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 Green River Basin. 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 structure of this final report is to present findings in enough detail to explain the
overall plan without deluging the reader in technical minutiae. Technical memoranda have
been prepared which delve into the many individual topics in detail, and it is to these
documents the reader should turn for answers to questions about details, methods, and for
selected references. No separate list of citations is provided herein other than for the
Technical Memoranda (which, individually, contain complete bibliographies).
