ABSTRACTInterregional conflicts over the allocation and transfer of water supplies have occurred with increasing frequency in the contemporary United States. This paper presents the results of a case study of citizen opposition to a proposal to transfer water supplies within Oklahoma. Residents of the area adjacent to Lake Tenkiller in eastern Oklahoma were surveyed concerning their reactions to a proposal of the City of Tulsa to transfer large volumes of water from the reservoir to the city. Results of the survey indicated that a community based concern for preserving local water levels transcended individual self‐interests in maintaining Tenkiller's water levels. The results support the recently developed concept of “turf politics,” which suggests that regional and community based considerations tend to dominate interregional locational conflict resolution.
