The Technical Update and its related insights and tools build on a nearly 15-year legacy of CWCB water supply planning initiatives that began with the first SWSI in 2004. The study leverages a 27-year investment in statewide water modeling efforts, which began in 1992. This Technical Update provides a significant improvement in the scope, science, and approach to water supply planning (in SWSI I, SWSI II, and SWSI 2010), and positions Colorado for a streamlined and robust evaluation of future water needs.
- Provide a consistent statewide framework for examining future water supply and demand under different scenarios.
- Provide tools and data for Basin Roundtables to update their Basin Implementation Plans and develop detailed local solutions to supply and demand gaps.
The July 2019 CWCB Board and Interbasin Compact Committee joint meeting marked the preliminary release of the Techincal Update. The final report was presented to the Board in September 2019. The full July presentation is available on the CWCB YouTube channel.
