– These web-based tools can be used without additional software so that users can easily access all the CDSS’s water data.
– Specific software products used to develop the CDSS in various basins are available for users to download for either creating new models or using baseline data sets (Modeling Data).
– Baseline data sets developed through the CDSS are available for various Software Products.
– Geographic Information Systems (GIS) data developed through the CDSS are available for download for each of the divisions throughout Colorado.
– Various documents related to the CDSS are also available so that users can view or download the latest reports, technical memoranda, publications, meeting materials, and more.
