The Elwha River restoration project is a study of how the deconstruction of the Elwha Dam is affecting the fine sediment concentrations in salmon spawning habitat. Data will be used to monitor changes in the quality of salmon spawning habitat during and following dam removal. This data will be important for understanding factors limiting salmon recovery in this system. My lab work includes filtering water samples, burning off the organic material, and measuring the difference in order to determine how much fine sediment is being added to the spawning gravels in the river. It’s an interesting process observing the differences between the samples taken before and after deconstruction of the dam. It has been a great learning experience for me and has given me the chance to practice lab techniques in a professional environment while earning college credits toward my degree.
