Introduction and Background: This study is in support of the Secretarial Determination on the removal of four dams on the Klamath River and related restoration activities in the Klamath basin. The four dams are Copco I, Copco II, J.C. Boyle and Iron Gate. Lands under these reservoirs and adjacent lands associated with the hydroloelectric project and owned by PacifiCorp are to be transferred to the states of Oregon and California or an entity yet to be determined. Lands adjacent to Keno Dam presently owned by PacifiCorp are to be transferred to the Department of Interior to support the continued operation of the Keno dam and impoundment. All of these lands are described in the Klamath Hydroloelectric Settlement Agreement (KHSA) as Parcel B lands and represent approximately 8000 acres of property owned by PacifiCorp. These lands are to be managed for public interest purposes such as fish and wildlife habitat restoration, public education, and public recreational purposes as outlined in section 7.6.4 of the KHSA. Lands adjacent to Keno Impoundment are intended to support the continued operation of Keno Impoundment for the Klamath Project. Adjacent to Copco 1 Reservoir and in the vicinity of all four reservoirs are private lands, some of which have primary or secondary residences constructed on them. There are also lands administered by various state and federal agencies in the vicinity of all four dams. Drawdown of the reservoir areas is expected to alter the hydrology of the Klamath River and impact lands immediately adjacent to the reservoirs or downstream. Amongst the considerations regarding dam removal is the effect on real estate. Real estate issues are varied and fall into a number of categories for discussion. These categories include: Lands being transferred to the States, including lands currently inundated by the reservoirs Lands needed in support of the project Adjacent private lands that may be affected by the project II. Purpose: The purpose of this real estate report is to present to the Secretary the potential impacts and liabilities of an affirmative decision to remove the dams real estate including affected categories of land. III. Lands being transferred to the States: A. The KHSA stipulates that the States of California and Oregon will take ownership of certain lands of PacifiCorp, including formerly inundated lands, and manage them for the benefit of the public. The States or a designated third party approved by the signatories to the KHSA may accept ownership. While the 2 | P a g e intent of the KHSA (section 7.6.4) is that these lands would be managed for the benefit of the public, it provides an option to allow for other uses based on agreement by the settlement parties. At the date of this report, neither Oregon nor California has developed specific management plans. B. The disposition of PacifiCorp structures (houses) on lands near Iron Gate and Copco Reservoirs is unknown at this time. PacifiCorp has provided an inventory but no details about size or condition were included in the inventory. As more information becomes available the State of California will make a determination regarding their plans for the structures upon transfer to the State. IV. Lands needed in support of the project include: Temporary use of access roads for construction and staging areas: 1. Access routes identified for use during construction are on PacifiCorp lands, lands managed by BLM or within FERC project boundaries. The same is true for construction and staging areas. 2. Currently existing public roads will be used for removal of metal and other construction waste to landfill sites. All local weight and load restriction will be adhered to. No private roads have been identified for use at this time. Permanent rights to be acquired 1. Mitigation sites, spoil sites and any lands needed permanently as a result of the project are identified as being located on PacifiCorp lands, lands managed by BLM and adjacent private lands. 2. Permanent rights for lands to support the operation of Keno Dam by Reclamation for Klamath project purposes will be transferred from PacifiCorp to DOI. A description of the real estate to be transferred will be presented in a separate report to be available upon conclusion of negotiations on details of the transfer. V. Affected lands There are private lands adjacent to or within close proximity to the reservoirs. These are lands with access to or views of the reservoirs and are generally around Copco 1 and Iron Gate reservoirs. Construction of the Copco and Iron Gate dams created reservoirs behind the dams. These reservoirs are open to the general public and have been utilized for recreational purposes (fishing, boating, etc.) for many years. In turn, these recreational uses have led to light residential development of some of the privately held real estate surrounding the reservoirs. Other affected lands are lands adjacent to the river and downstream of Iron Gate Dam to the estuary for the Klamath River. The Klamath River passes through federally designated wilderness, National Forests, public land managed by the BLM, private lands, and rural tribal reservations for most of its course downstream of Iron Gate Dam. There are several unincorporated communities downstream of Iron Gate Dam such as Happy Camp, Hamburg, Seiad Valley, Gottville, Orleans, Weitchpec, Klamath, and Requa. Within a one-quarter mile buffer of the Klamath River downstream from Iron Gate Dam to the Estuary, there are approximately 40,500 acres of open space and public lands, 15,600 acres of 3 | P a g e agricultural lands, 290 acres of residential uses (of various densities), 24 acres of tribal reservation lands, 2,478 acres of urban reserve1, and 26 acres of commercial use. In addition, the entire Klamath River is designated a wild and scenic river downstream of Iron Gate. A. Case studies on effects to property values Appendix A contains a review of previously completed reports and studies on the effects to real estate of dam removal. The purpose of this literature review was to attempt to locate and review documents and studies which have examined the impacts of dam removal on private property values. By reviewing the conclusions of the previous studies it was hoped it would be possible to draw parallels with the potential impacts that removal of the four Klamath River dams could have 1 The following communities have been designated “Urban Reserve” in their county‟s General Plans to accommodate future growth: Orleans, Humboldt County at RM 48; Weitchpec, Humboldt County at RM 43; Klamath Glen, Del Norte County at RM 6; Requa, Del Norte County located 0.75 miles north of RM 1.25; Requa, Del Norte County located 0.75 miles north of Estuary (General Plans – Land Use [computer file].

As described in Battelle, 2007, Economic Support for the Elwha River Watershed: Final Economic Characterization Report with Monitoring Recommendations, “the economic costs associated with dam removal are complex and difficult to define.” These case studies point out this complexity and illustrate the challenge of forecasting impacts on property values in other

  • 10.0 Screening Level Determination of Chemical Contaminants in Fish Tissue in Selected Project Reservoirs
    10.0 SCREENING LEVEL DETERMINATION OF CHEMICAL CONTAMINANTS IN FISH TISSUE IN SELECTED PROJECT RESERVOIRS 10.1 DESCRIPTION AND PURPOSE Past activities in and around Lake Ewauna and other locations in Keno reservoir suggest that sediments in the reservoir may be contaminated with agricultural chemical residue, poly- chlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), and trace metals including mercury. While it is unknown whether the Klamath Hydroelectric Project has contributed to the potential sources of sediment contaminants, it is possible that accumulation of potentially contaminated sediments in Project reservoirs has resulted in conditions conducive to bioaccumulation of such contaminants. Both Oregon1 and California2 have water quality standards concerning bioaccumulation of toxic substances. Therefore, the water quality agencies of both states requested that studies be done to determine whether bioaccumulation of potentially toxic contaminants was occurring. The purpose of this study was to determine if edible fish in the Project reservoirs contain unaccept- ably high residues of potentially toxic contaminants. 10.2 OBJECTIVE This study is intended to be a Tier I (screening level) study of the Project reservoirs. The primary aim of the study was to identify whether certain fish species are bioaccumulating toxic substances at levels that may adversely affect public health or wildlife via fish consumption, or be harmful to aquatic life (based on existing quality criteria/guidelines for the protection of human health, wildlife, and aquatic life). Locations were sampled where fishing is practiced, including areas where various types of fishing are conducted routinely (e.g., from a pier, from shore, or from private and commercial boats), thereby exposing a significant number of people to potentially adverse health effects.

  • Exhibit E: Botanical and Wildlife Resources
    E5.0 BOTANICAL AND WILDLIFE RESOURCES This section on the terrestrial resources (plants and wildlife) associated with the Klamath Hydroelectric Project (Project) contains the following elements: • A description of the existing botanical and wildlife resources in the study area (see Figure E5.1-1) • A discussion of agency consultation related to terrestrial resources • Summaries of the studies conducted by PacifiCorp on wildlife and vegetation • A summary of proposed enhancement measures • A discussion of continuing impacts E5.1 HISTORICAL TERRESTRIAL RESOURCES The terrestrial resources in the Project vicinity historically have been affected by humans for a long period of time. Much of the information on Native American use of the Klamath River Canyon comes from the archaeological investigations conducted by Gleason (2001). Native Americans have been part of the Klamath River ecosystem for at least the last 7,500 years (Gleason, 2001). The Upland Takelma, Shasta, Klamath, and Modoc tribes all used various portions of the study area; the Yurok Tribe historically used the lands along the Lower Klamath River. Before settlement by Europeans, Native Americans affected terrestrial resources through clearing vegetation for villages; harvesting plants and animals for food, medicine, and other uses; and using fire to manage vegetation. The most intensive uses occurred close to the river. Apparently, many of the flat terraces in the canyon were used at one time or another as village- sized settlements. The existing Topsy Grade Road is near the site of a Native American trail. Beginning in about 1870, homesteaders established ranches in the Klamath River Canyon. Apparently, the canyon was mostly unoccupied by any Native American tribes after this time.

    Preliminary Economic Assessment of Dam Removal: The Klamath River Sarah A. Kruse, Ph.D. Astrid J. Scholz, Ph.D. Ecotrust January 31, 2006 721 NW Ninth Ave, Suite 200 Portland, OR 97209 www.ecotrust.org Preliminary Economic Assessment of Dam Removal: The Klamath River 1. INTRODUCTION The Klamath River flows over 250 miles from its headwaters in southwestern Oregon through northern California to the coast, where it drains into the Pacific Ocean. The Klamath is one of only three rivers to pass through the Cascades and is the second largest river in California. It is divided into two distinct sections, the Upper and the Lower. A significant amount of water is diverted from the Upper Klamath River for agricultural irrigation within the federal Klamath Irrigation Project, while much of the Lower Klamath runs through the Klamath National Forest. The river and its fish, particularly salmon, are considered sacred by the Native Tribes that live nearby, including the Yurok, Hupa, Karuk and Klamath Tribes. Historically, the river was considered prime habitat for a variety of species including: Chinook salmon, coho salmon, silver salmon, steelhead trout and Pacific lamprey. Once the third-largest river for salmon spawning on the West Coast, the Klamath River now produces only a fraction of its historic levels. Six dams, constructed between 1908 and 1962, truncate the river and prevent salmon, as well as other anadromous species, from moving upstream. The lowest dam, Iron Gate, sits at river mile 190 and is the current limit of upstream passage for

  • Occurrences of the Lost River Sucker, Deltistes Luxatus (Cope), and Shortnose Sucker, Chasmistes Brevirostris Cope, in Northern California'
    • REPRINT FROM Calif. Fish and Game, 51 (2 ) : 68-73. 1965. OCCURRENCES OF THE LOST RIVER SUCKER, DELTISTES LUXATUS (COPE), AND SHORTNOSE SUCKER, CHASMISTES BREVIROSTRIS COPE, IN NORTHERN CALIFORNIA' MILLARD COOTS Inland Fisheries, Region 1 California Department of Fish and Game The Lost River sucker and the shortnose sucker are added to the fresh- water fish fauna of California. Their distribution, a brief discussion of habits, and meristic data are included. Recent captures of the Lost River sucker and the shortnose sucker represent additions to the freshwater fish fauna of California (Shapo- valov, Dill, and Cordone, 1959). The ranges of these suckers (family Catostomidae) previously were given as the Klamath Lakes drainage in Oregon (Schultz, 1936; Eddy, 1957). Gilbert (1898) stated that Del- tistes apparently were resident during most of the year in the deeper waters of Upper Klamath Lake and Tule Lakes (Figure 1). On May 15, 1955, Ned Dollahite, California Department of Fish and Game, collected a mature shortnose sucker from Boles Creek, Modoc County, near Steele Swamp Ranch. I saw additional specimens in the same vicinity on May 10, 1960, which were swimming upstream in an apparent spawning migration. Boles Creek is an intermittent tribu- tary of Willow Creek, the principal stream entering Clear Lake Reser- voir. Lost River originates from Clear Lake Reservoir, flows northward into Oregon, eventually re-enters California, and discharges into Tule Lake, its natural terminus. Lost River is now connected to the Klamath River by the Lost River Diversion Canal. Specimens of the shortnose and Lost River suckers were first collected from Copco Lake, Siskiyou County, on November 20, 1956.
