Abstract Several reports related to dams and dam removal have been released this
decade by non-governmental organizations including Dam Removal: Science and
Decision Making by The Heinz Center which focused on small dams, since most
of the dams removed to date as well as those likely to be removed in the near
future fall into this category. The report found that there is a need for case study
social research on small dam removal. Accordingly, this thesis seeks to identify
the social and policy factors that influenced the decision to remove Chiloquin
Dam on the Sprague River, Oregon. This irrigation diversion dam was
constructed from 1914-1918 for the Klamath Tribes under the federal Indian
Irrigation Service program and subsequently transferred to the Modoc Point
Irrigation District in 1973, after termination of the Tribes by the federal
Government. Chiloquin Dam was identified in a 1988 Endangered Species Act
listing as a primary factor in Lost River and shortnose sucker species decline, a
species of cultural significance for the Klamath Tribes. Although early reports,
including those by Klamath Project irrigators, called for improved fish passage at
Chiloquin Dam, it was not until jeopardy biological opinions triggered a shut off
of water to the federal irrigation project in 2001, that Chiloquin Dam became a
priority. Directed by legislation, the United States Bureau of Reclamation
convened stakeholders in the Chiloquin Dam Fish Passage Study for nine months
in 2002-2003 to determine a preferred alternative for fish passage, of which dam
removal was recommended.

To identify the social and policy factors that influenced the Chiloquin
Dam removal decision, 21 informants were interviewed including participants in
the Fish Passage Study as well as those involved in the 1988 Endangered Species
Act (ESA) listing. Among the findings, respondents perceived that the ESA was
the driving policy force, along with tribal restoration (the tribal trust
responsibility) in the dam removal decision. Modoc Point Irrigation District
members (Off-project) and tribal respondents believe that the dam removal was
motivated by political support for Klamath Project irrigators. Despite these beliefs
and divergent expectations for Chiloquin Dam fish passage, with the political
imperative and resources, an agreement was reached in which each party had their
needs addressed.
An analysis using the social construction model found that the events of
2001 threatened to push irrigation interests from a powerful advantaged political
position. The Fish Passage Study presented capacity and inducement instruments
that responded to irrigation and tribal concerns and may also serve to restore the
irrigation position as an advantaged social construction. Overall, uncertain
science, differing beliefs of what dam removal would mean, and a lack of political
priority served to delay action on fish passage at Chiloquin Dam from the ESA
listing in 1988.
