Water experts are an integral part of the institutional capacity affecting change in governing water resources.  County agencies and citizen-based groups rely on the assessments by experts for ground water development and protection programs. County agencies and citizen-based groups often times retain additional experts to conduct “peer reviews” of the reviews and studies prepared by hydrogeologic experts on behalf of their clients.  Incompatibilities often arise over the use and equitable, or inequitable, distribution of ground water, “values” attached to ground water, conceptual models, uncertainty, as well as on missing information, inaccurate data, and how the “science” will be used by the different experts, fueling the “dueling expert” syndrome.   Compounding these incompatibilities are “hydromyths” that exist among water experts and ground water managers.  The traditional hydromyths include that ground water is unreliable or fragile resource, or that ground water mining is always unethical because it is unsustainable and damages future generations.  But dueling experts joust with a “hydro-hydra” of issues associated with developing and protecting ground water that are distributed within the field of hydrology.   The purpose of this presentation is to analyze this “dueling experts” situation using relevant environmental conflict resolution concepts.  The analysis in this presentation is supplemented by a discussion of the hydro-hydra that fuels conflict.  The analysis of one case study in Oregon will be used as a proxy for many case studies analyzed from across the U.S. to suggest that citizen-based groups need to focus on an approach that (1) acknowledges the different types of “science” operating within a specific situation, (2) encourages Joint Fact Finding (JFF) among stakeholders at the onset to specify the information that they desire to collect, and (3) defines process to resolve future conflicts over ground water resources, perhaps through a collaborative process facilitated by independent agencies which already exist.
