  • 3. &nbsp;
  • 4. Project Background – The Klamath River
  • 5. Overarching Research Agenda <ul><li>Preliminary Assessment </li></ul><ul><ul><li>Identify the likely costs and benefits of dam removal </li></ul></ul><ul><li>Inundated Lands </li></ul><ul><ul><li>Conduct scenario building around likely use options for the reclaimed lands and estimate the associated economic value </li></ul></ul><ul><li>Property Values </li></ul><ul><ul><li>Estimate the economic value of varying levels of lake adjacency for residential properties in the study area </li></ul></ul>
  • 6. Research Project I: Objectives <ul><li>The overarching research objectives were to: </li></ul><ul><li>Identify and, if possible, quantify both the market and non-market values associated with removal of 4 dams on the Klamath River (i.e. J.C. Boyle, Copco 1, Copco 2 and Iron Gate) </li></ul><ul><li>Assess the economic impact dam removal would have on Siskiyou County </li></ul><ul><li>Perform a comparative analysis that examines the costs and benefits of dam removal </li></ul>
  • 7. Research Project I: Methods <ul><li>Identification of likely impacts </li></ul><ul><ul><li>To existing benefits </li></ul></ul><ul><ul><li>Created by dam removal </li></ul></ul><ul><li>Review of existing research </li></ul><ul><li>Scenario building </li></ul><ul><ul><li>Secondary Data Sources </li></ul></ul><ul><ul><li>Input-Output Analysis </li></ul></ul><ul><ul><li>Benefit Transfer </li></ul></ul>Credit: American Rivers

  • 9. Research Project I: Likely Costs and Benefits <ul><li>Negative – Property owners – Loss of lake view, uncertainty of inundated lands </li></ul><ul><li>Neutral/Positive – Inundated lands use </li></ul><ul><li>Negative – Loss of property taxes if property values decline </li></ul><ul><li>Neutral/Positive – Inundated lands </li></ul>Property Values <ul><li>Positive – Commercial fishers, Processing plants, Recreational fishers, Local tribes </li></ul><ul><li>Positive </li></ul>Fishing Industry <ul><li>Unknown </li></ul><ul><li>Positive – Spending from removal, tourism </li></ul><ul><li>Negative – Loss of jobs and taxes </li></ul>Local Economy <ul><li>Positive – Fisheries, Visitors, Conservationists, Fish </li></ul><ul><li>Positive – Likely increases in sport fishing industry </li></ul>Fish Populations <ul><li>Positive – Local Tribes </li></ul><ul><li>Positive </li></ul>Cultural Values <ul><li>Unknown – Cost of new source </li></ul><ul><li>Negative – If electrical rates increase </li></ul><ul><li>Neutral – Not responsible for finding alternative power source </li></ul>Power <ul><li>Negative – Whoever pays cost </li></ul><ul><li>Positive – Jobs and Spending </li></ul>Dam Deconstruction Other Stakeholders Siskiyou County Impact
