Analysis and Technical Update

In 2016, the CWCB launched an update and upgrade of the state’s supply and demand projection data and tools underpinning Colorado’s Water Plan. The process has come to be known as the Analysis and Technical Update to Colorado’s Water Plan (or simply, Technical Update, formerly "SWSI"). This statewide supply study serves two primary purposes to: (1) provide a consistent statewide framework for examining future water supply and demand under different scenarios and (2) 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 IBCC joint meeting marked the preliminary release of the Technical Update. The final report was presented to the Board September 2019. The full July presentation was recorded and remains available for viewing on the CWCB YouTube channel.

The 2019 Technical Update replaces the document known as the Statewide Water Supply Initiative 2010 (SWSI). The archived SWSI 2010 can be accessed for reference on the CWCB FTP site during the website transition.
