the State Engineer's Office pursuant to Section 25-8-104 (2)(d), CRS The staffs at the CWCB and.SEO are
currently cooperating with the Attorney General's Office to prepare a response for this consultation. We
expect to have a response letter ready before the end of this month and will also send each CWCB member a
copy of that letter.

Town of Otis Flood Studies: Since July 2001, the Flood Protection staff has been responding to concerns on
the part of two citizens in the Town of Otis (northeastern Colorado, approximately 35 miles east of Brush, in
the Republican River Basin), regarding the floodplain delineation for the Southwest Drainage in Otis.
Detailed field visits and field surveys have identified some shortcomings in the original 1986 flood
hydrology. A hydrology report is being finalized by CWCB staff that substantially reduces the original
flows. The revised values will be presented to the town prior to the development (with funding shared by the
town and the CWCB) of a floodplain study for the Southwest Drainage. The study will provide detailed
flood elevation and floodplain boundary information, along with a reconnaissance analysis of potential flood
hazard mitigation alternatives for the southern portion of Otis that is affected by flooding from the Southwest
Drainage.

Chatfield Reservoir Reallocation Study: CWCB staff met on Oct. 11 with Denver Water, Central Water
Conservancy District, Centennial Water Users Association, to address water users needs and concerns for the
Chatfield Reservoir "Storage Use Patterns investigation" project. The Chatfield Study Group met on Oct. 17
with State Parks representatives regarding recreational aspects of the study. This investigation is a subtask of
the major tasks for the Chatfield Study and is geared at clearing the water rights picture for water users with
interest in the reservoir space, The objective of this subtask is to develop water availability, use patterns, and
reservoir operations for four different reservoir space allocations 2900 AF, 4,500 AF, 7,700 AF and 20,600
AF. A Request for Qualifications for the storage use patterns investigation was issued by the Department of
Natural Resources State Purchasing to accept RFQs from qualified consultants. The Storage use patterns
investigation will take a few months to complete so the next Chatfield meeting will be in February 2001.

The Chatfield Reservoir Reallocation Study has spurred enough interest that the CWCB is a building and
housing a web site within the CWCB web site to provide information to interested parties. The web site is
still under construction but will have: meeting minutes, a timeline, published reports, graphics and maps for
the Reallocation Project.

Cherry Creek PMP Study: CWCB and its contractor Applied Weather Associates are moving along with
the project. The National Weather Service took 90 days to respond to a request for information so the Study
end date has been pushed back to March 2002. On Oct. 11 Mike White, Executive Assistant of the Northwest
Division of the USACE met with CWCB staff to better understand project objectives and help facilitate a
better relationship with the National Weather Service, Corps and the State, that works jointly to resolve
issues surrounding Cherry Creek Reservoir. The Corps offered full cooperation in routing the PMF and
review ofthe state's study once completed. As a result of this meeting on Oct. 21 a letter was sent to
Geoffrey Bonnin the Chief of Hydrology for the NWS in Silver Spring, MD urging the NWS to participate in
the study. The next scheduled meeting was Nov. 2 and the contractor hopes to have an interim report for the
t,echnical review panel to critique by that meeting.

Golden, Case No. 1-98CW448: In October, the transcriber for the Water Court for Water Division No.1
requested an extension of time, up to and including Nov. 28 to file the Record with the Colorado Supreme
Court. The Supreme Court granted this request. Ifno future extensions of time are granted, the CWCB's
briefs will be due in January 2002.
