Klamath Dam Removal Project - County Memorandum - Floodplains
Siskiyou County has recently received numerous inquiries from the public concerning changes to floodplains along the Klamath River following dam removal. The current information available to the public is directly from the California State Water Resources Control Board (SWRCB) Final Environmental Impact Report (FEIR). It is important to note that the floodplain maps presented for the "new" floodplain in these documents are based on anticipated and estimated changes that are expected to occur following the removal of the dams. The models conducted to produce the maps were developed by the United States Bureau of Reclamation in 2012.
We acknowledge that these documents are extensive, in-depth, and may pose challenges when navigating through their contents. In an effort to alleviate confusion and provide some clarity, the County has prepared a concise memorandum detailing estimated floodplain mapping and providing information on what the public can expect regarding new floodplain mapping following dam removal. This memorandum also provides, as an attachment, the models and mapping derived directly from the FEIR. To access additional floodplain images, we direct you to the original EIS and EIR model documents, which can be found through the provided links below.
We hope that by offering this memorandum, we can address some of the concerns and uncertainties expressed by the public. Please refer to the links below for access to the documents and the accompanying images extracted from them.
