In-stream Flow Decision Support System (lSFDSS)

. Discussion

The Colorado Decision Support System (CDSS) is a multi-faceted project relying on existing GIS capabilities
and products; the refinement of existing databases and development of new databases; development of modeling tools;
and integration with the department imaging system. A vital component of CDSS is the inclusion of the instream flow
databases into CDSS and refinement of existing DSS tools to access these new databases. ill addition the development of
new tools to help with ISF modeling and analysis is critical to the mission of the Stream and Lake Protection Program.

In 2001, a study was conducted to develop a comprehensive scope of work and the necessary planning tools to
determine how to incorporate ISF databases, analysis tools and modeling needs into the existing CDSS. A pilot project
for an Instream Flow Decision Support System (ISFDSS) component of the larger CDSS was developed out of this effort
and presented to the Board at its July 2002 meeting. At that time, staff indicated that a request for funding would be
presented to the Board in order to implement the project. Staff now has a cost estimate of $440,000 in order to move
forward and fully implement the ISF DSS project. The ultimate goal of this project is to produce planning, management
and modeling DSS based tools, which will provide accurate information to the Board, its staff, stakeholders, and the
general public and be part of the existing CDSS.

Specific work products that will be produced as a result of the ISFDSS project include the following:

.

A. Develop Access/ Sequel Server / Hydrobase compatible databases for:
1) New and existing Instream Flow Appropriations and Acquisitions;
2) Natural Lake Levels;
3) Court Filings;
4) Recreational In-Channel Diversions;
5) De minimis Impacts;
6) Integration and refinement of the Imaging database into the ISF DSS.
