D E S T I N AT I O N DAM REMOVAL designing historical narratives into post-industrial landscapes Carolyn Corl 1 Approval Project Chair: Mark R. Eischeid Committee: Chris Enright Committee: Kory Russell Submitted in partial fullfillment of the Master of Landscape Architecture Department of Landscape Architecture College of Design University of Oregon June 11, 2021 ii iii In recent decades, dam removals on American rivers have accelerated due to environmental concerns for stream ecology coinciding with the obsolescence of dam infrastructure built in the early 20th century. In some cases, parts of a dam’s structure are left behind to minimize Abstract riverbank disturbance or to appease community members who oppose dam removal for its cultural significance. Like other post-industrial landscapes, the traces and ruins associated with dam infrastructure tell a story of the site before, during and after the infrastructure severely altered the landscape. At dam removal sites specifically, acknowledging this narrative of landscape change and recovery is a unique design opportunity that cannot be addressed through restoration or preservation alone. But through literature review and case study analyses, this project builds a design framework for engaging with the traces left behind by dam removal. By examining how landscape architects have previously worked with other types of post-industrial landscape remnants to elicit a site’s narrative through design, a decision-making procedure for proposing design interventions for historic remnants and how to make them compatible with an overall design concept was developed. The design intervention framework is then exemplified through a proposed site design at the former Savage Rapids Dam on the Rogue River in Southern Oregon. iv v I would like to thank the University of Oregon faculty I also want to acknowledge that the site for this for showing me how to understand landscapes through project is located on the ancestral homelands of the design. I am especially grateful to my project chair, Mark Takelma people who lived in the Rogue River Valley for Eischeid, who thoughtfully and enthusiastically guided millennia.

Thank you all for your feedback and encouragement throughout this project. Thank you to my colleagues at the Cultural Landscape Research Group. Working with you all has been a highlight of my time at graduate school and your support during the past year has been so meaningful. To my family and friends, thank you for your support and love.

The objective of this project is to create a narrative-driven design framework As many types of twentieth century infrastructure for providing visitor access at historic dam removal sites continue to deteriorate, we will be left with landscapes that enhances recreation with place-making. scattered with industrial ruins. This dilemma continues to While dam removal is a national issue, this project is CHAPTER 1: be addressed by landscape architects, who use design focused on dam removals that have occurred along the to reframe outdated post-industrial infrastructure as Rogue River in Southern Oregon (Figure 1.1) The Rogue cultural and recreational resources for public access. In has long been famous for its plentiful Coho salmon Introduction recent years, one type of infrastructure that continues to runs and several dam removals in recent decades have become obsolete is the dam.

Since 2012, more dam removals that occurred along a twenty-mile stretch than 1,200 dams have been removed in the United States, of the Middle Rogue River (Figure 1.2). The three dams with 99 dams removed in 2018 alone (American Rivers, were each installed for diff erent purposes at diff erent 2020). As dams are removed, their ruins often remain times, but all were centered around the Euro-American in the landscape to minimize disturbance on riverbanks colonial settling and farming of the Rogue River Basin in because they are so structurally embedded into the river’s the late 19th century and the early 20th century.

The by visiting these dam removal sites, making them popular fi rst dam to be removed was the Gold Hill Dam in 2008, a destinations for environmental enthusiasts. Sometimes diversion dam used by the town of Gold Hill for water and dam remnants are also often left behind in the landscape energy and built in the 1940’s. Next to be removed was to give community members a piece of history to hold Savage Rapids Dam in 2009, which was an irrigation dam on to (Weir, 2021), which also attracts people who are built to serve surrounding farmland in 1922.
