PDF (113.3mb) Access the 2010 Wind/Bighorn River Basin Update Final Report here
PDF (674kb) Table of Contents for the 2010 Wind/Bighorn Basin Plan Update
PDF (136kb) The Wind-Bighorn Basin Plan Update (Basin Plan Update) provides an update to the previous 2003 Wind-Bighorn Basin Plan (previous Basin Plan).
PDF (383kb) Description of an Interactive Presentation Tool developed for the 2010 Wind/Bighorn basn plan update
PDF (2,062kb) This chapter describes the general physical, socioeconomic, legal and institutional setting for the Wind-Bighorn Basin.
PDF (1,756kb) This chapter presents the physical characteristics (quantity and quality) of surface water in the Wind-Bighorn Basin.
PDF (5,225kb) This chapter describes current water uses in the Basin. Water use includes both consumptive and non-consumptive uses. Consumptive uses are generally agricultural, stock water, municipal/domestic, industrial/mining water, and reservoir evaporation, while recreational and environmental uses are generally considered non-consumptive uses.
PDF (290kb) This report updates the original Wind-Bighorn River Water Basin Plan water demand projections. The water use projections were developed for agricultural, industrial, municipal, recreational and environmental water use in the Basin. Projections for years 2020, 2040 and 2060 are provided.
PDF (2,178kb) Water availability is the amount of water that is physically and legally available for new water uses in the Basin. Water availability was determined for surface water uses using a spreadsheet model.
PDF (219kb) Project opportunities and program strategies have been developed as part of the Basin Plan Update in an attempt to address existing and future water use issues in the Wind-Bighorn Basin (Basin) as developed by the Basin Advisory Group (BAG) and the basin planning team.
PDF (113kb) This chapter describes the process for developing strategies and the final list of opportunities. More information on program strategies is contained in Technical Memorandum 6.
PDF (126kb) The scope of the Wind-Bighorn Basin Plan update is to document current and future water uses within the Basin, adjust estimates of water availability based on recent hydrologic information, including the 2000.s drought conditions within the basin.

The spreadsheet models developed for the previous Wind-Bighorn Basin Plan were used for the Basin Plan Update. These spreadsheet models were documented in Technical Memorandum 3B/3C Spreadsheet Model Development and Calibration (MWH 2003) of the previous Basin Plan. Except for updates to input data sets (documented in other technical memoranda as part of the Basin Plan Update) and the changes documented within the text of this memorandum, the spreadsheet models remain mostly unchanged from the previous Basin Plan.
The most extensive modification to the spreadsheet models is the development of a hydrologic database that is incorporated directly into the spreadsheet model by being dynamically queried to populate the spreadsheet model input datasets. Previous versions of the spreadsheet model incorporated "cut-and-paste" methods from separate spreadsheet data sources to populate the spreadsheet models. The updated methods provide a much quicker and more reliable method for populating the spreadsheet models, and maintain a historical documentation of calculation methods. The database was configured to allow migration to other basin plans.
Please Read Task 4B - Spreadsheet Model and Hydrologial Database for instructions on using the model.
