Acknowledgments

The Wyoming Statewide Water Resources Data Inventory was funded by the Wyoming Water Development Commission (WWDC) as part of a feasibility study analyzing potential approaches for updating the State of Wyoming's 1973 Framework Water Plan. The Inventory was conducted as a joint effort of the Water Resources Data System (WRDS) and Geographic Information Systems (GIS) units of the Wyoming Water Resources Center (WWRC), in coordination with the WWRC's Water Planning staff.

Results of the Inventory are contained in a series of 13 individual reports detailing the content and extent of primary sources of pertinent spatial water- and related land-resource data for each of the major river basins in the State. The basin reports are accompanied by two additional volumes, including an overview of major socioeconomic data sources important to water planning in Wyoming, and an 'agency/product' compilation which indexes by source all data products described in the basin reports.

The authors wish to acknowledge the cooperative efforts of the numerous agencies which contributed to this cataloging effort by providing critical information on the data managed and maintained by their organizations. A special thanks is extended to Mr. Evan Green, WWDC water planning feasibility study project manager, for his constructive input throughout all aspects of this project.

Introduction

Background

At the direction of the Wyoming State Legislature, the Wyoming Water Development Commission and the Wyoming State Engineer's Office in 1997 initiated a feasibility study addressing the need to update Wyoming's 1973 Framework Water Plan. The goal of the feasibility study is to determine the resources and technologic requirements necessary to develop and implement a comprehensive, statewide water planning process. Phase I of the feasibility study is centered on "issue identification" by water resource professionals and the general public via a detailed mail questionnaire and a series of public outreach events with a wide range of interest groups. The goal of Phase I is to identify the scope and range of issues to be addressed by a comprehensive water planning effort, and to determine how these issues will contribute to goal setting within the process. Phase II will identify and evaluate alternative approaches to statewide water planning, assessing each method in terms of its potential for addressing issues and goals, technology employed, resources required, and the feasibility for successful implementation.

Scope of Work

The purpose in conducting a statewide water resources data inventory was to develop an accurate and up-to-date summary overview of primary data sources and products identified as providing the necessary foundation of information required in a statewide water planning effort. The goal of the inventory was that the resulting product be utilized in identifying, analyzing and evaluating alternative methods for implementing such a planning process. Given the universal need in any resource planning activity for key, baseline categories of data, such a product will not only complement and assist in determining goals and objectives, but will also provide valuable information needed to allow planners and consultants to 'hit the ground running' in evaluating planning alternatives and implementation strategies.

The inventory focused on, but was not limited to, available digital spatial data. Both point-attribute data sets and geographic information system layers were inventoried. Emphasis was placed on cataloging natural resource data themes, but socioeconomic data was also addressed. Completion of the inventory involved four major tasks: 1) Scoping of inventory content; 2) Identifying primary data sources; 3) Determining data status; and 4) Summarizing and assessing inventory results. The first task involved developing the scope of the data inventory, in terms of data themes or categories to be addressed (e.g., surface water quantity, climate, land use, human population, etc.). The second task involved identification of all primary sources for each data category. The third task was to characterize the content, level of detail, completeness, and 'currentness' of each source. Finally, the inventory assessed the available data source options and their advantages/limitations within each thematic category.

Summary of Results

The inventory results are organized by major river basin, as defined by the U.S. Geological Survey's Level 4 Hydrologic Unit Code boundary delineations. Eleven major themes and 23 sub-themes were identified; data sets were also categorized by type as either point attribute data or GIS data. While the geographic extent of many of the data sets crossed multiple basins, each theme and sub-theme product has been addressed in each of the individual basin compilations. An individual compilation was developed which addressed major sources of socioeconomic at the state and federal government level. Finally, the inventory also includes an "agency/product index" categorizing available data by source across all basin boundaries.

How This Document is Organized

The results of the data inventory are contained in a series of comprehensive, stand-alone documents designed principally for World Wide Web Internet publication, with limited hardcopy availability. Thirteen basin compilations have been produced, each containing sections on basin geography, interstate stream issues (if applicable), and individual data sheets for each data source indexed by theme and sub-theme. Separate documents follow on 'major socioeconomic data sources' and an 'agency/product' index.

In each basin document, data products are organized under 11 major themes. Major themes are separated by dividers and may include up to six sub-themes each. The following page contains a listing of the theme/sub-theme organization of this document.

It should be noted that, while every attempt has been made to identify and characterize all major sources of available, water resources data for the State, the comprehensiveness of the inventory has been largely defined by participating agency input. Further, the data documentation provided in the inventory reports is recommended solely as a general overview of available data products; questions or concerns regarding specific use of data products should be directed to the primary source identified for each data sheet.

Data Inventory availability and Maintenance

Given the size of the Inventory's content, the resulting data catalogs have been designed for primary distribution on the Internet's World Wide Web, specifically through access of the WWDC's water planning homepage (http://waterplan.state.wy.us/).

The thirteen basin data catalogs, socioeconomic data sources, and the agency/product index reflect the results of an intensely focused, five-month effort to comprehensively inventory major sources of water resource data and related information for the State of Wyoming. While it is recognized that any inventory becomes outdated immediately upon completion, it is hoped that through continued agency support, the original inventory will be periodically updated and maintained in a World Wide Web Internet environment throughout ongoing and future state water planning efforts.
