Introduction
The Board entered into a Feasibility Cost-Sharing Agreement (FCSA) with the Corps of Engineers, Omaha
District in 1999 for the perfonnance of a Storage Reallocation Study for Chatfield Reservoir, Littleton, Colorado.
The purpose of the study is to detennine the feasibility of additional water supply storage in the existing reservoir.

The Corps of Engineers in cooperation with the CWCB and the Chatfield Work Group formulated a Scope of Work
that addresses all the Corps' study requirements for a reallocation study and the Colorado Chatfield Reservoir users
concerns.

e

On January 2000, the Corps in cooperation the CWCB gave a "Notice to Proceed" to Simon and Associates - the
Selected General Contractor - to proceed with the study. The study "Scope of Work" has seventy two performance
tasks.

Study Progress Report

The general contract: The study has encountered a number of General Contractor problems during the
perfonnance of study tasks. Currently, the Corps is performing a number of study tasks in-house. This change in
the administration has resulted in a substantial study products delay. The Corps has elected to perform the
reservoir routing study in-house. The general contract is in-progress to be amended with the same completion
performance schedule.

Contracts by Others: The general contract and the "Scope of Work" requires that two major study tasks be
accomplished by the sponsor (CWCB). These two tasks requirements are: A Storage Use Patterns Analysis and A
Recreation Master Plan.

The CWCB has contracted the professional services of Brown and Caldwell to perform the Storage Use Patterns
Analysis. The Board has received a draft report dated September 2002. The fmdings in the report are under
review by staff. I will make a brief presentation to the Board and present the preliminary study fmdings.

The CWCB and Colorado State Parks staffs are working jointly to prepare a " Scope of Work" that will evaluate
the impacts of an increased storage in the existing conservation pool. I will make a brief presentation of the study
objectives and study product.
