ABSTRACT
The International Joint Commission (IJC) General Principles reflect two elements critical in determining the benefits and defining the equitable division of gains in the international development of a river basin system. The first concerns the economic or efficiency aspect of a river basin design and/or development in which both parties have an interest provided that the resulting division of the gains is to be equitable. The second element of the IJC General Principles relates to the matter of assurance that party to the co-operative venture will be penalized by pursuing a course of action that maximizes the net gain of the parties combined. In contemplating a co-operative development with which to compare results, Crippen Wright Engineering made the assumption that US interest in the construction of Libby would have to be indulged. A plan which developed storage with the view of supplementing existing US storage would require developments compatible with the Libby storage project.
