-,4' . . . Water Project Construction Program - Project Data Applicant: Colorado Water Conservation Board Project Name: Instream Flow Decision Support Svstem (ISFDSS) County: Statewide Drainage Basin: Statewide Drainage Basins Project Type: Component of Colorado Decision Support System (CDSS) Water Source: N/A Total Cost: $440,000 Funding Sources: CWCB CWCB Investment: Interest Rate: N/A $440,000 Term: N/A 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. In 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 200 I, 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 the ISF DSS was developed out of this effort and presented to the Board at it July 2002 meeting. In order to fully implement the ISF DSS project, a total of $440,000 is being requested. 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. Products Produced: . A. Develop Accessl Sequel Server I Hydrobase compatible databases for: I) 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. B. Consolidate existing GIS layers and develop new GIS layers, which may include hydrography, land ownership, gages, counties, Instream Flow and Natural Lake Level water rights, etc. C. Develop Data Management Interfaces with the CDSS. D. Develop modeling tools for ISF needs assessments as they relate to New Appropriations, Acquisitions; Protection and Enforcement of 1800+ state held ISF and Natural Lake Level water rights. Tools will focus on: I) Gaging needs and a comprehensive low flow waming system; 2) Real time administration ofISF rights based on further development and refinement of existing modeling tools such as the Colorado Water Rights Administration Tool; 3) Development of other tools and Data Management Interfaces for Deminimis Impact on ISF reaches. E. A comprehensive ISF DSS, which is accessible via the WEB.
