  • Taming the Tumalo : A Damned Dam Repurposed for Recharge

    Creator:
    Harpham, Kelsey
    Abstract:
    The Tumalo Project at Tumalo Reservoir in Central Oregon was proclaimed a failure almost as soon as it was completed. As the reservoir filled with water diverted from Tumalo creek in the spring of 1915, sinkholes developed in the reservoir floor and every last drop of captured water disappeared into...

  • Overcoming the Hypolimnion: Stakeholder Influence in Transboundary Water Quality Governance

    Creator:
    Offutt, Alyssa J.
    Abstract:
    Global surface water quality has been degrading with predictions of negative trends in meeting the Sustainable Development Goal ambient water quality targets (Mead, 2019; WWAP & UN Water, 2019). These water quality impacts can cross borders and impact populations in world’s 204 transboundary lake and reservoir basins (ILEC & UNEP,...

  • A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

    Creator:
    Woody, Jen
    Abstract:
    An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...

  • Hydrogeologic field investigation and groundwater flow model of the southern Willamette Valley, Oregon

    Creator:
    Craner, Jeremy D.
    Abstract:
    Elevated groundwater nitrate (NO3 -) concentrations in the Southern Willamette Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to declare a Groundwater Management Area (GWMA) in Spring, 2004. To better understand direction of groundwater flow, groundwater age, and nitrate transport pathways of the SWV we developed a steady-state...
