Book excerpt: Much has been written about legal questions surrounding Indian water rights; this book now places them in the political framework that also includes water development. McCool analyzes the two conflicting doctrines relating to water use—one based on federal case law governing the rights of Indians on reservations, the other sanctioned by legislation and applied to non-Indians—based on the "iron triangles" of bureaucrats, legislators, and interest groups that dominate policy issues. He examines the way federal and BIA water development programs have reacted to conflict, competition, and opportunity from the turn of the century to the 1980s and updates the situation in an introduction written for this edition.
