The Wyoming Water Development Commission's statewide planning process is to provide decision-makers with current, defensible data to allow them to manage water resources for the benefit of all the state's citizens. To support this goal, spreadsheet models were developed under the original 2001 Green River Basin Plan to determine average monthly streamflow in the basin during normal, wet, and dry years. The purpose of these models was to validate existing basin uses, assist in determining timing and location of water available for future development, and help to assess impacts of future water supply alternatives.
The spreadsheet models comprise twelve Excel workbooks, one for each of three hydrologic conditions and four distinct sub-basins:
Please Read the Surface Water Data Synthesis & Spreadsheet Model Development technical memorandum for instructions on using the model.

In addition to the spreadsheet models created for the basin, a State Mod water availability model (http://cdss.state.co.us/software/Pages/StateMod.aspx) was also created.
