USGS Trains Klamath Tribal Community on Sediment Sampling
USGS hydrologists provide training to environmental program staff from five tribes along the lower Klamath River on how to sample for suspended sediment.
During the week of June 25-29, USGS hydrologists from Oregon and California Water Science Centers will provide training to environmental program staff from five tribes along the lower Klamath River on how to sample for suspended sediment. Also contributing to the class will be sampling and cableway safety experts from Cascades Volcano Observatory and from the Montana Water Science Center. The training is in preparation for the start of a network of sites where suspended-sediment concentrations will be measured, in partnership between USGS and several of the participating tribes, to establish baseline sediment concentrations in the river. Additional future work is expected as the network may be expanded to additional sites as the 2021 removal of four dams on the Klamath River approaches. Among the topics will be cableway safety, operation of automatic samplers and turbidity probes, and USGS protocols for depth and width integrated sampling for suspended sediment. The training class will also offer an opportunity for USGS and tribal staff to work out logistics for the shared responsibilities for sampling, as well as maintenance of monitoring equipment, as the project is implemented. Funding for the training program is partially from the TESNAR program, and partially from the funds for the network that is being established for measuring sediment concentrations.
In 1992, the USGS began studying possible causes for the change in trophic status of Upper Klamath Lake. Since then research has expanded to include groundwater, geomorphology, streamflow forecasting, and fish ecology.
