As authorized by the Wyoming Water Development Commission in its contract scope of work, this planning document presents current and proposed (estimated) future uses of water in Wyoming's Northeast River Basins. Uses to be inventoried include agricultural, municipal, industrial, environmental, and recreation. Both surface and ground water uses, as well as overall water quality are described. Given current uses, the availability of surface and ground water to meet future requirements is estimated. To lay the groundwork for future water development, a review of the current institutional and legal framework facing such projects is presented. Finally, thoughts are given to guide implementation of the water planning process.
The intent of this summary report is to describe the planning study in sufficient detail for the reader to gain a general understanding of the investigations that were performed and the results of those investigations. For detailed information on a specific topic the reader is directed to the technical memorandum prepared for that topic. References used in preparing the technical memoranda are not repeated in this summary report. These references are presented in the individiual technical memoranda.

PDF (10,458kb) or HTML This chapter describes and quantifies the current water uses in the Northeast Wyoming River Basins planning area. The quantification of current water consumption is used to evaluate the overall use of water in the Basin relative to Compact allotments, for comparing existing water use to existing water supplies, and as a basis for projecting future water demands by the various uses.
PDF (259kb) or HTML For assessing the need for water into the future, this plan has developed estimates of water demand for each major use category out to year 2030. These estimates are discussed in detail in technical memoranda for each topic.
PDF (1,469kb) or HTML This chapter identifies future water use opportunities that can be implemented to satisfy the water demands in the Little Missouri River, Belle Fourche River, Cheyenne River, and Niobrara River Basins in Wyoming. The list of opportunities presented in this report is intended to be used by individuals and organizations that need to develop a water supply to satisfy their specific needs.

There are sixteen spreadsheet workbooks, one for each of three hydrologic conditions(wet, normal, dry) and one master for each of the four distinct areas:
For further information including both a user's guide and engineering documentation of the models please refer to the Spreadsheet Model Development and Calibration.
Steps for Downloading the Models
The three workbooks (wet, dry and normal years) for each area are yoked together with a simple menu-driven graphical user interface (GUI), effectively creating four area models. In addition, the spreadsheet models are stored as zipped Microsoft Excel files using WinZip compression software. An evaluation version of WinZip may be downloaded at http://www.winzip.com/download.htm

* Please note that these files are in read only format. Any changes to the models made by the user may change the results and must be saved with a new file name.
** For Windows XP users - Due to additional security levels, XP users may have to manually change their security levels. If you receive a message when opening Microsoft Excel that reads as follows: "Macros in this workbook are disabled because the security level is high..." click OK and perform the following routine: Under the Tools menu, click on Macro then Security. Change the Security Level to Medium, this will enable the user to go to the Spreadsheet Model Main Menu.
