sites in the iower South Platte basin officially got Wlderway on January 5, 2001. The study
area will focus on potential water management opportunities from approxin3ately the Tamarack
Ranch State Wildlife Area to the Colorado-NebraSlca state-line. The study is intended to provide
information that will assist in identifying surface stora~ structures that could facilitate Colorado's
management of South Platte River flows, includillll coordination with ground water recharge
proj ects, for in-state beneficial uses, such as water rightiand South Platte River Compact
administration and providing benefits for biological spebies of concern in Colorado, and for
participation in an endangered species program being d~veloped pursuant to the Platte River
Cooperative Agreement. .

Our consultant, GEl Inc. has completed an initial review of existing infonnation and has completed
some work on water availability. Approxin3ately 17. potential storage sites have been identified
ranging in size from approximately 1,000 to 21,000 acte.feet. We have also developed preiiminary
screening criteria that will be used to obtain a "short list" of the most promising sites.

As expected our initial challenges appear to be rel~ed to fill and release logistics, and moderate to
high ratios for embankment voiume to water storage vdlume. A meeting with our stakeholder
group will be scheduled in the next few weeks to <liscu$s initial results and obtain feed back on the
preiiminary screening criteria. We plan to have a draftifinal report in May 2001.

Dry Creek Flood Control Project: A $50,000 grant from the construction fund was approved
by the Board in January for Larimer COWlty for II feasibility study related to the multi..million
dollar flood control project on Dry Creek. The projeyt would remove a substantial amoWlt of
homes and property from the regulatory 100-year flOiJdplain. The CWCB Flood Protection
Program staff is working closely with the Water Suppiy Planning and Finance Section staff,
along with the project sponsors, to develop a cOIhpre~ensive scope of services for completion of
the Dry Creek feasibility study.

Cherry Creek Site Specific PMP Study: The kickoff meeting was held Feb. 2 at the Urban
Drainage and Flood Control District Office. ApPlied:Weather Consultants, Ed Tomlinson
presented an overview of the project, work task and performance schedules for the study team.
We have cooperation from the Army Corps ofBngin~ers, however, the Corps has requested that
we officially request backgroWld information and te~hnical data. A simiiar procedure is likely
with the National Weather Service. The CWCB proposed the concept of a three-member
Technical Review Panel to review work products at intervals during the project. Additional
meetings will be scheduled for the technical review panel and five more work group meetings
are scheduled for this year. A final report is due Dec: 31..

Chatfield Reservoir Reallocation Study: The study contractors have fallen behind on the
studies performance contract tasks. However much ~rogress has been made on perfonnance
