The Klamath River Basin, a region along the California-Oregon border, has been a focal point for local and national discussions on water resources and species management. Water management issues were brought to the forefront when severe drought conditions in 2001 exacerbated competition for scarce water resources and generated conflict among several interests—farmers; fishermen (commercial and sport); other recreationists; federal wildlife refuge managers; environmental organizations; and state, local, and tribal governments. Subsequent problems with Klamath Basin fisheries, in particular events in 2002 and 2006 (see " Previous Events ," below), and conflict over the relicensing of the Klamath Hydropower Project, exacerbated these conflicts. Low water conditions and a call for water by senior water rights holders in 2013 have again brought these issues to the forefront. Congress has oversight authority over federal activities in the Klamath Basin related to operation of the Bureau of Reclamation's (Reclamation's) Klamath Project; management of federal lands (including six national wildlife refuges, managed by the Fish and Wildlife Service); and implementation of Endangered Species Act (ESA; P.L. 93-205 ) and other federal laws. Previously, Congress has held hearings and appropriated funding to address issues in the Klamath Basin. Past congressional debate has generally focused on the ESA's role in water management, the operation of the Klamath Project, and other topics, such as supplemental support for parties impacted by federal policies. The Klamath Basin Restoration Agreement (KBRA) and the Klamath Hydroelectric Settlement (KHSA), collectively referred to as the Klamath a greements in this report, were signed in 2010 by a wide array of basin interests (although not all basin interests support the agreements). They aim to address many of the ongoing conflicts in the Klamath Basin. The KBRA would, among other things, set limits for water allocations for irrigators and wildlife refuges under a range of conditions related to the amount of water forecast in a given year; attempt to make available supplemental water and power supplies in the basin; and provide for restoration and monitoring of certain fish species. It also includes other assurances to settle ongoing water conflicts between basin tribes and other entities, although it would not settle all ongoing conflicts in the basin. The KHSA lays out a process that could lead to removal of four nonfederal hydroelectric dams currently owned and operated by a private entity, PacifiCorp. If carried out as envisioned, the project would be one of the largest, most complex dam removals in history. Under the KHSA, the Secretary of the Interior led a study process to determine whether removal of these dams is in the public interest. Most of this study process has been completed, but the final step—a determination by the Secretary—would require congressional authorization. Although the Klamath agreements require congressional authorization to move forward on key components, some activities under existing authorities have already been undertaken. Consideration of the agreements could result in Congress revisiting previous issues in the Klamath Basin, as well as considering new ones. This report focuses on congressional consideration of the Klamath agreements. It assumes some familiarity with the basin on the part of the reader. The Klamath River Basin is a largely sparsely populated area on the Oregon and California border with limited water resources (see Figure 1 ). Irrigated agriculture in the upper basin relies in large part on water provided by the Bureau of Reclamation's Klamath Project. Other farmers and ranchers (known as off-project irrigators) also rely on basin water supplies for irrigation. The area is home to six national wildlife refuges that rely on the same water supplies to sustain migratory bird populations and several Native American tribes that were historically dependent on lower and upper basin fish species. Two species of upper basin fish are currently listed as endangered under the ESA (the Lost River and shortnose sucker), and one species of lower basin fish is listed as threatened under the ESA (coho salmon, an anadromous fish). The basin also includes seven dams on the Klamath River and its tributaries, built between 1918 and 1962. Six of these dams are owned by PacifiCorp, a private company, and are known collectively as the Klamath Hydroelectric Project (KHP). Historically, all but one of the dams produced hydroelectric power for the basin, including low-cost power for Klamath Project irrigators. The original Federal Energy Regulatory Commission (FERC) license to operate the KHP expired in 2006, and PacifiCorp applied for relicensing of the project in 2004. To date, a new long-term license has not been granted because of the lack of state certification under Section 401 of the Clean Water Act (P.L. 92-500), as well as ongoing uncertainty related to fish passage upgrades and the status of the Klamath agreements, discussed below. In the absence of a new FERC license, the project continues to operate under a temporary annual license with the same conditions of the expired FERC license. While water and species management issues have been prevalent throughout the history of the Klamath Project, recent congressional consideration related to Klamath Basin usually centers on one or more of three seminal events that occurred in 2001, 2002, and 2006. These events resulted in press coverage, legal conflicts, and studies that framed the negotiations and agreements currently at issue. More recently, in the summer of 2013, a call on water rights under the newly released Oregon water rights adjudication resulted in limitations on water deliveries for junior water rights holders in the upper part of the basin. Several events have put the Klamath region in the national spotlight. In 2001, as a result of previous biological opinions by the federal Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS), the Bureau of Reclamation severely curtailed water deliveries to the Klamath Project to provide more water for endangered fish in the basin and to prevent their extinction. These allocations were met with protests by area irrigators, who threatened to open irrigation head gates by force. Later, in 2002, irrigators received more water than had been allocated in 2001, but thousands of fish (mainly Chinook salmon) died on the lower part of the Klamath River, largely due to poor water conditions and fish health in that part of the basin. In 2006, the National Oceanic and Atmospheric Administration severely restricted ocean fishing for salmon in the region due to low numbers of naturally spawning adults (due in part to residual effects of the aforementioned 2002 event). This restriction resulted in a large decrease in that year's commercial and recreational salmon catch compared to previous years. The federal government provided emergency funding in response to these and other events in the Klamath Basin. The funding included at least $170 million in addition to regular programmatic expenditures over the last decade. For instance, for the 2001 and 2006 events, the federal government provided approximately $35 million and $60 million in emergency aid, respectively. Aid in addition to regular agency programs and appropriations was also provided in other years. Between 2002 and 2007, Reclamation spent $14 million on a pilot water bank to alleviate water shortages. Due to drought events in 2010, an additional $10 million in supplemental appropriations was provided to the Klamath Basin in that year and $2 million was provided for a Klamath Drought Initiative by the U.S. Department of Agriculture (USDA). The 2002 farm bill provided $50 million to the Klamath Basin, and USDA funding was also provided under other general authorities and programs authorized in the 2002 and 2008 farm bills. In addition to these events, an Oregon state water rights adjudication in the basin that was first initiated in the 1970s received added attention in 2013 (See box above, "Klamath Water Rights Adjudication"). At the conclusion of the adjudication's administrative phase, the state of Oregon upheld a number of previous water rights claims including, among other things, that the Klamath Tribes have water rights with a date of "time immemorial." These water rights are now protected under Oregon law and were exercised over junior water rights holders in the basin for the first time in the summer of 2013. The 2013 "call" on water rights (in which senior water rights holders gave notice that their demands exceeded available flows) limited or shut off water deliveries to some junior water rights holders (for the most part, off-project irrigators) in the upper basin. In response to conflicts and other issues in the Klamath Basin, the federal government facilitated talks among multiple groups between 2002 and 2010, including formal negotiations to reach two major settlement agreements between 2006 and 2010. Participants in negotiations included state governments, tribes, counties, irrigators, fishermen, conservation groups, and hydropower facility owners and users. The goal of the negotiations was a long-term solution to the multiple water and endangered species issues in the Klamath Basin, including the aforementioned issues associated with irrigation deliveries and flows for fish, as well as potential issues associated with pending water rights adjudications and relicensing of the basin's hydroelectric dams. The two agreements that resulted from the negotiations, the KBRA and the KHSA, are officially linked in that signatories see them as complementary and do not support authorization of one agreement without the other. Originally, both agreements were set to expire without congressional authorization by 2012, but this deadline has been extended to 2014. In response to concerns and outstanding issues in the upper basin, in 2013 a task force was convened to incorporate additional issues not addressed by the KBRA and KHSA. Among other things, it resulted in an additional settlement agreement in late 2013, the " Upper Klamath Basin Settlement Agreement ," discussed below. The KBRA was negotiated by stakeholders and other groups in the Klamath Basin. It was agreed to by more than 40 signatories, or parties, although not all interests in the basin support it. Broadly speaking, under certain conditions, parties to the KBRA promise to support diversions for Klamath Project irrigators and federal wildlife refuges that correlate to a given year's forecast inflows into Upper Klamath Lake. Water that is surplus to these inflows and not subject to other valid water rights (e.g., off-project diversions) would be allocated to other uses, including instream flows (see Table 1 for an abbreviated summary of this arrangement). In exchange for this support, environmental interests would gain additional federal and state funding for fisheries restoration, some of the aforementioned surplus water supplies, and related assurances for dam removal under the KHSA (which is expected to restore fisheries). Parties have also agreed that the ESA will not be amended under the agreement. For their part, three of the four largest tribes in the basin agreed to support the project and refuge diversions and not make a call on certain water rights in exchange for the aforementioned restoration actions, federal actions to restore fisheries, and economic aid. The exact projections of the effects of the KBRA allocations on various water users are subject to debate. However, compared to recent water years, the allocations are generally expected to result in less water for Klamath Project irrigators in wet years but more certainty—and potentially greater allocations than may have been the case otherwise—in dry years. Under the agreement, area irrigators are also promised funding to develop low-cost power to replace hydropower previously provided by the PacifiCorp dams, as well as funding to potentially make available more water supplies through means yet to be determined. Irrigators who did not initially agree to the KBRA, including some off-project irrigators in the upper basin, were not subject to the KBRA's assurances as they relate to tribal water rights. However, these irrigators have subsequently come to an agreement with the Klamath tribes that may prevent future curtailment of deliveries in exchange for promised retirement of some water rights and support for the KBRA and KHSA. The federal government is not party to the KBRA until Congress enacts authorizing legislation. Some of the actions envisioned by the KBRA have been interpreted as not being authorized and would require significant federal appropriations to go forward. Initial estimates stated that total federal costs to implement the Klamath agreements would be $798.5 million or $536 million over 15 years (depending on the assumptions used). A 2013 revision to these figures clarified that the "new" appropriations needing to be authorized to implement the agreements would total approximately $250 million over 15 years. The KHSA initiates a process that could lead to removal of four nonfederal hydroelectric dams (J.C. Boyle, Iron Gate, Copco 1, and Copco 2) currently owned and operated by a private entity, PacifiCorp. The agreement also provides related assurances. Most significantly, the KHSA lays out a process for additional studies and environmental review by the Secretary of the Interior to consider removal of the dams (known as the Secretarial Determination ). Under the agreement, the facilities' removal would be paid for by ratepayers in California and Oregon ($200 million) and an assumed California Water Bond ($250 million). The entity responsible for removal (known as the Dam Removal Entity, or DRE) has yet to be defined. The KHSA also addresses the interim operation of the dams as well as proceedings that could lead to transfer, decommissioning and removal of the dams. The KHSA would transfer one dam (Keno Dam) to the Bureau of Reclamation, and it would initiate a process to decommission other resources associated with the project. In contrast to the KBRA, the federal government was party to the KHSA. Reclamation has interpreted some actions within the KHSA as not requiring an explicit authorization by Congress (i.e., as being authorized under existing, more general, authorities), and these actions have been completed. The central component of the KHSA, the dam removal study, was conducted under Reclamation's general authorities and finalized in October 2012. The Department of the Interior (DOI) and most parties agree that congressional authorization is necessary to make a final Secretarial Determination on dam removal and to move forward with that project. The Secretarial Determination was originally expected by March 2012. However, since no authorizing legislation has been enacted, the deadline (which was not binding) has passed. In July 2013, members of the Oregon congressional delegation requested that a separate task force, the Klamath Basin Task Force, be convened to discuss several outstanding issues not addressed in the Klamath agreements. These issues included (1) water rights conflicts in the upper basin that were not addressed in the KBRA and that led to decreased irrigation deliveries in summer 2013 (see above section, " Previous Events "); (2) power issues among both Klamath Project and off-project irrigators; and (3) the perceived need to reduce the overall cost of the Klamath agreements. The task force released its report on December 3, 2013. It recommended support for authorizing legislation with specific components in addition to the KBRA and KHSA, such as a new settlement agreement among water rights holders in the Upper Klamath Basin (which was not provided for in the original KBRA). It also recommended the inclusion of authority to serve off-project irrigators with the same low-cost power envisioned for Klamath Project irrigators under the KBRA. Finally, it addressed cost concerns by recommending that any authorizing legislation for the Klamath agreements include only new authorities and authorizations of appropriations needed to execute the agreements at a total cost of $250 million over 15 years. The new settlement agreement recommended by the task force, the Upper Klamath Basin Comprehensive Agreement (the Upper Basin Settlement) was circulated for public comments and finalized in April 2014. It ostensibly would prevent a scenario such as the 2013 call on water rights from occurring again in exchange for, among other things, an additional 30,000 acre-feet per year in inflows into Upper Klamath Lake (resulting from reduced off-project agricultural uses in the upper basin); it also would provide for certain riparian restoration actions and certain regulatory assurances related to the ESA. In exchange, senior water rights holders have agreed to not make a call on junior water rights similar to the one made in 2013. To be implemented, the Upper Klamath Basin agreement would need to be ratified along with the KBRA in any future authorizing legislation. The Klamath agreements require congressional authorization to be implemented. In the 114 th Congress, S. 133 would authorize the Klamath agreements, with certain changes. In the 113 th Congress, two bills were proposed to authorize the agreements: S. 2379 and S. 2727 . S. 133 would provide congressional authorization of the actions described under the KBRA, the KHSA, and the Upper Klamath Basin agreement. It would authorize approximately $250 million in new federal activities envisioned under the KBRA and the Upper Basin Settlement for various actions in the on-project plan. Some of the prominent activities from the agreements that would be authorized (either directly or by reference) in the bill include a drought response plan, potential water rights retirement for certain junior water rights holders, economic development payments and activities for tribes, ecosystem restoration activities, and provision of low-cost power for project and off-project irrigators. S. 133 would also provide congressional authorization for certain steps under the KHSA that are important to the dam removal process moving forward. In addition to authorization of new activities in the Klamath agreements, the bill also includes assurances that certain preexisting rights and authorities (e.g., specific tribal claims/rights) would not be affected. Other significant changes to Klamath authorizing legislation have been made over time and are included in S. 133 . Among other things, the current legislation alters the proposed structure of the dam removal arrangement so that the dam removal determination under the KHSA would be made jointly by DOI and the states of Oregon and California (rather than being made solely by DOI with concurrence by the states). Similar to legislation in the 113 th Congress, S. 133 would add new reporting requirements for dam removal (including a report on planned facilities removal to be published one to two years prior to the removal of the dams) and ecosystem restoration, plus several smaller alterations to individual provisions of the agreements. Among other things, it would direct that dam removal costs include "reasonable compensation" for property owners affected by dam removal and would alter the disposition of certain revenues from FWS lands in the basin. In considering legislation related to Klamath restoration, Congress may focus on a number of issues, including the cost of implementing the legislation, its position on specific strategies and actions in the two agreements versus the status quo, and the potential for future disruptions in water supply deliveries in the basin. A brief discussion of some of these issues is provided below. The role of the federal government in the Klamath Basin centers largely on operation of the Bureau of Reclamation's Klamath Project, management of several national wildlife refuges and other fish and wildlife resources under the ESA, and tribal trust responsibilities. The federal role has been contentious in the past and is a central question related to congressional consideration of the Klamath agreements. Both agreements assume numerous actions by the federal government, and, as noted earlier, a subset of these actions cannot go forward absent new congressional authorization. In particular, the agreements envision an expanded federal role in the Klamath Basin in regard to the dam removal process (i.e., a determination on dam removal), provision of payments for water rights retirement, and pursuit of low-cost power for irrigators, among other things. These actions are not currently authorized in the basin and have been proposed to alleviate ongoing conflicts. Without authorization of these provisions, some supporters of the KBRA and KHSA may withdraw their support for the agreements. Supporters of the Klamath agreements argue that because of the federal government's prominent role in the basin, including its role in the area's resource allocation conflicts, it has a responsibility to help solve these issues. These groups note that federal involvement, including operation of the Klamath Project, implementation of ESA, and management of fisheries and federal lands, is central to conflicts in the basin. They argue that the agreements represent a consensus achieved by a majority of basin interests that are traditionally opposed to one another and are the best opportunity to solve the region's problems going forward. They also argue that many of the expenses for these agreements are likely to be offset in the form of reduced future federal expenditures for litigation and emergency financial support. Supporters also note that the agreements will be a valuable source of jobs within the basin. Opponents of one or both of the agreements cite a number of reasons for their opposition. Some note that the federal government has no clear obligation to authorize and implement the agreements, and they contend that federal involvement in this case amounts to overreach that will harm the local economy. These opponents have argued that the activities represented in both agreements, such as dam removal and water quality improvements, could potentially occur through preexisting processes and authorities. Some also generally oppose the removal of operational dams and associated hydropower facilities, including those in the Klamath Basin, on principle because of the dams' status as an energy source. Finally, some argue against federal authorization of the Klamath agreements because they believe that specific components of the agreements will undermine existing federal laws (e.g., the ESA) or federal responsibilities (e.g., tribal trust responsibilities) or that they will fail to achieve their stated goals (e.g., fisheries restoration). Some Members of Congress have expressed concerns about the cost to the federal government to implement the agreements. Most have assumed that the majority of actions in the KBRA would be federally funded, including the costs for the on-project plan, fisheries restoration, and tribal components of the agreement. A detailed discussion of the estimated costs for the agreements (in particular those for the KBRA) and how they have changed over time is provided below. There have been multiple estimates of the cost to implement the Klamath agreements, and in some cases these have contradicted one another or employed differing assumptions. The original 2010 KBRA estimated $970 million (in 2007 dollars) for the total cost to implement the KBRA over a 10-year window. Most of these costs were assumed to be incurred by the federal government, although the exact split was not specified. In 2011, this figure was revised to estimate the federal government's portion of expenses over a newly extended 15-year window. This estimate indicated that the federal cost to implement the agreement over 15 years would be $795 million (2007 dollars). Thus, there was a reduction in the estimated costs using constant 2007 dollars. The 2011 revision reflected increased state commitments for some activities and altered assumptions in other areas. The 2011 estimate also included an estimate of "base" funding already being spent in the basin that could potentially reduce the "new" costs of the agreements to the federal government, but it did not estimate the amount of budget authority required for previously unauthorized activities. The first two estimates were most recently revised in a December 2013 report by the Klamath Basin Task Force, which estimated that $923 million (in 2014 dollars) in federal funds would be required to implement the agreements and that $250 million of this funding would come from newly authorized appropriations. The 2013 report also provided a retroactive estimate for the new authorizations of appropriations under the 2011 document. Table 2 , below, provides a comparison of these costs, including estimates in constant dollars. In contrast to the KBRA, cost estimates to implement the KHSA have not changed substantially since the original agreement. They also have not garnered as much attention from Congress because states are the primary entities responsible for funding dam removal under the KHSA. Previous studies by DOI to inform the Secretarial Determination estimated potential costs of approximately $290 million for dam removal, which is less than the combined amount anticipated to be available from ratepayers ($200 million) and the state of California ($250 million). One potential issue related to these costs is whether the dam removal determination will recommend the federal government as the dam removal entity. If so, a major question may be how additional costs for dam removal, such as cost overruns and costs resulting from potential lawsuits, would be handled. There is no formal estimate of potential future savings to state and federal governments associated with the agreements. Supporters point to previous costs to federal and state governments that would be unlikely to occur if the agreements are implemented, including at least $170 million in supplemental aid for irrigators and fisheries that has been provided since 2001. Advocates also point to decreased costs for litigation as a result of agreements. Although the agreements would not prevent future litigation, supporters argue that, if authorized, they would obligate parties to pursue other dispute resolution mechanisms that are expected to be less costly and would thus render future litigation costs less likely. Opponents note that none of these savings are guaranteed under the agreements and that supplemental appropriations and expenditures for litigation may still be necessary. In addition to savings, supporters also argue that the KBRA and KHSA could create economic benefits, both in terms of traditional and "non-use" benefits. Studies commissioned to advise DOI's secretarial determination on dam removal estimated that the total potential value of restoration, including non-use values, could total $16 billion-$84 billion, depending on the assumptions and methodology used. Some dispute these estimates and argue that they are unrealistically large or derived from questionable methodologies. Obtaining authorization and appropriations for these activities from Congress may be difficult. In the 113 th and 114 th Congresses, authorization of new programs and projects by both chambers has been limited. Beyond authorization of new funds, some observers also note that it is unlikely that federal agencies will obtain the new appropriations envisioned for the KBRA in a constrained budgetary environment. Hypothetically, a lack of discretionary appropriations or overall progress associated with future actions assumed in the KBRA or KHSA could affect the status of support for either agreement among the parties and thus cause additional conflicts among the agreement's supporters. Supporters have for the most part acknowledged these difficulties, but they argue that initial authorization of the agreements is an important first step and that the basin's issues are important enough to warrant congressional authorization and funding. Some believe that congressional authorization of the agreements (in particular the KHSA) would be an implicit endorsement of dam removal. Since authority for the Secretary of the Interior to make a final determination on dam removal is a key step in the KHSA, some argue that authorization of the agreements is the primary opportunity for Congress to weigh in for or against this decision. Although it did not formally recommend dam removal, the study findings intended to inform the Secretary's dam removal determination did not find major drawbacks associated with this course of action. Thus, some have concluded that if Congress authorizes the dam removal determination to go forward, a finding that dam removal would be in the public interest is likely. While many in Congress support dam removal as a means to restore rivers, others see it as an unnecessary and expensive step that decreases the availability of renewable energy. Additionally, while the KHSA anticipates that ratepayers and the state of California will be the primary entities funding dam removal, the extent to which the federal government will be involved in this process remains unclear. Stakeholders disagree on whether dam removal would happen without the KHSA and the related determination by the Secretary of the Interior. Opponents have noted that PacifiCorp-funded dam removal would be likely under FERC relicensing conditions; however, PacifiCorp and other supporters of the KHSA note that a different outcome (such as fish passage upgrades) could occur under the FERC process for a number of reasons (for more information, see below section, " Stakeholder Views "). The extent to which the Klamath agreements will alter implementation of the ESA and other federal laws is a matter of disagreement. Previous biological opinions established minimum flows on the Klamath River for coho salmon, as well as actions intended to aid the recovery of Lost River and shortnose suckers. According to supporters, the Klamath agreements will be considered to the maximum extent practicable under the ESA. At the same time, both agreements state that implementation of the agreements shall not affect implementation of the ESA by DOI or the NMFS. A perceived conflict between these two objectives, and a lack of clarity on how exactly they will be interpreted and implemented, has resulted in ongoing disagreements among some stakeholders. While the agreements do not waive application of the ESA, some groups that were not signatories argue that certain provisions—in particular the defined water allocations for irrigators—would undermine the ESA. These groups note that the allocations for irrigators would provide more water than irrigators received under ESA stipulations during recent low water years and would thus decrease flows from amounts provided under recent biological opinions and provide less water for fisheries. They note that while other processes under the ESA would technically go forward, the assurances in the agreements, if adopted in legislation, could result in additional pressure on regulatory agencies to adopt biological opinions that allow the flows set forth in the proposed Water Resources Program. Supporters note that the Klamath agreements would provide for more resources and actions to improve habitat for fish species, which they argue are just as important as the difference in flows that could occur under some scenarios. Improvements under the KBRA, including new fish habitat and improved water quality, are assumed to result in greater fish abundance, which would in turn allow managers to forgo the previous restrictive flows that were provided under the ESA. Furthermore, some believe that the KBRA could in the long term encourage more cooperative actions, which could improve the likelihood of listed species' recovery and are preferable to previous "top-down" regulatory actions. While stakeholder views on the Klamath agreements can broadly be divided into those supporting the agreements and those opposed to one or both of the agreements, such a simple characterization may not do justice to the various motives, preferences, and specific interests of many of these groups. Although a majority of interest groups involved in initial settlement negotiations endorsed both agreements, reasons for support among these groups are varied and in some cases are likely to be contingent on specific parts of the agreements (e.g., guarantees related to water supplies, whether or not dam removal is provided for, etc.) going forward. Among those opposed to the agreements, reasons for opposition also vary widely. They include reasons ranging from perceived economic damages resulting from the agreements to the agreements' overall lack of environmental protections or effect on implementation of existing laws. Among those supporting the Klamath agreements are all the parties listed as nonfederal parties within both the KBRA and the KHSA. For the KBRA, this includes 5 state agencies in Oregon and California, 3 tribes, 1 county (Humbolt County, in California), 25 parties related to the Reclamation Project, some off-project interests, and several other groups (including environmental interests). These same groups are also party to the KHSA. Other groups and individuals were not party to the agreements but have stated their support for them. These include, most recently, off-project irrigators in the upper basin who have agreed to support the Klamath agreements under the Upper Klamath Basin Agreement in Principle, signed in April 2014. Notably, supporters have agreed to support authorizing legislation for both agreements (e.g., KBRA signatories have backed enactment of the KHSA) and have generally argued that the agreements themselves must be linked. The states of California and Oregon, as well as the Obama Administration, support the agreements because they represent a potential solution to the protracted resource conflicts in the upper and lower basins. Government representatives also have pointed to the costs that resulted from previous conflicts in the basin, including supplemental aid, crop insurance, mitigation actions, and litigation costs. Other groups have chosen to support the agreements not only for their potential to end conflicts in the basin but also because they include specific provisions that are important to certain groups. For instance, environmental groups have pledged to support the allocations for irrigation absent a similar allocation for fish in exchange for assurances of dam removal under the KHSA and other promised fisheries restoration actions under the KBRA. Among irrigators, those on the Klamath Project have pledged to support restoration provisions and less water in wet years in exchange for benefits from water supplies in dry years that presumably would be higher than under the status quo. Approximately half of the off-project irrigators in the upper basin support the agreements, in some cases because the agreements offer potential alternatives that are preferable to losing water deliveries outright due to their junior water rights status. For its part, PacifiCorp notes that it supports removal of its four dams under the KHSA because retirement of the dams under the terms of the KHSA reportedly represents a more cost-effective option for its ratepayers than FERC relicensing. Previously there have been disagreements over which option the company would pursue in absence of the KHSA: FERC relicensing for ongoing operations on all four dams (which would entail costly improvements for fish passage, and altered operations for water quality) or a surrender of its license and related decommissioning of some or all of the Klamath hydropower projects. Both options would likely be costly for PacifiCorp and its ratepayers, and could potentially cost the company more than the arrangement under the KHSA. The KHSA also has the added benefit of allowing the company to operate the dams under the current management regime through 2019, through annual extensions to the project's FERC license. Some groups and individuals oppose the Klamath agreements and their authorization. Some of these parties were initially involved in settlement negotiations but dropped out for various reasons, while others were not invited to participate in negotiations because they were not seen as representing significant interests. Still others, including county officials in the areas of the Reclamation project and dams, oppose the agreements in their elected capacities. Notable opponents of the Klamath agreements include local officials in Klamath County in Oregon and Siskiyou County in California, the Hoopa Valley and Resighini Rancheria and Quartz Valley tribes, the Northcoast Environmental Center, Waterwatch of Oregon, Oregon Wild, and others. As noted above, some groups that initially opposed the agreements, including approximately half of the off-project irrigators in the upper basin, recently reached an agreement, the Upper Basin Agreement, the effectiveness of which is tied to the authorization of the KBRA and KHSA. Other opponents, including Klamath and Siskiyou County, have since stated their opposition to that agreement for its ties to the KBRA and KHSA (which they also oppose). Some groups oppose the agreements because they believe the agreements will further damage the region's economy. Some off-project users continue to oppose the agreements (including the Upper Basin Settlement) because of economic damages to farmers resulting from water rights retirement and restoration requirements. Siskiyou County has opposed the agreements for a number of reasons, including the assertion that the PacifiCorp dams provide flood protection and economic benefits for downstream areas. Some residents and officials in these areas also oppose dam removal because of an expected loss of property taxes associated with certain lands that will lose lake frontage when the dams are removed. Others argue that the agreements do too little to benefit fisheries and give up too much to farmers and other interests. For instance, the Hoopa Valley Tribe has been critical of the agreements because it feels that the provisions of the KBRA have the potential to terminate the duty of the United States to assert and protect tribal fishery rights when they conflict with operation of the Klamath Reclamation Project. The tribe argues that the KBRA would subordinate its senior priority water rights to the junior water rights of the irrigation project. Some opponents have also focused on the uncertain nature of fisheries restoration in the Klamath under the KBRA. Some contend that these uncertainties were highlighted in expert panels as a part of the larger DOI dam removal study process but were not adequately acknowledged by DOI in its final studies. Some of these groups favor dam removal but argue that removal could be achieved through the existing FERC relicensing processes and does not need to be tied to the KBRA. They note that by providing annual renewals of the FERC license for the Klamath Hydroelectric Project, the KHSA allows the company to avoid project upgrades (or removal) that would otherwise be paid for by the company and benefit fisheries in the short term. Combined with a lack of performance metrics for fisheries restoration provisions and promises to not make a call on project water rights holders under the KBRA, these opponents assert that the agreements disproportionately benefit PacifiCorp and irrigators at the expense of fisheries. Some environmental groups oppose other provisions of the Klamath agreements and dropped out of negotiations as a result. Waterwatch of Oregon and Oregon Wild find fault with a number of the provisions in the agreements, including the lack of water supplies for fish and the inclusion of lease-land farming on wildlife refuges. Along with the Hoopa Valley Tribe, these groups have called for voiding the KHSA and resuming water quality certification processes under the Clean Water Act to force dam upgrades or removal through a separate process, which they argue will be more expedient and less costly for state and federal taxpayers (i.e., a process to be funded by PacifiCorp and potentially its ratepayers). The Yurok Tribe, which initially supported the Klamath agreements, issued a notice of withdrawal from the agreements in September 2015. Among other things, the tribe cited inaction by Congress and disagreements with the provisions of the Upper Klamath Settlement Agreement, in which it was not invited to participate. 

Summary: The Klamath River Basin on the California-Oregon border is a focal point for local and national discussions on water allocation and species protection. Previously, water and species management issues have exacerbated competition and generated conflict among several interests—farmers; Indian tribes; commercial and sport fishermen; federal water project and wildlife refuge managers; environmental groups; hydropower facility operators; and state, local, and tribal governments. Drought conditions and a call for water by senior water rights holders in 2013 have again brought these issues to the forefront. In 2010, the Secretary of the Interior and the governors of Oregon and California, along with multiple interest groups, announced the results of a multiyear negotiation process to resolve long-standing issues in the basin: two interrelated agreements, supported by the federal government and signed by the two states and numerous other parties. These agreements, known as the Klamath Basin Restoration Agreement (KBRA) and the Klamath Hydroelectric Settlement Agreement (KHSA), together aim to provide for water deliveries to irrigators and wildlife refuges, fish habitat restoration, and numerous other related actions. Generally, the KBRA provides for actions intended to restore Klamath fisheries and for assurances for water deliveries to wildlife refuges and federal project irrigators under certain circumstances, among other things. The KHSA lays out a process that could lead to the removal of four privately owned dams on the Klamath River. This dam removal would be one of the largest and most complex projects of its kind ever undertaken. Some parts of the Klamath agreements are being carried out under existing authorities. Studies to inform a determination on dam removal under the KHSA by the Secretary of the Interior are complete, and some restoration actions have been initiated. However, congressional authorization is required for the most significant components of the agreements to be implemented. The KBRA and KHSA did not address all outstanding issues in the basin. A water rights adjudication by the state of Oregon (in progress since the 1970s) is ongoing. In 2013, the adjudication reaffirmed "time immemorial" tribal water rights in the upper part of the Klamath Basin, confirming that tribal water rights are senior to those of other water rights holders. This resulted in a "call" on water rights (i.e., notice by senior water rights holders that their demands exceed available flows), and led to reductions to water supplies for some junior users during the low water year of 2013. To resolve these issues and prevent such a scenario from occurring again, a separate settlement agreement (the Upper Klamath Basin Settlement Agreement) was negotiated by stakeholders and finalized in April 2014. To be implemented, the agreement would need to be authorized along with the KBRA and KHSA. The KBRA and KHSA were originally set to expire in 2012 if no authorizing legislation was enacted, but they have since been extended (most recently through 2015). Parties may also withdraw individually from the agreements, and several parties initiated this process of withdrawal. In the 114th Congress, S. 133 would authorize the Klamath agreements, including a suite of new federal actions that have received support from disparate parties and are required for the agreements to be implemented. Previous legislation in the 113th Congress (S. 2379) was ordered to be reported out of the Senate Committee on Energy and Natural Resources on November 13, 2014.
