ABSTRACT
The paper by Maddock and Matalas can be divided into two major sections: the first specifies water requirements imposed by various coal mining and gasification scenarios, and the second examines the adequacy of water availability to meet such requirements in the Yampa River Basin and the storage requirements for overcoming potential deficits. Their hydrologic analysis shows, for a highly simplified case, shortfalls which might be expected and the storage capacity needed to meet these deficits at a prescribed level of reliability. This discussion focuses on the second portion of their study, and in particular suggests the form and extent of the analysis that would have to be undertaken to promote their storage study from a simple didactic model to a working tool suitable for implementation by agencies or institutions interested in monitoring and managing water supply and quality. This discussion is not intended as a criticism of the analysis suggested by Maddock and Matalas because it is understood that their work is merely illustrative of the form which a complete analysis should take.
