Klamath Bird Observatory pre-proposal
Sarah M. Rockwell, Jaime L. Stephens, and John D. Alexander
Water rights and dam operations along the Klamath River in northern California have been controversial for decades. In April 2016, the amended Klamath Hydroelectric Settlement Agreement (KHSA) was signed by PacifiCorp and a diverse group of stakeholders proposing to remove four PacifiCorpowned dams (Iron Gate, Copco 1 and 2, and J. C. Boyle) known as the Lower Klamath Project. The Klamath River Renewal Corporation (KRRC) is a third-party, non-profit organization created as part of the amended KHSA to oversee the dam removal process. The removal of the Klamath River dams, currently planned to be completed by the end of 2023, represents the most extensive dam removal and river restoration project in U. S. history. It presents an exciting opportunity to study the ecological effects of large-scale dam removal, which are not currently well-understood. This work is timely – studies should be implemented in 2022 and/or 2023 to collect baseline data so that we can better inform dam removal planning and understand changes that occur post-dam removal.
Klamath Bird Observatory proposes applying the best available science and integrating avian focal species into conservation planning as a component of the Klamath River dam removal and restoration process. Birds are considered excellent indicators of ecosystem health because they respond relatively quickly to habitat change, individual focal species are sensitive to environmental variation at multiple trophic levels and at multiple spatial scales, and as a community, birds are relatively easy and cost-effective to monitor (RHJV 2004). Our data-rich tools provide quantitative measures of watershed health that can be used to evaluate management alternatives, set measurable management targets, inform on-the-ground restoration design, and provide a cost-effective means to monitor restoration outcomes and evaluate effectiveness of management actions. We will apply results from decades of monitoring in the Klamath Watershed, including management-relevant studies of Gold Ray Dam removal (Stephens 2017) and the Trinity River Restoration Program (Stephens et al. 2016, Rockwell and Stephens 2018, Stephens and Rockwell 2019), along with established bird and habitat conservation plans(e.g., RHJV 2004) and site-level monitoring, to inform adaptive management of restoration.
We propose the following applications of birds as indicator species to inform management, set restoration targets, and measure success:
Despite the number of dam removals planned in the U.S., dam removal science is in its infancy (Bellmore et al. 2016). Here in the Klamath-Siskiyou Bioregion, we are well-positioned with established science to inform dam removal planning, develop a monitoring strategy to inform adaptive restoration and measure the success of ecological function of both in-stream and riparian ecosystems. The Klamath dam removals, one of the largest river restoration projects in history, provide a unique and timely opportunity to study ecological response to large-scale dam removal, an aspect that is commonly overlooked. Knowledge of these effects will help inform future dam removal processes and restoration efforts.
