Green River Basin Water Plan
2010 Spreadsheet Models

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:

• Upper Green River Basin from the Green River headwaters to Flaming Gorge
• Blacks Fork River Basin from the Blacks Fork and Smiths Fork headwaters to Flaming Gorge
• Henrys Fork River Basin from the Henrys Fork headwaters to Flaming Gorge, and
• Little Snake River Basin from the Little Snake headwaters to the USGS stream gaging station Little Snake River near Lily, CO.

Please Read the Surface Water Data Synthesis & Spreadsheet Model Development technical memoradum for instructions on using the model.
