Klamath Basin Settlement Agreements

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.

Klamath River Basin Issues: An Overview of Water Use Conflicts

Congressional Research Service (CRS) | June 13th, 2002

Severe drought in 2001 affected the Klamath River Basin, an area on the California-Oregon border, exacerbating competition for scarce water resources and generating confl

Severe drought in 2001 affected the Klamath River Basin, an area on the California-Oregon border, exacerbating competition for scarce water resources and generating conflict among several interests – farmers, municipal and industrial users, commercial and sport fishermen, other recreationists, federal wildlife refuges, environmental groups, and Indian Tribes. The conflicts over water distribution and allocation are physically and legally complex, reflecting the varied and sometimes competing uses of limited water supplies in the Upper Basin. On April 6, 2001, the Bureau of Reclamation (Bureau), which has supplied water to farms in the Upper Basin for nearly 100 years, announced that “no water [would] be available” for farms normally receiving water from the Upper Klamath Lake, so that scarce water could be used to protect species listed as endangered or threatened under the Endangered Species Act (ESA). Water was available to some farmers from other sources (e.g., wells and other Bureau sources); however, many farmers were not able to plant or harvest crops due to severe cutbacks in water supplies. Emotions ran high on all sides of the issues, and the water control gates were unlawfully opened by protesters. Although the Basin has received significantly more precipitation in 2002, many issues remain in dispute. In addition, several judicial decisions have affected the issues with respect to the listed species as well as tribal rights. On May 31, 2002, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service both issued Final Biological Opinions on the Bureau’s 10-year Operation Plan for the Klamath Project. The agencies found that the Bureau’s proposed action is likely to jeopardize the continued existence of the two listed suckers and coho salmon, as well as result in the adverse modification of proposed critical habitat; however, both Opinions also included “reasonable and prudent alternatives” for operating the Project that would remove the jeopardizing effects of the proposed action. However, on June 3, 2002, the Bureau formally rejected both Final Biological Opinions, but opted instead to operate under a one-year plan that it asserts complies with the Opinions. Independently, in March 2002, the President appointed a high-level working group to develop solutions. Congress has responded to the controversy in a number of ways, including holding several oversight hearings and appropriating funds for water conservation activities in the area. This report provides background on the geographic, historic, and legal underpinnings of the current conflicts. Because the report focuses on the current conflicts, it deals primarily with Klamath Project operations in the Upper Klamath Basin and effects associated with water releases from Upper Klamath Lake.

Landscape Patterns and Processes of the McCormack-Williamson Tract and Surrounding Area: A framework for restoring a resilient and functional landscape

San Francisco Estuary Institute (SFEI) | March 25th, 2013

This report uses a reconstruction of the historical (early 19th century) Sacramento-San Joaquin Delta landscape in concert with contemporary data to elucidate restoration opportunities and constraints at the McCormack-Williamson Tract and within the surrounding Delta setting. Historical ecology encourages a landscape-level perspective of restoration through improved understanding of how physical processes created and maintained habitat mosaics in the recent past. This perception of landscapes can be used to evaluate current conditions and develop future restoration scenarios. We used the recently completed study of the historical Delta landscape (Whipple et al. 2012) to explore opportunities for the McCormack-Williamson Tract (MWT), a 1,645 acre (6.6 km2) tract along the Mokelumne River (Figure 1 and Figure 2). This site exemplifies the need to balance contemporary constraints to restoration (including existing infrastructure and flood protection concerns) with the goals of landscape-scale restoration. To explore some of the strategies and opportunities available to advance the landscape-scale restoration in the MWT area, three general concepts emerged: increasing landscape complexity, connectivity, and resilience. To understand how to interpret and improve these attributes, we developed conceptual models that placed the site within the larger landscapes of the historical Delta, relating local habitat features to regional controlling physical gradients. This aided interpretation of the contemporary physical landscape and allowed identification of opportunities and constraints to both short-term and long-term landscape-scale restoration. The historical record reveals features such as floodplain lakes, forests on natural river levees, and tidal channels in the study area. These and other features could be strategically incorporated into a restoration vision, or an “operational landscape unit” for this part of the Delta (Verhoeven et al. 2008). This type of perspective can help focus restoration targets, including the relative proportion and placement of different habitat types and landscape elements within project design constraints, maximizing the site’s ecological potential. The landscape-scale approach also identifies opportunities to improve ecological connectivity and long-term adaptability to sea level rise and other environmental changes. Some of these opportunities may be critical to the ecological function and resilience of the area, but may not be able to be addressed in the immediate MWT project design. Thus, a central component of translating a historical landscape perspective to site-scale design is envisioning an adaptable restoration process that spans short-term restoration actions that are possible within the site’s bounds, while maintaining a longer-term vision of what is needed at the landscape scale.

Letter to Governor Brown and the Legislature on the Salton Sea

The Little Hoover Commission in a letter sent Friday to Governor Brown and the Legislature again renewed its call for urgent action at the Salton Sea to prevent a massive public health, environmental and economic disaster in Southern California. Policymakers must replicate the effective approach taken to meet the state’s rewewable energy goals, wrote the Commission in its letter. Then, the Govenor gave a senior official the authority to do what it took to get projects through red tape at all levels of government. The model was remarkably simple: Get everyone together and get it done. The letter results from continuing oversight to which the Commission pledged in its 2015 report, Averting Disaster: Action Now for the Salton Sea. The Commission held an April 2016 hearing to get an update on the state’s progress in strategically managing the Salton Sea. It heard from the assistant secretary for Salton Sea policy at the Natural Resources Agency, as well as stakeholders from local government and the environmental community. The Commission’s letter acknowledges that momentum is building and that the state has made important progress in managing the sea, particularly with $80 million in funding in the Governor’s proposed 2016-17 budget. However, the Commission’s letter maintains that the state is not moving fast enough or allocating sufficient resources to prevent a disaster. Timelines have been delayed, short-term goals scarcely cover a fraction of exposed lakebed and much more than $80 million is needed to manage the sea.

Letter to State Water Board re: Flow Criteria that use Percent of Unimpaired Flow

Delta Stewardship Council (Delta Council) | May 22nd, 2012

The proposed use of percent of unimpaired flow is a step toward improving the outlook for fish and other wildlife utilizing the San Joaquin River and its tributaries. Fal

The proposed use of percent of unimpaired flow is a step toward improving the outlook for fish and other wildlife utilizing the San Joaquin River and its tributaries. Fall-run Chinook salmon are likely to benefit from February-through-June flows that are more natural in timing and variability than current flows. Compared with the existing maze of flow standards for the San Joaquin River and its tributaries, unimpaired flow comes closer to approximating natural flow, and it does so more transparently. Caveats include: (1) flow is but one of many stressors affecting fish and wildlife; (2) the choice of flow criteria and metrics needs to serve the broader needs of ecosystems as well as individual species; (3) a chosen percentage of unimpaired flow may fall short of the minimum needed by fish and wildlife in some years; and (4) such critical years are likely to become more common as Sierra Nevada snowpacks diminish as a consequence of climate change. This qualified endorsement is based on our reading of the “Technical Report on the Scientific Basis for Alternative San Joaquin River Flow and Southern Delta Salinity Objectives” (State Water Resources Control Board, February 2012).

Linking river management to species conservation using dynamic landscape-scale models

River Research and Applications (Wiley) | March 23rd, 2012

Efforts to conserve stream and river biota could benefit from tools that allow managers to evaluate landscape-scale changes in species distributions in response to water

Efforts to conserve stream and river biota could benefit from tools that allow managers to evaluate landscape-scale changes in species distributions in response to water management decisions. We present a framework and methods for integrating hydrology, geographic context and metapopulation processes to simulate effects of changes in streamflow on fish occupancy dynamics across a landscape of interconnected stream segments. We illustrate this approach using a 482 km2 catchment in the southeastern US supporting 50 or more stream fish species. A spatially distributed, deterministic and physically based hydrologic model is used to simulate daily streamflow for sub-basins composing the catchment. We use geographic data to characterize stream segments with respect to channel size, confinement, position and connectedness within the stream network. Simulated streamflow dynamics are then applied to model fish metapopulation dynamics in stream segments, using hypothesized effects of streamflow magnitude and variability on population processes, conditioned by channel characteristics. The resulting time series simulate spatially explicit, annual changes in species occurrences or assemblage metrics (e.g. species richness) across the catchment as outcomes of management scenarios. Sensitivity analyses using alternative, plausible links between streamflow components and metapopulation processes, or allowing for alternative modes of fish dispersal, demonstrate large effects of ecological uncertainty on model outcomes and highlight needed research and monitoring. Nonetheless, with uncertainties explicitly acknowledged, dynamic, landscape-scale simulations may prove useful for quantitatively comparing river management alternatives with respect to species conservation.
