Document Description
KRRC proposes to drill and collect seven sediment core samples from Iron Gate and Copco reservoirs (three in Iron Gate and four in Copco) and to collect eighteen sediment grab samples (nine from Iron Gate and nine from Copco) to determine the vertical extent and characteristics of sediments in the two reservoirs. The project will temporary disturb 0.003 acres for the core samples and approx 0.24 cy for the grab samples. The KRRC will drill 6-in core samples in both reservoirs and use a Van Veen sediment grab sampler for the grab samples in each reservoir. The project's purpose is to collect geotechnical information about the reservoir substrate and sediments to progress design and planning for decommissioning of the Klamath dams and for restoration planning.
