• Board Meeting Date: 7/11/2007
• Description: CWCB Director's Report
• Board Meetings - Doc Type: Memo

The IECC and DNR Executive Director Harris Sherman asked us to proceed with the
goal of producing a revised draft by July 13, obtain comments from the IECC by July 23,
and then produce a revised draft for the August 6 IECC meeting.

This schedule presents difficulty getting input from the Board since the scope is
currently under internal development. Staff would like to provide the scope to the
Board but given the timing the scope will come as a red flag item.

The study was authorized by Senate Bill 07-122. The language from the Bill is provided
below:

SECTION 15. Colorado water needs and alternatives analysis - appropriation. (1) In
addition to any other appropriation, there is hereby appropriated, out of any moneys in
the Colorado water conservation board construction fund not otherwise appropriated,
to the department of natural resources, for allocation to the Colorado water
conservation board, for the fiscal year beginning July I, 2007, the sum of five hundred
thousand dollars ($500,000), or so much thereof as may be necessary, for the board to
evaluate water availability in the Colorado river basin and its tributaries. The board
shall work in full consultation with, and with the active involvement of, the basin
roundtables. The study shall consider current and potential future in-basin
consumptive and non-consumptive needs. The board, in consultation with the basin
roundtables, shall recommend whether additional study or phases of study should be
undertaken.

(2) The moneys appropriated in subsection (1) of this section shall
remain available for the designated purposes until the project is completed.

Colorado River Water Use: As of June 1,2007, storage in the four major Upper
Basin reservoirs increased by 1,019,730 acre-feet and storage in the Lower Basin
reservoirs decreased by 451,300 acre-feet during May 2007. Total system active storage
as of June 6 was 33.746 million acre-feet (MAF), or 57 percent of capacity, which is 1.095
MAF less than one year ago. (Upper Basin reservoirs increased by 0.338 MAF, and Lower
Basin reservoirs decreased by 1.433 MAP.)

The end-of-year measure for 2005 California agricultural consumptive use of Colorado
River water under the first three priorities and the sixth priority of the 1931 California
