through cloud masses. In addition, methods of instrumentation that are used to provide input to
real-time decisions and evaluate results are discussed. Finally, this manual outlines the steps that
must be taken to implement a cloud seeding project. A glossary ofterms is appended. To order or

. WMA Response to NRC Report (Attachment): Its tough sledding in the weather modification
world as verification of results has been a multi-decadal battle. The CWCB sits on the North
American Interstate Weather Modification Council comprised of states with weather modification
programs and discussions are always as follows: "We have a mountain of evidence that cloud
seeding works and no concrete proof. What constitutes concrete proof." The following attachment
frames the dilemma in weather modification and the differences between operational and research
programs and the need for cooperation.

Arkansas River Basin

Senator Salazar Offers PSOP Proposal: In February, U.S. Senator Ken Salazar announced that his
support of the Preferred Storage Option Plan (PSOP) is conditioned upon the ability of all parties to reach
an agreement that addresses the environmental and economic impacts of water transfers on downstream
communities. The text of his message is attached.

Arkansas Valley Conduit: Participating entities continue to refine flow estimates for final pipeline sizing
and also to analyze water treatment options to resolve questions about whether the conduit should
transport treated or raw water. The Pueblo Board of Water Works has suggested a possible route that
would utilize a portion of the City's distribution system, and provide treated water on a regional basis.
The USBR, the agency originally authorized to construct the pipeline, has completed its own evaluation
ofthe project and will be submitting those findings directly to Congress.

Arkansas River Compact Administration: There has been little progress on efforts to seek advise from
participating federal agencies on the respective state positions on disputed reservoir accounting issues or a
potential study of transit losses between John Martin Reservoir and the Stateline.

Kansas v Colorado: Litigation Account Activities: The Board is funding a number of activities related
to the ongoing litigation with Kansas over the Arkansas River Compact from the Litigation Account of
the Construction Fund. Weare now under way on the following activities:

Completed first year of three year study of irrigation monitoring with Colorado State University (CSU),
and began purchasing equipment for weather station enhancements. The initial status report on the
irrigation activity was made on Feb. 23 to state officials and attorneys and based on feedback the CSU
research team has finalized plans for the 2005 irrigation season.

Engineering consultants have begun to review modifications to the HI Model and to prepare to potentially
serve as expert witnesses in the concluding phase of the case.

Developed a plan to have CSU build the first of two Iysimeters at its Rocky Ford Research Farm. Outside
peer review of the preliminary design drawings and plan is completed and the results are being
incorporated into a final construction plan and cost estimates. A CSU technician, being partially funded
through this project participated in the recent construction of a new Iysimeter by Texas A&M Univ. Staff
from A&M are acting as DWR's design consultants.

To date the CWCB has paid about $90,000 of the $750,000 authorized for these projects.

We are seeking guidance from the AG on making the first requisite annual report to the General
Assembly on the use of the litigation account.
