Research on the International Boundary and Water Commission, United States and Mexico was facilitated by grants from the University of Arizona Graduate Student Development Fund that enabled the author to interview Commission officials in El Paso, Texas. He also benefitted from a graduate summer internship with the Latin American Program of the Woodrow Wilson International Center for Scholars at the Smithsonian Institution, Washington, D.C. that provided the opportunity to inter- view officials at the Department of State and avail himself of the wealth of resources in the Washington, D.C. area, especially the National Archives and Library of Congress.

The study shows that waterpolicy making in the United States takes a distributive form while policy making in Mexico resembles a mobili- zation style of policy formation. It is argued that these dissimilar national water policy systems affect the way both nations engage the other in bilateral water disputes and are relvant to ascertaining the prospects for resolving the groundwater controversy. The study surveys the relevant hydrological, historical and economic context bearing on the groundwater dispute, then examines the mole.s of domestic policy making in each country. It follows with an analysis of how national differences ir policy making are witnessed in previous bilateral water conflicts. Water policy patterns pertaining to the United States and Mexico respectively strongly influence the making of foreing policy in this sogere. Domestic policy making affects the manner of politization, objectives sought by each nation, and the diplomatic style seen in the adjustment of bilateral water agreements. Patterns seen in previous water conflicts, it is suggested, may obtain in the groundwater case. Nevertheless, the groundwater controversy is substantially different from earlier surface water disputs. Hydrological variation between problem situations is apt to fragment political interests in the ix United States. Nor is there a firm basis for approaching a settlement in international law. These conditions frustrate extrapolation of past political
