OpportunityTitle: Willow Creek Reservoir Water Quality Research and Evaluation Studies
AdditionalInformationOnEligibility: This opportunity is restricted to non-federal partners of the Pacific Northwest Cooperative Ecosystems Studies Unit (CESU).
Description: Background: The overall goal of this project is to improve water quality conditions in Willow Creek Reservoir for the benefit of the community in and surrounding Heppner, Oregon. Water quality issues that plague the lake include: dense cyanobacteria (or blue-green algae) blooms, low dissolved oxygen concentrations, and high nutrient concentrations. Blooms of cyanobacteria are known to produce toxins, thereby threatening the aquatic ecosystem and potentially exposing humans and animals to risk of death or chronic illness such as neurodegeneration and liver damage. Each summer, Willow Creek Reservoir is posted with health advisories warning users of the potential hazards associated with recreating on the lake. Furthermore, fish kills, foul odors and other nuisances are common in Willow Creek Reservoir affecting the community&#8217;s ambiance, limiting tourism and recreation on the lake. This analysis draws upon prior research, readily available data, and new research and data to develop and implement an evaluation program for the restoration of Willow Creek Reservoir and its upper basin. Research results will provide public benefit through enhanced water quality in Willow Creek Reservoir producing public recreation opportunities and natural resource benefits. Brief Description of Anticipated Work: Objective 1: Conduct biweekly monitoring of in- and outflows and a site in the reservoir to continue the long-term dataset development for Willow Creek Reservoir to support management decisions and evaluate their effectiveness if and when implemented. Objective 2: Develop a whole-lake hydrodynamic model to evaluate reservoir water quality trajectory under future management strategies. Objective 3: Re-evaluate the currently installed aeration system for efficiency, modification in operation (e.g., timing, or air vs pure oxygen) or deployment (physical location in reservoir, and specific configuration). Once evaluation of equipment is complete, efficacy of aeration system within the reservoir could lead to a long term study. Objective 4: Present research results at public and technical meetings to disseminate findings.
