Introduction
Progress reports on the Chatfield Reservoir Reallocation Study and a proposed "Letter of Commitment" for
signing by the interested water users were presented and accepted by the Board at its January 25, 2005 Board
meeting. At the January 2005 Board meeting, a Mount Carbon Metropolitan District (Mount Carbon) legal
representative from Ciliberto & Associates, LLC., made an appeal for water storage space in the proposed
. 20,600 acre-foot watcr supply pool.

The appeal requested that Mount Carbon receive 100 percent of their 1985 conditional water storage decree of
800 acre-foot. After presentations and some discussion, the Board asked if Mount Carbon was in a position to
accept the 100 acre-feet offer originally offered from the other water users interested in storage space. Mount
Carbon's representative said she was not and the Board denied the Mount Carbon request for 800 acre-foot of
storage space. Following the Board action, the Attorney General's Office and Mount Carbon have been
communicating regarding any storage space in the proposed Chatfield Reservoir storage pool. To date no
official response has been received from Mount Carbon.

Project Activities
The Board staff, in cooperation with the Attorney General Office, has prepared a final "Letter of Commitment"
(letter) and the letter has been mailed to the sixteen water users that received storage space in the Water Users
Subcommittee allocation process. The Board is receiving signed letter of commitment from the water users and
the Director is executing the "Letter of Commitment" upon the receipt. Staff anticipates receiving the
Feasibility Cost Share Agreement (50/50 cost share agreement between the CWCB and the Corps) planning
funds from the local water users at part of this "Letter of Commitment" by the June 30, 2005 deadline set forth
by the CWCB.

In addition, the Corps, in cooperation with DNR and the Board staff, is completing EIS scoping activities for the
commencement of further detailed recreational and environment investigations for impacts of the proposed
additional storage space in the Chatfield storage space feasibility study.
